Make a staircase from a profile with your own hands. How to make the frame of a metal staircase from a profile pipe with your own hands: drawings, calculations. Types of stairs made of profile pipes

There are various ways design and production of stairs. The choice depends on the style of the interior and the personal preferences of the residents. Quite popular among the many options is a staircase made of profile pipe. To get this reliable design, you can contact special companies or call a private master. But, if you have the necessary skills, it is possible to make a staircase from a profile using your own efforts, using our instructions.

Advantages of a staircase made from a profile pipe

The design has a number of positive features:

The ability to create any type of staircase: both a regular marching staircase and a spiral or extension staircase. The values of the parameters of bends and angles will not particularly affect the complexity.
Structures that use metal can be combined using wood, glass, plastic or even concrete to decorate the steps. This will allow you to select appearance, matching the interior.
Profile pipes can be easily painted by applying any color using the powder method. Today, gold, silver and black with light metallic paints are especially popular.
High reliability and strength are the undeniable qualities of stairs made from profile pipes.
good operational properties, durability. The material is resistant to mechanical and atmospheric influences.
In order to make a staircase from a profile pipe with your own hands, it will not take much time if you have good welding skills.
All complex elements frame can be made without outside help, correct cutting of workpieces is important. The rest of the work is welding the elements.
Installation of the staircase is easy to carry out at any stage of repair or during construction.
The cost of the profile is not high. An ordinary family can afford such a frame.

Features of work

When making a staircase from a profile pipe, it is necessary to take into account a number of features:

The staircase structure already bears heavy loads, and besides, metal is a fairly heavy material, so it is recommended to avoid additional weighting, for example, in the form of concrete steps.

Profile pipe can be used as a material for stair steps birch plywood, and for the railings - plastic gratings.

Anti-corrosion treatment and painting are a prerequisite for metal stairs, and its placement is completely unimportant - indoors or outdoors.
To connect elements supporting structure You can use bolts, but this is not the most reliable option. Classic welding of parts will be safer during operation. But at the same time, it is important to have a welding machine available and do everything with extreme caution. If you do not have welding skills, then it is better to entrust such work to professionals.
In the case of installing a ladder made of profiled pipe as a fire or emergency ladder, it is necessary to take into account the possibility of the formation of vibration processes. In order to avoid this, despite the strength of the material, it is recommended to reduce the span struts as much as possible or to further strengthen them.

Preparatory work

To determine the need for material, you need to make a small drawing future design, on which the dimensions are indicated. They will allow you to make calculations - the number of steps, the height of the structure, etc.

And of course, any work with metal is not complete without:

welding machine and packs of electrodes for it;
grinders and metal circles;
a hammer drill and a set of drills so that it is possible to install fastening crutches;
hammer and markers with meters.

For stairs that have a complex structural form- for example, helical or with a turntable - it would not be superfluous to number all the elements so as not to get confused during the work process.

Materials for the steps are also prepared at this stage.

Making a flight of stairs

Once again, it is worth recalling the loads on the staircase structure. They oblige all work to be carried out correctly and efficiently to ensure safe operation.

A staircase made of profiled pipe may have one or two stringers. This will depend on how wide you want the future product to be. Undoubtedly, more stringers will affect the strength of the stairs, which will lead to additional expenses on material and labor costs. If you are still planning one load-bearing support, then you can weld additional consoles on the side. This measure will help avoid sagging of the treads when exposed to heavy loads.

Let's consider the simplest design of a staircase made of profiled pipe.

Stages of work

The process begins by scalding the contour, the result of which should be the resulting rectangle. We will install a stage on it later.

Steps for external stairs can be made from reinforcement bars. It will cost less than wood and will last longer.

As a base we will use a profiled pipe with a cross-section of 10x10 centimeters. The advantage over a channel is that its use will reduce possible vibration without additional strengthening measures.
Guides are made by cutting the profile pipe so that the part at the cut point fits tightly onto the support at one end. Opposite end must be adjacent to the top support. This can be done by welding to both edges of the platform. They will help fixation. If we are talking about a simple flight of stairs, then the floor and ceiling will become such supports.
In order to be able to install the steps, it is necessary to weld the support frame. Do this between two supports.
To attach future steps, it is necessary to provide holes on the support frame. The treads are attached to anchor bolts.
The installation of railings and other attributes is carried out at the final stage, but the places for their fastenings must be prepared in advance.
The product is painted at the stage when the entire structure from the profiled pipe is assembled.
If you want to leave a gap between the wall and staircase structure(usually this is done for more comfortable gluing of wallpaper or the use of other materials to decorate the wall), then additional reinforcement of the structure must be provided. To do this, three crutches are hammered into the wall. The remaining segments of reinforcement can be used as these elements. These crutches must be driven under the main load-bearing inner tube and cook.
In the manufacture of external racks they are often used metal pipes. A platform is welded onto its bottom, and upper part cut according to the slope load-bearing beam, then it’s all cooked.

The use of a support pipe will help reduce possible vibration. And it itself can be used in the interior as a support for decorative elements. for example, for flower pots.

Fences can be mounted on the side of the frame. The material depends only on your taste. This arrangement of fencing will lead to an increase in the working width of the staircase span.

Making a spiral staircase

Its production is somewhat different from the marching one.

Stages of work

We will use a profile pipe as a support. round section. Its length is selected in accordance with the height of the premises in which the staircase is installed.
To fasten the treads, use a profile pipe of a larger cross-section, cutting it into 23-26 centimeters.

For correct installation steps must be cut perpendicular.

For fastening, you can use special sealing rings, which are welded into the sleeves and ground.
You can make a jig as a template (so that the steps are the same). To do this, use a pipe mandrel and wooden slats(can be replaced with pieces of chipboard). They must be glued together in such a way as to give the element the shape of a step.

The frame is assembled by placing sleeves on the central post. The resulting structure is installed on the prepared site, and the lower part of the rack is concreted to ensure greater strength and reliability.

Next, the steps are set at the required angle and welded together using small racks.
The steps are laid after the priming is completed and the painted surface has dried.

Making a “Goose Step” staircase

Staircase "Goose step" made of profile pipe

You can make a “goose step” staircase using a profile pipe square section . There are no special instructions for this type of construction. The frame will be a load-bearing stringer, made at a large angle (usually more than 40 degrees).

The difficulty here is only in making the steps, but you can use the creation of a template that will simplify the task a little, eliminating the need to constantly monitor the correctness of the angles.

The seams of the frame must be thoroughly sanded after finishing the welding work. Then apply the primer using anti-corrosion compounds. After this, they begin painting.

We must not forget that the steps must be mounted on a ready-made painted structure in order to avoid damage to the material of the steps, except in cases where the treads are made of metal.

Stairs made on the basis metal frame, are considered the strongest and most durable. In addition, the use of metal as the basis of the structure makes it possible to create unique compositions with incredible turns, large spans and other non-standard design solutions. Therefore, such a staircase can fit into any interior. We will tell you about the advantages metal structures, varieties of stairs made of profile pipes and provide instructions for the manufacture and installation of the structure.

Advantages and Disadvantages

A stair frame made from a profile pipe has many advantages over structures made from other materials:

high strength;
long service life;
speed of manufacturing a staircase base from a profile pipe;
the ability to implement any form of construction by using different elements fastenings;
low cost of building materials.

However, metal structures have several disadvantages:

Due to the significant mass of the frame, lighter and less durable materials such as wood, plastic and glass have to be used as the remaining elements of the staircase.
For the production of strong and beautiful design all basic connections must be made using a welding machine, that is, experience with this equipment is required.

Species

In addition to the usual attached metal products, there are marching, bolt and spiral staircases. Let's look at each type in more detail:

An extension ladder is the most simple design, which includes two parallel supports with steps installed perpendicularly between them.
Marching staircases differ more complex design, which involves installing steps on beams installed at a certain angle. This type of profile pipe product is mainly made by owners of private houses. Support elements designs can be bowstrings or stringers.
Spiral staircases. In this case, the steps have the shape of a triangle or a sector of a circle. On one side they are attached to the central support beam, and on the other – connected by railings. Such a structure is rarely made with one’s own hands. This is due not only to the inconvenience of using a steep design, but also to the complexity of its manufacture.
Bolt stairs. Here the steps are attached using powerful bolts (bolts) directly to the wall. WITH opposite side the ends are connected by balusters and railings. To install such a structure, a strong wall is required. If this is not the case, then you should pay attention to other options for staircase structures.

Thus, the most suitable for self-made are attached and marching design from a profile pipe. Let's find out how to make these devices with your own hands.

Gallery: Types of stairs made of profile pipes

The structure can only be installed if there is a strong wall. The spiral staircase is difficult to manufacture, but takes up little space Marching staircase can be installed both inside and outside the house An extension ladder made from a profile pipe is highly durable and easy to manufacture

Design calculation

The number of steps is determined as the ratio of the height of the future staircase to the height of the riser.
The length of the stringer is calculated in accordance with the Pythagorean theorem (the square of the diagonal is equal to the sum of the squares of the legs, that is, the vertical and horizontal projections of the future structure).
The load on the support beams can be calculated using the formula: G=1.1*mс+1.4*ml, where G is the maximum load on the stringer, mс is the mass of the steps; ml is the mass of all people who can be on the stairs at the same time.
The cross-section of a metal profile is determined by the formula: S=5.2*a*G*L/E, where S is the cross-section of the profile; a – step width; L – stringer length; E – elastic modulus of the material (for steel E=2,000,000 kgf/cm2).
The width of the stairs should be from 80 to 120 cm.
The optimal angle of inclination of the structure is 45°.
The maximum height of the steps is 20 cm, the minimum is 12 cm. The optimal tread depth is 30 cm.
The height of the handrails for adults should be 95 cm, and for children - 60 cm.

Required materials and tools

For self-production ladder from a profile pipe you will need:

Two square steel pipes with sides of 40 mm. Do not use profiles longer than 2.5 m as racks, as this will reduce the strength of the structure.
Sections of profile pipe about 30 cm long. If the staircase is small, then the length of the rungs can be reduced. The number of elements is selected depending on the length of the future structure with the calculation that the distance between steps should be 20 – 25 cm.
Metal corners (two for each crossbar).
Square plates with an area of 160 sq. mm.
Measuring tape and marker.
Corner grinder with a metal disc.
Sandpaper.
Primer for metal surfaces.
Varnish or paint for metal.
Profile for creating stringers;
Profile for constructing a frame for steps;
Blanks for steps (you can make it yourself from wooden planks or purchase a finished product);
Self-tapping screws for metal;
Grinder with a disc for cutting metal;
Screwdriver;
Welding machine;
Sandpaper;
Construction level and metal corner;
Concrete solution;
Powerful anchor bolts;
Primer and paint for metal surfaces.

Work order

The length of the crossbars must correspond to the estimated width of the stairs

The procedure is as follows:

Place on a flat floor metal supports. We place them strictly parallel to each other at a distance of 0.3 meters.
We make marks on the racks in accordance with the selected step location. In this case, the extreme marks should be at a distance of 15 – 20 cm from the ends of the supports.
In the marked places, perpendicular to the legs of the stairs, we weld corners that will serve as supports for the rungs.
We take two pre-prepared sections of pipe 30 cm long and weld them to the corners, one being grabbed from above and the other from the bottom of the future staircase. The result is a rectangular frame.
Similarly, we fasten the remaining crossbars along the entire length of the structure.
To prevent moisture from getting inside the product, we weld plates to the ends of the stairs.
All metal connections carefully clean with a grinder and sandpaper so that there are no sharp corners.
Apply a layer of primer to the product, followed by varnish or paint.

Helpful Hint: When the paint is dry, put rubber caps on the legs. This will increase the grip of the ladder on the surface.

Installation

After installing the support beams, the comb-shaped frame is installed

The sequence of constructing a single-flight staircase on a metal frame is as follows:

In accordance with the calculated data, we cut pipes for the support beams.
We install the support beams in a pre-selected location. We fasten them below and above anchor bolts. It is advisable to concrete the base load-bearing structure. The beams must be positioned strictly parallel to each other.
We take the profiles for the frame for the steps and cut them into segments to create a ridge.
We weld the pipe sections to the support beams, forming a comb-shaped frame for the steps. When installing each component, it is necessary to control the angle of inclination using building level. Maintain parallelism of structural elements.
After completing the welding work, we clean all seams and sharp corners sandpaper.
We cover the staircase frame with primer and paint.
After the paint has completely dried, we attach the blanks for the steps to the stringers. To do this, we use metal screws and a screwdriver.

On last stage wooden or plastic steps are attached to the stringers

This concludes the process of installing a single-flight staircase on a profile pipe frame.

If you have basic construction skills, then assembling and installing a high-quality staircase from a profile pipe will not be an impossible task for you. And by adhering to the above rules and recommendations, you can build a strong and durable structure.

Made from a profile steel pipe, this is a fairly popular design, as it has many advantages. As a rule, its construction is carried out experienced craftsmen, since it should be absolutely safe from all points of view. That is, to be able to calmly withstand any possible loads from moving people and cargo, and convenient for lifting and lowering everyone living in the house, including children and family members who have reached a respectable age.

Is it possible to install a staircase from a profile pipe with your own hands? The question is ambiguous, since its construction still requires very high specific skills. Of course, it would be more correct to entrust the installation to specialists. But if the owner of the house has basic engineering knowledge, has successful experience work with all the tools necessary in this case and have become accustomed to always counting on own strength, then additional information about this type of stairs and about installation work will not be superfluous for him.

Advantages of staircase designs made from profile pipes

A staircase made independently from profile pipes has a number of significant advantages over both wooden and finished metal structures that can be found on sale. These advantages include the following:

Opportunity to significantly save funds allocated from family budget for construction or repairs.
Properly manufactured and assembled structure the stairs will last a very long time, without the need for repairs and restoration.
This material makes it possible with equal success to produce almost any type of staircase, even one with the most intricate design.
Profile steel pipe goes well with other materials, both technical and operational characteristics, and in its ability to “fit” into any interior style.
The advantages include the speed of manufacturing parts and their installation. But this advantage of metal structures will only be true if the master has perfect command of the tools, and his work will be carried out according to pre-developed drawings with exact dimensions.
The construction of a staircase from a profile pipe can be done at any stage construction process, including in an already built house.
The metal structure, with appropriate processing and finishing, is suitable for installation both outside and inside the building. Its strength qualities, neat and aesthetic appearance give it versatility.

The high strength of rolled steel profiles makes it possible to produce a simplified version of the frame, in which the support for the steps is one profile pipe installed along the center line of the structure.

Types of stairs made of profile pipes

As mentioned above, almost any staircase design can be made from a profile pipe. To verify the correctness of this statement, it makes sense to consider some of them in more detail.

Marching staircase

A flight of stairs can consist of one or several flights, which, in turn, are connected to each other either by a horizontally installed transition platform, or by a section with winder steps. Both options are approximately equally popular, and the design is chosen depending on the area of the room in which it is planned to install the staircase.

A staircase consisting of one flight is most often installed in a spacious room. If you have to use it in a room of a smaller area, then in this case you have to give it a large angle of steepness. This is sometimes what you have to do when installing staircases to the attic or basement.

Single flight design installed inside two-story house, allows you to rationally use all the space under the stairs. For example, under it you can place a closet or a small storage room, and sometimes even a small bathroom.

Another area where single-flight stairs are used is the entrance to the house from the street, if the building is built on a high base. As a rule, in this case the march has a small height and a slight slope.

A two-flight staircase is often installed in a room designed specifically for this design - the so-called staircase. However, this option is quite possible in residential premises - it all depends on the area that can be allocated for the installation of an interfloor passage.

For maximum savings space, such stairs are often installed along walls converging in the corner, that is, marches are made perpendicular to each other. This option also allows you to create a small storage area under the stairs.

In the design of a staircase with two or more flights that are long, platforms are most often installed at the turns, which, among other things, give the frame higher strength than winder steps.

Many home owners prefer to design transition platforms for stairs with short spans. It should be noted that this option is really more convenient than winder steps, which have different widths along its length. Thus, the side of the step attached to the wall is much wider than the opposite side, located at the center of the turn. In this regard, there is a very significant risk of tripping and getting injured.

Prices for wooden stairs

wooden staircase

We can agree that a staircase with winder steps often looks more original, and also somewhat more compact. But, as mentioned above, this design option is less safe to use compared to stairs with similar basic parameters, but whose spans are connected by platforms. This is especially important to take into account in cases where elderly people or small children live in the house.

Of course, it also happens that the area allocated for the construction of the staircase does not allow for the construction of a platform between the flights. It is in this case that a section with winder steps is installed instead.

If for a number of reasons it is necessary to build a staircase with winder steps, then you will have to carefully calculate its parameters, since the design must fully meet existing rules safety of movement along it. Details on how to create a project and produce necessary calculations for subsequent installation, is suggested in the article on our portal.

Spiral staircase

A spiral staircase can be called the most compact design, since it takes up a minimum usable area premises. Such an interfloor passage can be “fitted into a space” with dimensions of only 1500×1500 mm.

Looks like spiral staircase, of course, is original and aesthetically pleasing, but such a compact design has quite a few disadvantages.

The first of them can be called lifting a massive piece of furniture along it to the second floor or household appliances It will be almost impossible, since this structure is not very convenient to climb even empty-handed. installed in case of emergency, that is, if it is impossible to erect another structure due to small area Houses. True, this is also practiced - a similar structure is created as an additional one, having more decorative functions, and for lifting large loads, the house also has a staircase.

If the area of the room allows and there is a desire to install aesthetic option staircases are similar to a spiral one, it is better to choose a rotary design similar to it. Having erected it, you will not have to install an additional straight staircase, since with such a design, with a significantly large turning radius and a large flight width, it is quite possible to lift any furniture to the second floor.

Prices for metal stairs

In a turning staircase, all steps are the same size, so there will be no inconvenience both during descent andrise to the second floor. However, this design is quite complex both in calculations and in installation. Therefore, its construction or at least the development of the project is best entrusted to experienced specialists.

Step ladder

A profile pipe can also be perfect for making a stepladder, which is often necessary in everyday life private house. In order to mount such a mobile staircase, you will need a profile pipe with a cross-section of 40×40 or 50×50 mm for the support posts, and 20×20 mm for the rungs-steps.

In addition to the profile pipe, a special hinge mechanism will be required. It is clear that the specific type is selected based on the cross-sectional dimensions of the profile pipe, since the hinge is put on the racks and then attached to them with self-tapping screws or bolts.

The hinges on the mounting areas have special holes through which they will be fixed to metal racks. In addition, the hinge design includes a stopper, which is designed to fix the ladder racks in the required position.

If you plan to make such a structure yourself, you need to bottom side fasten the ends of the racks or horizontal jumpers-stops, which will make the operation of the ladder safe.

Naturally, for the manufacture of any metal structure you will need special tools and the ability to work with them. A pre-drawn drawing of a stepladder is also necessary, which will make it much easier to produce installation work. As an example or “starting point”, one of the options is shown in the illustration above.

Types of frames made of profile pipes

One cannot ignore the question of what kind of frames can be used for staircases made from profile pipes. The material seems to be the same everywhere, but the principles of the structure have significant differences.

Prices for steps for stairs

The most economical option The use of a profile pipe in the manufacture of stairs is a frame on a central stringer. This option can be made in two versions - it is a broken stringer, repeating the shape of the steps, or a straight one, made from a profile pipe that is solid along the entire length of the flight.

A broken stringer is more difficult to manufacture, as it is assembled from separate sections of pipe, cut to fit right angle, which are connected to each other into a common part by welding. Then, on each of the horizontal surfaces the stringer is welded the so-called "sole"(installation pad) made of sheet metal 3÷4 mm thick. The tread boards will be attached to this “sole”. To fix them, four to six holes are pre-drilled in the metal plates. Self-tapping screws will be screwed into the wood through them. For this design, a profile pipe with a cross-sectional size of 80×60 mm may well be suitable.

The second version of the central stringer is made from one pipe, usually with a cross-sectional size of 100×50 mm, which is cut only at the ends, at a certain angle. Then, plates or peculiar legs are welded to the end parts of the pipe forming the span, with the help of which the stringer will be secured to the ceiling and to the floor.

Markings are made on the stringer pipe along which stands will be welded for installing the steps. The stands consist of a leg, also of a piece of profile pipe, with cut under the right angle (depending on the steepness of the flight of stairs) at the ends, onto which “soles” are welded with holes for fixing tread boards on them.

For massive stairs, a more reliable version of metal structures is usually chosen, consisting of straight stringers onto which frames for the steps are welded. For their base, a pipe of 80×60 or 100×50 mm is used, and for the manufacture of a frame for steps - profile 25x25 mm or even a corner with shelves of the same size, which gives certain savings in metal costs. In the lower and upper parts of the frame, stands cut from a metal sheet are fixed by welding.

More difficult option stairs made of profile pipes are broken design, consisting of two stringers, in some cases fastened together by jumpers.

How are they made and assembled? frame structures This type will be discussed in detail in the instruction table below.

Calculations main parameters of stairs made of profile pipes

Starting to talk about calculations, it is necessary to immediately talk about how to correctly decide on the choice of a profile pipe according to its size. The first thing to remember is that for a standard small home staircase with two stringers, you should not choose a pipe with too thick or thin walls. Metal that is too thick will make the structure too heavy, and a thin profile unreliable.

To correctly determine this parameter, you can refer to the data presented in this table. In this case, the length of the march is calculated between the support points. That is, it is possible to provide reinforcement elements - racks that rest against the floor surface and stringers to make the free span shorter, if necessary.

Table of maximum loads on flights of stairs, depending on their length and parameters of the profile pipe:

Length of the flight of stairs in mm	1000	2000	3000	4000	5000	6000
Pipe cross-section size and metal thickness mm
50×25×2	684	167	69	34	16	6
60×40×2	1255	308	130	66	35	17
80×40×2	1911	471	202	105	58	31
80×40×3	2672	658	281	146	81	43
80×60×3	3583	884	380	199	112	62
100×50×4	5489	1357	585	309	176	101

However, the pipe dimensions should be selected after the staircase design has been selected and its basic parameters have been determined, calculations have been made and a drawing has been drawn up.

So, to make a ladder you need to decide on the following parameters:

The number of marches in the structure.
The height of the stairs or each flight, and the slope angle, which should be the same along the entire length of the stairs, regardless of the number of flights.
The design of connecting two flights is a platform or winder steps.
Number, width and height of steps.
The perimeter of the staircase opening in the ceiling.
Based on the calculated dimensions and the drawn up drawing, the amount of material required for installation of the structure.

In each specific case, all these parameters may be different, since the area of the premises allocated for the stairs and the height of the ceilings also differ, so measurements are always made individually.

The dimensions of the ceiling opening will depend on the slope of the upper flight of the structure. And such an opening should begin in the place where the distance from the ceiling to the step of the stairs will be 2000 mm, that is, a little more growth tall man.

The slope angle of a flight of stairs depends on the height of the rise (which is the height of the flow plus the thickness of the floor) and the area that can be allocated for construction, that is, on the length of the horizontal projection of the flight onto the floor plane. If the size of the room does not allow one flight to be accommodated (and this happens quite often), it is divided into two or even more. In this case, the calculation will already be carried out for each march separately, but in compliance mandatory conditions– the angle of steepness and dimensions of the steps are maintained throughout the entire staircase.

Well, knowing these values, it is easy to determine the length of the span itself.

Below are two calculators that should help determine these values.

A staircase from a profile pipe is created with your own hands using a welded and prefabricated method. For its manufacture, attached, stationary and other options are considered. For clear example, options for installing the structure in the form of a direct, screw and mobile structure are discussed below.

Important Details

To reduce the weight of the profile structure, inserts made of wood, glass, stone and ceramics are used.
A do-it-yourself extension ladder from a profile pipe is made as an addition to the porch, external access to the attic and installation indoors.
To create steps, profiled pipes with a cross-section of 5-7.4 cm are used. Shaking and vibration can be eliminated by reducing the length of the racks in the spans.
The inclination of the steps is 1:2 or 1:2.5, which corresponds to an ascent angle of 30 to 40 degrees.
A correctly designed do-it-yourself staircase made from a profile pipe in the drawings has no more than 18 steps. Subject to availability high ceilings, a platform is being built between the marches.
For convenience, an odd number of steps is created in the march. This allows you to start and end your step on the same foot.
The height of the steps is 15 – 21 cm.
The width of the steps is 30 cm. The smaller the angle of inclination, the wider the treads.

A do-it-yourself metal staircase made from a profile pipe can have an alternative in the form of two channels. Initially, the support frame is welded, then the frame for the steps. It is placed in two ways:

On top of the channel;
Inside the frame.

In the first option, the corners are welded to top shelf channel And in the second case, preliminary fastening of the corners to the inclined beams inside is created. The remaining parts of the step frame are welded to them. Below is a do-it-yourself staircase made from a profile pipe in the photo.

Preparation of materials

Channel 16 (height 16 cm, shelf width 6.4 cm) with a length commensurate with the flight. You will need 2 beams.
Thick-walled profile 4x4 cm. Its quantity is determined by the number of steps. To create a small march you will need 20 linear meters.

Tools for constructing a march:

Saw for metal structures (pendulum version).
Drilling machine.
Welding.
Electric drill.

Installation steps:

An interfloor staircase made from a profile pipe with your own hands begins with cutting the stringers to the required parameters so that after installation they form an abutment on the floor with the flat side of the cut.
For a more durable fixation on the floors of the first and second floors, metal beams are laid to the concrete base under the floor surface (a channel with parameters of 22 cm can be used). The length of the beams should be greater than the width of the stairs.
The load-bearing channels are attached to the embedded beams. Welding is used for this.

Here you can find out in detail how to make a staircase from a profile pipe with your own hands in the video:

Blanks for rectangular steps are created from the profile.

The workpieces are mounted on guides and welded to them. To create reinforcement for the structure, vertical supporting parts from the same pipe are used.
To make the device lighter, steel corners can be used instead of pipes.
The frame is cleaned and painted to prevent damage to the structure.
Solid treads are laid on a metal base with further fastening using self-tapping screws. To do this, the gaps are pre-drilled.
Supports in the form of pillars are welded on the sides of the guide channels, and handrails are placed on top.
Vertical posts are mounted on the steps. Instead of balusters, horizontal rods or sheet plates such as plexiglass, plastic, veneer, triplex, etc. can serve.

Metal frame for staircase

Work plan:

Marking and cutting profiles, connecting frames under steps.
Concreting the structure.
Installation of stringers;
Equipping the back of the steps with corners.
Welding steps together.

Installation instructions:

The number of steps and their parameters are calculated.
To create the frame, a 10x10 cm profile and 4x4 cm corners are used. B in this case the pipe is used instead of a channel, as it is characterized by high rigidity.
Create a pedestal for a flat structure. The lower starting point for the beginning of the steps is located at the edge of the platform.

Attention! in case of installing a direct structure, a pedestal is not required, since it is important to take into account the starting points between the floor surfaces of the floors

This is how a profile pipe is mounted, welded to the lower platform, and at the top, using anchors, it is fixed to the wall surface. Then the pre-cut corners are welded.
The vertical parameters of the corners must have precise parameters, and the horizontal part of the products can protrude beyond the profile.
A gap is created between the steps and the wall surface for wallpapering.
Railings are welded to the side of the profile. Typically, the installation of railings is carried out with a distance of 10 cm from the edge. However, this will affect the narrowing of the stairs.

Screw designs

The pipe to create steps is cut into 22 cm sleeves.

To determine the number of elements, the height of the room is divided by 22 cm, that is, the dimensions of the riser.

From steel billet the gasket and console are cut. The gasket is welded to the console, then the resulting elements are attached to parts of the pipe (thickness 10 cm).

The steps are placed on the gasket using self-tapping screws. The tightness of the sleeves placed on the pipe should be increased. The formation of distortions and backlashes is excluded. If holes are formed with an inaccurate diameter, sealing rings are created.

Then the markings are made and the steps are assembled. It is important to provide for an overlap of approximately 5 cm. The length of the circle is no less than the wider part of the steps. All that remains is to assemble a single structure. Gaps are immediately drilled to secure future steps. The structure is primed.

Attention! The staircase railings can be made from iron; a 4x4 cm profile pipe is used for the posts, and a 2x2 cm pipe is used for the handrails.

Then you can build wooden handrails on top of the metal. Forged elements are usually used in railings. Hammer paint is used to paint the stairs.

After it dries, temporary steps are installed. This will require laminated pine boards. They need to be varnished. To attach the steps you will need 32mm wood screws.

Ladder

Structurally, the product looks quite simple. It forms an emphasis with bowstrings on the wall and floor surfaces. The slope of the structure is 60-75 degrees. The steps are placed at one interval of 35 cm from each other. To eliminate sliding properties, plastic or rubber tips are placed on its supports.

Materials for production:

A rectangular or round profile 2 m long. One rectangular profile 165 cm long (for steps). Typically, duralumin pipes with a thickness of 2 mm are used.
Nuts, bolts M8x70, washers.
Ideally, welding is used. In this case, screw connections are not needed.
4 plastic or rubber protection for the bottom of the supports.

To create an attached structure, you need to prepare steps. A profile whose length is 165 cm is cut into 5 identical products 33 cm long. Markings are made on two profiles 2 m long. Marks are placed so that there is a gap of 35 cm between them.

Provided that bolts are used to fix the steps to the base, it is important to create clamps from thin strips of metal, designed for bending pipes symmetrically to the shape and drilling gaps in them. In this case, an indentation of 1.5 cm is made from the edge. Gaps are made in the pipes of 2 m each. This is facilitated by preliminary marking. If welding is used for fixation, this aspect is skipped.

Steps are attached. Plastic or rubber tips are placed on the legs.

A staircase made of a profile pipe (not a round one) is durable and has good wear resistance. Unlike a wooden staircase, a metal staircase is more durable, although it may be heavier. The profile pipes themselves are already heavy, so you need to monitor the weight of the ladder as you work and try not to make it heavier, or better yet, reduce its weight. You can do this using the tips that can be found in this article.

Before starting work, it is necessary to make measurements, according to which the staircase will be built in the future.

What you need to know before starting:

Dimensions of the staircase opening;
Calculation required quantity material;
Turning the stairs;
Number of steps.

A staircase opening is a free space in the ceiling between the first and second floors. The very first thing you need to do is calculate the dimensions of this opening.

The amount of material is determined after all measurements, based on an already drawn up drawing.

Rotating the stairs is necessary when the dimensions or other features of the room do not allow the stairs to be placed straight, without bending at an angle.

It is also important to determine the number of steps on the future staircase. It is convenient to do this, knowing that the length of one step should be approximately 30 centimeters, the width from 90 to 125, and the distance between steps in height that is comfortable for a person is 15 centimeters. IN special cases The width of the steps can reach 180 centimeters, but such huge stairs will require additional fastening.

Also, when making calculations, remember that the average human step is 60 - 64 centimeters.

Installation of stairs from a profile pipe: drawing and necessary tools

Without a good drawing you can't do it quality stairs. If you have never dealt with circuits before, then it is better to seek help from a professional.

What is taken into account when drawing up a drawing:

Size of staircase opening;
Rotation, width and height of the stairs;
Number of steps.

You can also add future artistic decoration stairs if you plan to embellish it a little.

Calculating the inclination of the staircase steps will allow you to design a convenient and safe structure. Our information on how to choose the angle of inclination of the steps next material: .

After you have made the drawing and bought all the materials, you need to prepare everything necessary tools that will be needed during the work process.

Tools that will be useful when creating a staircase:

Welding and electrodes for it;
Grinder saw and discs for working with metal;
Hammer, drills;
Hammer.

In order not to get confused in the process of creating a staircase large quantities different parts, we advise you to number them.

Preparing a staircase frame from a profile pipe: tips

The frame is the basis of the future staircase, so it is necessary to think it through to the end, and then weld it with high quality.

Remember that when making a frame, welding will be required in any case. And that means the ability to handle it. If you do not have such skills, then you will have to resort to the help of a welding specialist.

The frame base is most often a pipe with a diameter of about 60 millimeters.

Frame manufacturing stages:

Calculate the number of steps, their height and width;
Proceed with the installation of the profile pipe. It will be mounted on wall anchors, which must first be installed. Additionally, the ladder must be secured on the other side using bookmarks.
Weld the corners to the pipe. Make sure that their measurements exactly coincide with those specified in the drawing, otherwise the final result will be of poor quality, and the staircase will be crooked and unsafe.
If necessary, railings can also be installed towards the end of the work.

How to weld a staircase from a profile pipe: further finishing

After you have finished making the staircase frame, you need to move on to its further finishing.

What to do after installing the frame:

Make steps;
Install railings;
If necessary, decorate the stairs.

Please note that a staircase made from a profile pipe is a heavy structure in itself. Therefore, you can lighten the weight a little by making the steps not from heavy metal, but from light wood.

With the proper approach, the combination of a metal frame and wooden steps will create an additional high-cost effect.

Railings can also be made of wood, but do not forget that the wood must be of high quality. As a rule, oak, beech or ash are used in the manufacture of stairs.

You can decorate the stairs at the final stage. For example, if you chose the option with wooden railings, then you can resort to artistic carving or burning.

Staircase to the second floor from a profile pipe: advantages and disadvantages

After you have become familiar with the process from a profile pipe, it is worth thinking about the advantages and disadvantages of such a design.

Advantages of stairs made of profile pipe:

Good strength and wear resistance;
Long service life;
Relatively fast production time;
You can create a staircase from a profile pipe alone, without the help of craftsmen;
Possibility to create a staircase of any shape;
Price for necessary materials not tall.

As you can see, such a staircase really has a lot of advantages. Its service life is noticeably longer than that of wood, and it is not as heavy as stone. However, there are also disadvantages.

Disadvantages of stairs made of profile pipes:

The metal frame weighs quite a lot, especially if the staircase is large. Because of this, when finishing the stairs it is necessary to use materials such as wood and plastic.
In order to create such a staircase, you need skills and experience working with a welding machine.

Do not forget that the stairs must be periodically treated with an anti-corrosion coating.

How to install a staircase from a profile pipe with your own hands (video)

A staircase made from a profile pipe is heavy and requires additional periodic processing. But the price for its production is noticeably lower than for other types of stairs, and its service life is longer. Properly manufactured homemade designs will serve for a long time.
