Dear visitors, dear friends!!!

In previous threads:

Do-it-yourself metal gate. How to cook by welding,
Welding at home. Do-it-yourself swing made of metal,

- You have already familiarized yourself with the technology of welding metals with an electrode and welding assembly, therefore, it makes no sense to touch upon such issues again in this topic. The only thing that will be discussed in this topic is the construction of a metal garage, its stiffeners, overlapping, covering the floor of the garage and choosing a place.

Initially, we ask the question:

How to build a garage

What kind of garage to build is an individual choice for each of us. For example, you can build a metal frame for a garage and make the inner lining of any choice, from the following material:

drywall fiberboard

chipboard trapezoid rail

laminate ceiling wood slat

The choice of material for interior decoration on sale is large and each of us chooses the material at our discretion.

The construction of a metal garage is, as you understand, the availability of the necessary metal, as well as other building materials. A variety of material has its own name and not every one of us knows the name of any particular material. I think that initially we need to familiarize ourselves partially with the range of metal profiles necessary for the construction of a garage.

Metal profile for garage

When working with welding, welding of any structure, the name of the materials is simply necessary to know. Here are presented exactly the products from which it is quite possible to build a metal garage frame.

pipe profile steel reinforcement steel

round (hollow) steel pipe

channel steel steel I-beam

one-tee steel beam (tavrik) steel angle unequal

It was the scraps of this material that were used in the welding of metals for the construction of the frame, more precisely, the trimming of the listed metal profile. Before construction, you need to decide on a place for a garage.

Place for a garage

A place for a garage is chosen in the backyard (private house, cottage), taking into account the preliminary planning of the land, that is, it is necessary to take into account where the bathhouse, house and other buildings will be built.

Further, preparatory work is being carried out for pouring the foundation for the garage. During construction, it is necessary to approach from an economic point of view. T0-is in this example, it was decided that the foundation of the garage should not be completely poured along its perimeter, but only concrete small supports should be made at the corners of the garage structure and at the center of the length of each side.

floor in the garage

In the beginning, I will describe how the concrete supports were made (photo 2):

A small hole was dug in the ground, concrete was poured into it, a metal cylindrical container without a bottom was installed on top of the concrete, concrete was poured into this container and then, after the concrete hardened, a lid was welded to the container from above.

If you just visually pay attention to the design of the garage support (photo 2), it may seem at first glance that the corner of the structure is installed on an empty metal tank, but in fact, the tank is filled with concrete (as already mentioned) in an inseparable bond with the base concrete in the ground.

How convenient is such a support structure for each corner of the garage? This design is convenient in that the base or floor of the garage in the future is easy to set up on an exact horizontal plane using the building level.

building level

During the construction, tools were also used, such as:

construction angle

This photograph clearly shows (photo 3) how the corner of the structure was welded to the support post, the sides of which were butt welded together.

The intermediate distance between the support posts is lined with masonry, half a brick. Along the perimeter of the garage, on both sides, there are ventilation holes. This is done in order to ensure that the floor (flooring material from the boards) is constantly in a dry state.

Along the length of the perimeter of the garage, support posts made of a profile pipe were welded, and stiffeners were welded between the corners.

garage roof

For additional structural stability, a slope was welded between the post and the lower crossbar (photo 6).

The upper crossbars along the perimeter of the roof are welded from the corner (photo 6). The building material for the roof are metal beams, such as:

round steel pipe (hollow),
steel channel.

As you can see from the photographs, the construction as a whole is built from rusty metal waste of the metal profile (photo 7; 8; 9).

Initially, various rusty metal profiles were assembled, and in the end, all this came in handy during the construction of the structure.

If you are not a supporter of heavy capital brick or small block garages that require a solid foundation and roof, then you can opt for a metal one designed for one car. Such a construction can be completed in a fairly short period of time. At the same time, the fastening of the main elements can be performed both by welding and using bolts with nuts.

In this article we will tell you how to make such a garage, show drawings, photos and video materials.

Foundation

It is believed that a metal garage is a lightweight structure that requires a purely symbolic foundation (only deepening it around the perimeter by only 20-25 cm and about the same width). Another option is to pour a concrete slab reinforced with a mesh, which will simultaneously be both a foundation and a subfloor, or lay factory floor slabs on the ground.

However, in any case, the following conditions must be observed:

the top of the foundation or base slab should be 15-20 cm above ground level so that water does not leak during rain or snow melt;
the surface of the foundation or slab must be strictly horizontal;
at the corners of the foundation or a solid slab, be sure to concrete small pieces of reinforcement, to which the frame will be welded in the future.

It is better to pour the foundation at a time so that it forms a single monolithic element. Since when creating a strip foundation, not too much concrete is required, you can use a concrete mixer and make concrete directly at the location of the garage.

Manufacturing

The dimensions of the garage for storing one car are 3.3 by 5.5 (or 6) meters. At the same time, if you plan to conduct insulation (for example, with mineral wool), each of the indicated dimensions should be increased by 15-20 centimeters.

The frame can be welded from a metal corner of a large section - this will make the structure rigid and durable. All work is carried out immediately at the installation site.

The frame assembly process consists of the following steps:

The lower frame is welded first (do not forget to weld it to the rods protruding from the concrete at the corners of the structure so that the reinforcement outlets are inside the structure).
Then the vertical corner posts are welded.
In the front part, two side posts for the gate are installed and fixed.
All fixed racks in the upper part are interconnected by the upper frame.
After that, it is necessary to carry out the load-bearing elements of the roof, while:

with a shed roof, the racks of the front side should be higher than the others (the slope of the roof will be towards the back wall);
with a gable roof, you will also have to weld triangular truss structures and weld them to the upper frame.

Intermediate racks along all walls are welded with equal spacing to enhance the strength and rigidity of the entire structure. In this case, the step of the rack depends on the width of the metal sheet, which will be welded to it as part of the wall.

If the sheets are overlapped, then the distance between the uprights should be 4-5 cm less than the width of the sheet.

The outer skin is welded to the finished frame or attached with bolts and nuts. It can be made from stamped sheets of galvanized or non-galvanized steel, as well as from corrugated board. In all cases, the thickness of the metal must be at least 1.2 mm.

On the roof, the sheets begin to be fastened from the overhangs to the ridge, observing the overlap of the upper sheets to the lower ones by 15 cm.

For a garage, you can choose any, but swing doors remain the most popular. They can also be welded right at the installation site in a similar way: first, the frame of the canvases is welded, then the metal sheathing is welded to it.

Warming

If the metal garage is not insulated, then when weather conditions change, condensation may begin to appear on its walls. The simplest option for insulation is the use of polystyrene foam boards. They can simply be glued from the inside to the skin between the frame racks.

Expanded polystyrene (styrofoam) has a big drawback: it burns. A garage, a fire hazardous room (there are canisters of gasoline, and a car with a full gas tank, and all sorts of other flammable automotive liquids).

It is better to use non-combustible heat-insulating materials as a heater (for example, mineral wool in the form of rigid mats), covering it from the inside of the room with any sheet material (OSB, chipboard, MDF, etc.).

Blueprints

The drawings below will help you decide on the size of the garage, roof configuration and type of gate:

For any car owner, having a garage is a must. To reduce construction costs and manage on your own, you should pay attention to metal structures. Even without much building experience, it will not be difficult to assemble a metal garage with your own hands. The construction process includes several stages: design and layout, foundation construction, installation of a garage box and insulation of internal surfaces.

Before starting construction, you need to draw up a drawing of the garage and prepare the place where it will be installed. A metal garage can be of two types - stationary and on metal skids. The first option is considered more reliable and protected from car theft. To fasten the load-bearing parts of the box, either welding or bolts are used.

When drawing up a project, one should take into account not only the size of the car, but also the place for tool cabinets, a vise and a desktop. At the same stage, it is worth deciding whether there will be an inspection hole in the garage.

The foundation for such a garage is made of tape or slab. It should rise about 10-15 cm above ground level so that melt water does not flood the floor.

For construction you will need:

When all the tools and materials are prepared, they begin to clear the site. They remove high vegetation, stones, mark the boundaries of the foundation. With the help of a tape measure, square, twine and wooden pegs, markings are made for the foundation. The standard parameters of the base are 3.5x6 m, but may vary depending on the project.

Building a foundation for a garage

The area of the slab foundation usually exceeds the area of \u200b\u200bthe building by 20-40 cm around the entire perimeter. Such a base is suitable only for those garages where there is no viewing hole. If a pit is necessary, the foundation must be tape.

According to the markings, they dig a pit with a depth of 40-50 cm. The bottom is covered with a layer of sand, then comes a layer of crushed stone or gravel. A two-level lattice is knitted from reinforcing bars and laid on crushed stone. The edges of the grid should not touch the walls of the pit. They knock down a formwork 30-40 cm high from the boards and expose it along the inner perimeter of the pit. Outside, the formwork is reinforced with timber spacers. The height of the reinforcing cage should be 2-3 cm below the height of the formwork.

In each corner of the foundation, you need to make additional fasteners for the garage frame. To do this, pieces of reinforcement with a cross section of 16 mm are inserted at the corners between the cells of the lattice so that they rise above the surface of the foundation by about 30 cm. Then a concrete solution is prepared and the foundation pit is poured. To avoid cracks and delamination of the foundation, pouring must be done at a time. The base should dry for about a month, at first the surface should be periodically moistened and covered with a film from the sun's rays.

An inspection hole is dug simultaneously with a trench under the foundation. The width of the trench should be at least 20 cm, the depth should be from 50 cm. The formwork from the boards is upholstered with a film and installed on both sides of the trench. The height of the formwork above the ground is about 20 cm. The bottom is covered with a sand-gravel cushion, and a reinforcement frame is mounted on top. In the corners, vertical bars are set to a height of 30 cm from the surface of the foundation. Mix the ingredients for the solution and pour the formwork. The top of the foundation is covered with a film and periodically moistened with water.

An inspection hole is dug at a distance of at least 1 m from the walls of the garage. Its width, taking into account the thickness of the walls, is 1 m, the length is equal to the length of the car, but may vary slightly. The depth of the pit depends on the height of the owner of the machine, but on average it is 1.5 m. While the foundation dries, the walls of the pit are laid out with bricks or poured out of concrete.

To make a solid and even floor in the garage, the platform inside the foundation is leveled, covered with sand and well tamped. A waterproofing film or roofing material is laid on top, a reinforcing mesh is laid and the concrete mixture is poured. Using a long rail, the solution is distributed over the site and the surface is leveled.

Step 1. Installing the supporting beams

After the foundation has dried, you can begin to install the frame. First, the lower frame is welded from 4 large-section metal corners and at the same time welded to the reinforcing bars protruding from the foundation. The rods must be located inside the perimeter. Pipes for vertical beams are cut to the height of the walls, placed in the corners and temporarily fixed with spacers. If the roof in the garage is single-pitched, the front struts are made 20-25 cm higher. Next, the support struts are leveled with a plumb line and welded to the lower frame, and then the structure is fastened at the top, connecting the struts to each other with corners.

Step 2. Installing jumpers

To strengthen the frame around the perimeter of the garage, additional racks from the corner are attached. The distance between the uprights should not exceed 1-1.2 m. Reinforcing bars are welded diagonally as stiffeners. You can fasten the jumpers with bolts, replacing the diagonal rods with horizontal corners or shaped pipes. In the front part of the frame, support posts for the gate are installed on the sides. There must be at least 20 cm between them and the supporting vertical beams. The gate posts are reinforced with pieces of reinforcement, welded at an angle to the lower and upper frames.

Step 3 Mounting the roof

The roof for a metal garage can be single-pitched and gable. For the installation of a shed roof, the front and rear of the frame are connected with steel corners, which are reinforced with jumpers every meter. For a gable roof, longitudinal beams from a profile pipe are installed above the upper frame. Then, triangular rafters are mounted from the corner and fixed to the ceilings with a step of 1 m. After that, all the rafters are connected with one continuous corner, welding it along the very top of the structure.

The finished frame must be properly sheathed with steel sheets. Sheathing can be fastened by welding or bolts. If corrugated board is used as sheathing, fastening is carried out in the second way, since welding destroys the protective polymer coating. Sheet steel is first cut with a grinder to the size of the walls, and then spot welded to the posts and lintels. On the roof, the sheets are overlapped by 15 cm, starting from the bottom and leaving overhangs on the sides of the garage. Finishing the skin, be sure to weld all the joints. If fastening is done with bolts or self-tapping screws, the side sheets are also overlapped, fixing the joints along the entire length.

Gate installation

The frame for the gate is assembled from a corner, strengthened with horizontal and diagonal jumpers, spacers from rods are welded at the corners. After fixing the hinges, the frame is ground, wiped from dust and coated with an anti-corrosion compound. Then the gates are painted, and when the paint dries, the doors are sheathed with metal. Having installed the lock, bolt and handle on the door leaf, they are installed in the opening and fixed on hinges.

Any non-combustible material is suitable for thermal insulation of a garage room. It is more convenient to work with slab insulation: the slabs are adjusted in size and inserted between the support posts. When using mineral wool, it is impossible to strongly compress and crumple the corners of the material, this increases the thermal conductivity of the material. To completely isolate the cold bridges, an aluminum profile is installed between the lower and upper frames along the perimeter of the walls at regular intervals. Having filled the space between the support posts with insulation, a second layer of mineral slabs is laid, thrusting them behind the profile.

If the garage is insulated with foam plastic or polyurethane foam boards, the material is solidly glued to the wall surface. The joints must be very tight, all gaps and holes are blown with foam. From above, the insulation can be covered with plaster or sheathed with sheet materials - galvanized, plywood, chipboard and others. After the walls, the ceiling is insulated using the same materials, and if desired, the gate can also be insulated.

Ventilation device

To avoid the formation of condensate on the walls and the accumulation of harmful gases and fumes in the garage, supply and exhaust ventilation is necessary. Making it yourself is quite easy. A through hole of small diameter is cut in the back wall at a distance of 15 cm from the ceiling. A piece of ventilation pipe is inserted into the hole and closed with a grate on both sides. Now, in the front wall at a height of 20 cm from the floor, the same hole is made for air flow. If the garage has a large area, supply holes are made on both sides of the opening, and exhaust symmetrically at the corners of the back wall.

Finishing

When the interior work is done. Getting to the outside of the garage. If the walls are plain metal, they must be primed and painted to protect against corrosion. The corrugated board coating does not need to be painted, therefore, outdoor work consists in installing ebbs, outdoor lighting, and windshields for the roof. To enter the car, a platform is concreted along the width of the gate opening, and it should be located at a slope.

To build such a structure, you will need a minimum of money and time. You can build such a structure in a few days. But if you have absolutely no experience in construction, in order to build a metal garage with your own hands, it will take more time, somewhere within a month. During operation, the garage does not require much attention. With proper and high-quality primary treatment with anti-corrosion materials, such a structure can last a long time.

Do-it-yourself frame metal garage is a fairly strong and reliable structure. The first step from which it is necessary to begin the construction of any structure is planning, sketching drawings. At this stage, it is necessary to determine the place of the future construction and the size of the building. To determine what size a metal garage should be, you need to measure the car in length and width with your own hands. Add space for tools and other purposes to the resulting numbers.

Many people prefer that the garage housed: a desktop, tool shelves, a rack for winter and summer tires. All this requires space and, accordingly, an increase in the size of a metal garage. Similar garages made of corrugated board are made 6 m long, 4 wide and 2.5 m high.

Base for iron garage

When you have decided on the size of the future building, and put rough sketches on paper, you can proceed to the next step. This stage is the most important, since the strength and durability of a do-it-yourself garage built from corrugated board depends on it. This very important stage of construction is the foundation. To build a garage with your own hands from a metal profile, you can use a tape, slab or columnar base.

The slab foundation is a monolithic reinforced concrete slab for the entire garage area. It will require large volumes of concrete and a huge amount of reinforcement. Therefore, this option is the most expensive and time-consuming. Also, for frame buildings, a columnar foundation is used. For these types of foundations, it will be necessary to drill or dig holes along all the walls, into which reinforcement frames are placed, and then concrete is poured. This option is simple and cheap.

To save time on constructing the foundation, building foundation blocks can be purchased. They will need to be placed around the perimeter of the future garage. After that, you can begin to build the frame of a metal structure. But the use of building foundation blocks requires the use of heavy equipment, an assembly crane. If there is not enough space on the site to move such equipment, then it is better to use other types of foundations.

The most common is the strip foundation. Due to the fact that the metal profile garage has a relatively small weight, a shallow version of such a base can be used. To do this, you need to take several steps.

How to make a base for an iron garage - a step by step diagram

Step 1: Marking and Digging a Trench

The building site needs to be levelled. Dig a ditch 50 deep and 40–50 cm wide along the previously marked line.

Step 3: Framing and Concreting

When the formwork is installed and securely fixed, it is possible to form a pillow under the base. To do this, coarse gravel and sand are poured into 20 cm. After that, the reinforcement is laid, which must be connected to each other. When the frame is formed, proceed to pour concrete. For faster and more convenient mixing, it is better to use a concrete mixer. When the concrete solution has hardened and become solid, you can begin to dismantle the formwork structure. After that, it is desirable to let the foundation stand and gain strength. As a rule, it takes 1-2 weeks. If an inspection hole is needed inside the garage from corrugated board, then it must be made in the length of the car, and the width, as a rule, is 80–100 cm. The depth depends on your height. You will need a margin 20–30 cm deep. This level is necessary for filling sand with gravel (10–20 cm) to the bottom and creating a screed (10–15 cm). After the floor of the viewing hole is ready, you can begin to lay out the brick walls.

Metal profile garage - frame formation

When the foundation has gained strength, you can proceed with the installation of the garage frame from the metal profile. To do this, you need metal corners of 2 mm. You need to start by laying around the perimeter of the foundation. These corners are welded to the anchors by spot welding. After creating the bottom frame, proceed to install the racks with an outward angle. We advise you to install them every 2 meters around the perimeter of the metal profile garage. You should always start from the corner of the structure.

Racks are welded to the anchors and the lower horizontal frame. After these works, begin to form the upper frame. Upon completion, you will additionally need to create a horizontal belt at a height of 125–150 cm, which must be welded. This will give more structural strength. When the main frame of the metal profile garage is designed, we proceed to the installation of the roof rafters. To do this, you must first cut the corners and weld them to the racks. To strengthen the rafters, you will need to weld horizontal metal slats to them.

After all these activities, we can say that it is formed from a metal profile. Now start covering the walls. This can be done in two ways. The first is welding 2 mm metal sheets to the frame. This must be done by placing the sheets back to back. The second option is fastening the corrugated board with metal screws. Decking is recommended to be installed vertically. It is necessary to start fastening it with the lower wave to the extreme rack. Sheets must be overlapped. This will contribute to better water flow.

In order for the corrugated board to hold more firmly, a metal profile of smaller thickness (0.5–1 mm) must be fixed between the vertical posts. It is necessary to calculate that the distance between the vertical profiles is 50 cm.

It is better to cut sheets of corrugated board to certain sizes in the factory. This will reduce labor costs and increase the durability of the material itself. This is due to the fact that at the factory all sections are covered with a zinc layer, and painting is carried out with polymer paint. In addition to wall cladding, roofing can also be covered with corrugated board.

Metal garage - we insulate with our own hands

After the walls are already sheathed on the outside, we recommend that you insulate the “car house”. For this, solid basalt insulation is best suited, it will not settle over time. This material is good because it does not burn and does not support combustion. When exposed to fire, it does not emit acrid, life-threatening smoke.

After the insulation materials are installed, you can begin to sheathe the internal walls of the garage. To do this, you can use both moisture-resistant gypsum boards, and oriented strand or chipboard.

Owners of any vehicle need to protect it from the effects of external climatic factors or theft. One solution to this problem is to use a garage. These designs allow not only to limit the impact on the car, but also to comfortably carry out repair operations. Today, metal garages are becoming especially popular, as they are compact and quick to install.

Peculiarities

A metal garage is a metal structure that can withstand external physical and climatic stresses.

These structures are made using several types of materials:

Iron sheets. They are used to sheath the frame and create a solid system. The best option would be thick steel sheets that can withstand high physical exertion. But today you can find garages that are sheathed with thick profiled sheets. Such a structure is not always reliable, although the bearing capacity of the garage does not get worse from this.
Metallic profile. It is made in most cases from corners, shaped and round pipes. Together they form a monolithic system capable of withstanding various loads.

Installation of a metal garage can be carried out both on a specially prepared foundation and on level ground. Metal products in terms of strength are practically no different from brick structures.

Pros and cons

Many car owners prefer metal garages.

This is due to several advantages of these metal structures:

Fire resistance. The metal does not burn at all and does not support combustion, which makes it completely safe in the event of fires.
High strength. Structures made of thick and high-quality metal are difficult to crack. But these indicators are somewhat worse than those of monolithic brick structures.
Relatively low cost. The price of a garage depends only on the method of its manufacture and the quality of the metal. In most cases, these figures are much lower than those of classic monolithic buildings made of bricks or gas blocks.

A metal structure is not legally considered a monolithic structure. Therefore, these structures can be safely erected without specialized documentation.
Speed and ease of installation. It is possible to construct such a building even without a certain experience. There are several types of prefabricated metal garages on the market today. They only need to be assembled correctly by connecting all the elements according to the manufacturer's instructions.
Relatively light weight. If necessary, a steel structure building can be moved, which is impossible for monolithic structures.

But metal garages are not universal structures.

Such systems have several significant disadvantages:

The minimum level of thermal insulation. Metal does not retain heat well: it is rather difficult to work inside them in winter. Therefore, many experts recommend additionally insulating walls with various materials. Uninsulated garages quickly cool and heat up, which also leads to the formation of a large amount of condensate. It, in turn, has a bad effect on the metal of the structure and the car.
Inability to install electricity. This is due to safety precautions. Theoretically, current can be supplied inside, but if it is produced only by its own generators.

Low level of fire safety. The metal itself does not burn, but heats up very quickly, and the presence of cracks can lead to the penetration of fire from the outside into the building, with subsequent damage to the car and all other property.
The minimum level of protection. This applies to structures that are installed on a dirt or asphalt surface and are not attached to it in any way. Some craftsmen can simply raise the structure with a jack by prying one of the walls. Metal bases are also well destroyed by a grinder and special circles. Therefore, in terms of safety, a monolithic design is much better.

Constructions

The construction of any metal buildings requires preliminary calculations of all technical parameters. It is not always possible to do this without certain skills. But simple modifications can be calculated independently. Depending on the design of the structure, metal garages can be divided into several subspecies:

Factory buildings. Garages of this kind are in most cases collapsible and portable. To assemble such a product, you will need to stock up on only a few types of wrenches, a hammer, factory drawings and other auxiliary tools. Benefits include practicality and durability. But the cost of such a structure is much higher than an independent structure. The dimensions of garages often do not exceed a one-story building.

One of the varieties of these garages are used structures that can be purchased at various marketplaces.

Their prices are already much lower than for new modifications, and self-export from a specific place is also possible.

Garages built by myself. These buildings are distinguished by unique technical properties and dimensions. Some owners make two-story structures that allow them to be used as additional storage space. Many modifications are monolithic, as they are securely fixed to the concrete foundation. Please note that welding is already used here for the connection. This approach allows you to get a solid system that can withstand loads for a long time. But self-assembly of the garage requires already specialized skills in working with different tools. Therefore, it should be carried out only by specialists who are able to correctly calculate all the parameters.

Preparatory work

The construction of any structure involves preliminary planning. This will eliminate many unforeseen situations and create a strong and durable building. Installation of a metal garage involves the following preparatory operations:

The choice of a place for construction. It is desirable that the garage is located in a place convenient for the movement of the car. If you have a private plot, then you can install it directly near the road. In another case, it is desirable to ensure an optimal arrival of the vehicle. It is necessary to install metal garages remotely from a residential building and only on hills. If the structure is constantly heated by melt or groundwater, then it will quickly rust and become unusable.

Foundation preparation. Before starting work, it is desirable to remove the top layer of black soil, as well as level the soil. This will simplify all other installation work.
Design. There are no universal recommendations here. The dimensions of the garage should be such that your vehicle can easily fit inside. If you plan to repair this building or store spare parts, then the parameters must be increased to meet these requirements.

Purchase of building materials. To build a garage, you will need a lot of thick metal sheets, shaped pipes, as well as a welding machine, bolts, self-tapping screws and other fasteners. If you plan to make a warm building, then you need to take care of purchasing a certain amount of heat insulator (mineral wool and more).

Mounting

Building iron garages is a relatively simple operation. But doing it with your own hands is not always possible. It is better to carry out all work with several assistants who will not only help bring materials, but also hold the structure during assembly.

The installation of garages begins with the arrangement of the foundation. It is undesirable to install the structure only on compacted soil, as it will contribute to the development of corrosion processes.

For such a structure, several types of bases can be used:

monolithic foundation. A design of this type perfectly tolerates all kinds of loads. But for such light buildings, it is not effective to use it, unless the foundation has already been built for something.
floating foundation. Good and inexpensive option. For the construction of such a foundation, several reinforced concrete slabs should be laid on pre-compacted and leveled soil. Installation of these elements is carried out by a crane, which in turn increases financial costs.

Strip foundation. The best option for metal garages. Building it is relatively easy. Initially, a channel is dug around the entire perimeter of the future building. The depth of the trench should not exceed 50-80 cm, as this is quite enough to withstand the light weight of the garage. After that, sand and gravel are poured into the bottom of the ditch, then everything is rammed. To improve strength, you can lay a granite stone here, and then fill it with a liquid cement mortar. Formwork is mounted on top, which is already filled with concrete. The height of the support is selected individually depending on the needs of the owner and the characteristics of the soil. But it is not recommended to make formwork that is too high, as this will increase the volume of materials for leveling the floor.

The metal structure construction algorithm consists of the following successive steps:

Frame construction. Outwardly, it resembles a parallelepiped, the walls of which are reinforced with additional racks. From the side where the gate will be located, a kind of internal frame is being built for these structures. Pipes are connected to each other by welding. If you do not weld the profile, but fasten it with bolts, then over time small fluctuations will appear and the structure will not be so strong.

It is desirable to additionally strengthen the profiles with stretch marks, metal corners and other similar elements.

The roof can be single or double pitched. If the second option is preferred, then it is necessary to ensure the possibility of attaching metal structures to the main frame. The construction of this system involves the manufacture of frames in the form of triangles, and then attaching them to the main supports. The logs are connected to each other with the help of metal jumpers.

Sheathing. This step is relatively simple. Start wall cladding from one of the corners. To do this, a metal sheet is welded or screwed to the frame. The second option is used together with profiled sheets, which can be selected for any size of the building. When sheathing, it is important to completely eliminate the presence of any cracks. Therefore, you need to monitor the density of the joints, where they are formed. If a profiled sheet is used, then it is laid on top of each other. In the case of welding, the joints are qualitatively welded or covered with additional metal plates.
