A barn is a building necessary in a private courtyard in a city and in a village. You can’t do without it in the country. Gradually, more and more tools, equipment, building materials are accumulated that need to be stored somewhere. A reliable shelter for all these things is a metal shed. If you know how to weld metal, it will not be difficult for you to make it yourself. It is obtained at a cost approximately equal to wood, and much cheaper than brick.
Iron barn construction technologies
There are capital metal sheds, and there are prefabricated ones. A capital iron shed may have a concrete floor, which is poured onto a prepared base, or maybe a wooden one. If a floor is planned from boards, the upper trim on which it will rest is made of a thick-walled profile pipe with a section of 60 * 60 mm or 60 * 40 mm or a corner with a wall thickness of 4-5 mm or more. Floor logs are attached to the strapping. They can also be metal, or they can be wooden.
In a small metal shed, you can also make a floor without a log. To do this, the harness can be made from a corner with a thickness of about 4-6 mm and a side of at least 10 cm. Use the corner shelf as a support for the boards. Only the board must be at least 40 mm thick. Large spans may require additional support. It can be made from a profile pipe of the appropriate section.
A prefabricated / collapsible metal shed consists of separately welded wall frames that are bolted together. Sheathing is most often a profiled sheet, which is quickly mounted and removed. The roof is made of the same material. You can install such a structure in the country in a couple of hours as well as dismantle it. They are placed for the season in unguarded dachas, and then they are either hidden under lock and key, or taken away to winter quarters.
There is another option for a prefabricated barn (they are also called a “hozblok”) – for those who do not want to mess with manufacturing. The industry produces ready-made kits that are assembled as a designer. There are Chinese-made options, there are domestic ones. The difference in price is not catastrophic 20-30%. And what you trust more, then choose. The assembly of one of the Russian iron collapsible sheds is shown in the video.

They were built from pipes of different sections and corrugated board, with a pitched roof. The dimensions of the shed are 6,5 * 4 meters, the height of the front wall is 2,5 m, the back wall is 2,15 m. The floor is made of concrete: in winter there will be nothing but a tool and a warm floor is useless.
Materials
Racks from round pipes with a diameter of 61 mm. They were chosen because they were on the farm. Strapping and intermediate racks from a rectangular pipe – profiled (60-40 mm and 40 * 20 mm). Wall thickness everywhere – 2 mm.
Consumption through pipes: round 32 m, profile larger section – 21 m, smaller – 156 m. Roofing decking MP-20 took 4 sheets 3,5 m long, and 4 – 4 m each, galvanized intake C8 – on the walls – 4 sheets 2,15 m each, 16 sheets 2,5 m each. This is a list of frame materials. And also fasteners and consumables for concreting:
- 16 bags of cement;
- 7 tons of gravel;
- waterproofing (1 roll);
- self-tapping screws, rivets, electrodes for welding;
- Wooden slats on the crate: 50 * 25 mm – 3 pcs. 6 meters.
The list of building materials is impressive. But at a price such a barn is still cheaper than a brick one.
Step by step construction
Start of work – marking the site. Pegs are driven in in the corners, diagonals are checked. If they are even, the twine is stretched, the installation sites of the racks are marked along it. In the marked places, shafts 60 cm deep were made with a drill. Pipes are exposed in them and poured with concrete mortar (M200).
First exposed and poured racks in the corners. When the concrete had set a little, fishing lines were tied to them – above and below. The rest followed suit.
The next step is welding the frame. A pipe 60 * 40 mm with a wall thickness of 2 mm is welded along the top of the pipes. Next, on one of the pipes in the corners, we mark the level of the floor. With the help of a hydraulic level, we transfer it to the rest of the corner posts. At these marks we tie the twine and transfer them to all racks. According to the marking, we weld a pipe 40 * 20 mm around the perimeter. By the same principle, we weld the crossbars in the middle: two are definitely needed. In order to freely drive a walk-behind tractor or a wheelbarrow in the door, they are made wide and high – 1,2 * 2 meters. The base of the metal shed has already been assembled with your own hands.
Next is the assembly of guides for the roof. We needed three farms 6,5 meters long. They were welded on the ground, then welded to opposite beams. After that, transverse pipe sections 40 * 20 mm (10 pieces) were welded. The frame of the metal shed is completely ready. The next stage is a primer – so that it does not rust.
Next, we started making concrete floors. First, formwork was installed. She was put outside the frame, stepping back 10 cm. They fixed the boards with pegs, propped them up with bricks so that the concrete would not move apart. Next, the foundation was prepared. Crushed stone and broken bricks were driven into the ground. They literally hammered it in with a rubber mallet. A piece of brick is placed on the ground, knocked until it is almost completely hidden. This makes the base more rigid, and an even uneven surface better adheres to the ground.
After that, beacons were put on a thick solution – even slats (board 25 * 50 mm), they were leveled along the fishing line: points were marked at opposite ends of the lower trim and a fishing line was pulled between them. After checking its horizontalness, beacons-slats were placed along it.
After the mortar had set on the lighthouses, they poured M-250 concrete (read about the grades of concrete and their composition here). They leveled the rule according to the exposed beacons and pipes of the lower trim, which were set at the same level.
Next, the installation of the cladding began – the profiled sheet. We started from the roof. So that the condensate that will form on the metal does not drip onto the head, first a waterproofing film was spread on the frame. It is laid with an overlap of one panel on another by about 10 centimeters, gluing them together with special double-sided tape (sold in the same place as waterproofing). It is better not to use ordinary plastic wrap: it lasts no longer than a few years – a maximum of -3-5.
Laying waterproofing starts from the bottom, moving up, gluing the panels. So it turns out that a drop that falls from above flows down to the very bottom. The strips were cut off longer than necessary and hung down a little at the edges (30 cm each) – so that water would drain from them and snow would not fall into small gaps with a side wind.
Next, the installation of the profiled sheet began. When laying any sheet material on the roof, it is important to set the first sheet correctly. Then everything will go on easily. Therefore, we carefully measure all the protrusions with squares, rulers, etc. When the sheet is exposed, it is screwed with self-tapping screws. They are placed in a wave – in a ledge. So there is less chance that water will get into the hole.
With the lining of the sides, everything is about the same, only you have to cut the top sheets because of the slope. You put the first one exactly, then everything is like clockwork. The new sheet is leveled along the wave and fastened. It took about 20 screws to fasten one profiled sheet.
The door frame was welded from the same profile pipe 40 * 20 mm, hinges were welded on. When sheathing the door, it was removed and sewn up on a flat surface, hung already in finished form.

The metal shed was sheathed in the corners with a metal corner. It is set on rivets. It serves for decoration, and also closes small gaps that were formed during docking at the corners.
It turned out more than a spacious building – 26 squares. It can be used to store inventory, building materials, taking part under the workshop. This is if he stands on the site near the house.
For a dacha without security, a metal shed is a risky business, except to sheathe it with wood on top. Then you have to fasten the wooden sheathing to the frame (pictured below).

Not everyone knows how to use welding, but drilling holes and bolting two elements together is much easier. The video shows the entire process of assembling a decent-sized barn from a profile pipe with bolted connections. Welding used once: hinges are welded. There are no bolts here.
