Owning a car requires not only driving skills, but also a responsible approach to the storage conditions of the vehicle. Metal frame garage It is one of the most rational solutions for a country house or a private house, as it combines strength, durability and relatively low cost of materials. Unlike capital brick buildings, metal construction is built much faster, often without requiring heavy construction equipment.
Self-construction allows you to significantly save the budget, eliminating the cost of labor of hired crews. However, the success of the event directly depends on the quality of drawings and compliance with the technology of mounting load-bearing elements. Profile tube high-quality flooring They are able to withstand severe wind and snow loads if the assembly is done correctly.
In this article, we will discuss in detail all the steps of creating a reliable shelter for your car. You will learn how to correctly calculate the amount of metal, what type of foundation to choose for a particular soil and what nuances of welding work can not be ignored.
Design and selection of materials
The beginning of any construction is inextricably linked with design. For metal-garage It is critically important to determine the dimensions in advance so that the machine is not only placed inside, but also there is space for opening doors and maintenance. The optimal width is considered to be a distance exceeding the width of the car by 1.5-2 meters on each side.
The basis of the design is a frame, which is most often assembled from a profile pipe of square or rectangular cross-section. For racks, metal is usually used with a cross section of 100×100 mm or 80×80 mm, and for jumpers and roof trusses - 40×40 mm or 60×40 mm. Wall thickness The profile must be at least 3 mm to ensure the required rigidity of the entire system.
For wall and roofing is ideal. flooring (Specialized sheet) with a polymer coating. This material is resistant to corrosion, sunburn and mechanical damage. You will also need fasteners: screws on metal with EPDM washers, which prevent leaks in the places of attachment.
- 📐 Accurate drawing with indication of all sizes and nodes of connection.
- 🏗️ A profile pipe of the appropriate cross-section for racks and runs.
- 🛡️ Folding with a sheet thickness of at least 0.5 mm for plating.
- 🔩 Fastening: electrodes for welding, screws, anchor bolts.
⚠️ Attention: When purchasing metal, consider the standard length of the whips (usually 6 or 12 meters) to minimize the amount of pruning and waste when cutting.
Preparation of the foundation and foundation
Metal garage, despite its lightness compared to brick, requires a reliable base. The choice of the type of foundation depends on the characteristics of the soil and the level of groundwater on the site. The most common option is ribbonIt distributes the load of the structure evenly.
The process begins with marking the territory and digging a trench depth below the level of freezing of the soil. In the trench is installed formwork, fitting the reinforcement frame and poured concrete brand M200 or higher. It is important to give concrete to gain strength for 28 days before the installation of metal structures.
An alternative is a plate foundation, which simultaneously performs the function of the floor. This is especially true if you plan to use the garage not only for parking, but also as a workshop. You can put it in the stove right away. viewing-holeif it is provided for by the project.
☑️ Preparation of the foundation
Waterproofing (usually a ruberoid in two layers) is necessarily laid on top of the foundation before installing the frame. This prevents the capillary lifting of moisture from the ground into the metal, reducing the risk of corrosion of the lower structural elements.
Frame assembly and welding
The construction of the frame is the most important step that determines the geometry and strength of the entire garage. Work is better to carry out on a level ground, collecting individual sections (walls, roof farms) on the ground, and then lifting them in a vertical position. The connection of elements is performed by the method electroarc welding.
First, the bottom bandage is welded, which is attached to the foundation by means of anchor bolts or welded to the embedded parts. Then vertical racks are installed, which are temporarily fixed by slanting to preserve the vertical. After installation of the racks, the upper runs and roof farms are welded.
- 🔥 Cleaning the welds from slag and rust.
- 🛡️ Treatment of all metal surfaces with primer.
- 🎨 Painting the frame with weatherproof enamel.
- 📏 Check diagonals to avoid distortions.
Particular attention should be paid to the quality of the welds. They should be boiled along the entire perimeter of the connection, without pores and cracks. After cooling, the seams are cleaned with a Bulgarian and covered with an anti-corrosion composition.
Do I need to reinforce the frame with slants?
Yes, the installation of diagonal slanting (wind connections) in the plane of the walls and roof significantly increases the stability of the frame to lateral wind loads. Without them, the structure can get deformed in a strong storm.
⚠️ Attention: Do not start the skin until you make sure that all the corners of the frame are exactly 90 degrees, otherwise the sheets of the flooring will be skewed.
Installation of walls and roofs
Skinning of the frame with profnastil begins with the installation of wall sheets. Installation is carried out on a single wave, starting from the angle opposite to prevailing winds (prevailing winds). Fixing is carried out by screws that are screwed strictly perpendicular to the surface in the lower part of the profile wave.
For roofing, sheets of greater thickness or a special roofing flooring with a high wave are used. Roof farms should be designed to handle the snow load of your area. The step of the crate under the flooring is usually 40-50 cm, but can be changed depending on the make of the sheet.
An important point is the device of cornice and gable overhangs, which protect the walls from oblique rain. All joints, endowments and adjoining to the gates should be sealed with special seals and roof sealant.
When screwing screws, do not pull them - the EPDM washer should only slightly press against the metal. Excessive force will crush the rubber band, and after a year in this place will appear to leak.
If the garage is planned to be insulated, then before installing the internal lining between the profiles of the frame, a thermal insulation material is laid, for example, mineral wool or polystyrene foam, necessarily with a vapor insulation film.
Installation of gates and wickets
In garages made of metal profile, swing doors are most often installed, since they are easy to manufacture and reliable. The frame of the gate is boiled from a profile pipe, a cross section similar to the racks of the frame, and sheathed with the same profnastiel. To ensure the stiffness of the flaps, diagonal slanting is welded inside the frame.
The hinges should be of high quality, with ball bearings, and welded to the gate frame and frame racks with observance of gaps. The gaps are necessary for the free opening and compensation of the thermal expansion of the metal in the summer. The standard gap between the doors is about 3-5 mm.
For ease of use, you can equip the gate with a shut-off system from the inside and a hinged lock from the outside. Automatic drives are also popular, which can be installed on swing or sectional gates, if the budget allows.

Internal arrangements and ventilation
After the completion of external work comes the turn of internal arrangement. Even if the garage is not heated, having ventilation is critical to preventing condensation, which is the main enemy of metal and the car. Natural ventilation It is organized through supply and exhaust holes located in different corners of the room at different heights.
For lighting, sealed lamps with a protection class not lower than IP54 are used. Wiring is laid in corrugated pipes or cable channels fixed on the walls. Sockets and switches should also be protected from dust and moisture.
Inside the garage, it is convenient to place shelves, workbenches and cabinets for tools. They can also be made from the remnants of the metal profile, creating a single style concept of space. The floor can be covered with special wear-resistant paint or rubber modular tiles.
Quality ventilation and corrosion-resistant treatment extend the life of a metal garage for decades, protecting both the structure and the car.
⚠️ Attention: When laying electricity in a metal garage, be sure to use grounding and differential machines (RCD) to protect against electric shock.
Frequently Asked Questions (FAQ)
Do I need to clean the metal garage?
Insulation is necessary if you plan to spend time in the garage in winter or want to avoid condensation ("dew point"). Without insulation, the difference in temperature inside and outside will lead to abundant moisture loss on the metal, which will accelerate the corrosion of the car and the structure itself.
What is the life of the garage from the flooring?
With high-quality anticorrosion treatment of the frame and the use of polymer coated profnatstival design life is 30-50 years or more. The key factor is the integrity of the protective layer of zinc and paint.
Is a permit required to build such a garage?
In most cases, if the garage is a non-capital structure (has no buried foundation and can be moved), a building permit is not required. However, local regulations may differ, so it is recommended that the local administration clarify this issue.
Can a metal garage be made to be broken?
Yes, if you use bolt joints instead of welded joints. This will allow the structure to be dismantled and moved to a new location, although such a garage will be less sealed and will require more careful control of the tightening of the bolts.
Which paint is best used for metal?
For outdoor work, alkyd or acrylic enamels for rust (3 in 1) are best suited, as well as specialized hammer paints. They create a durable film that is resistant to ultraviolet light and temperature changes.
