Your own garage or workshop often turns into a chaotic storage of things, where tools are mixed with spare parts, and finding the right part becomes a real torture. It is in such conditions DIY car racks become a salvation, allowing you not only to restore order, but also to free up valuable space for work. Self-production allows you to adapt the dimensions to a specific room and withstand loads that store-bought analogues made from a thin profile cannot.
Creating a reliable support requires careful consideration of load calculations and material selection, since the safety of your property and, more importantly, the integrity of the vehicle itself is at stake. In this article we will look at all the nuances: from the choice between a wooden beam and a steel corner to the final painting, which will protect the structure from rust in damp garage conditions.
Selection of materials and design of structure
The first step is always to determine the type of structure you plan to build. For storing wheels, jerry cans and heavy tool boxes, the ideal solution is metal framemade from a profile pipe or angle. Wood also has the right to life, especially if you want to save money or you don’t have a welding machine, but it requires careful treatment with antiseptics and is less durable in a humid environment.
When designing, it is important to consider bearing capacity shelves If you plan to store tires and rims there, the thickness of the metal should be at least 3-4 mm, and the pitch of the vertical posts should be minimized. For lightweight items, such as car chemicals or rags, you can use a thinner profile, but it is always better to make a safety margin.
⚠️ Attention: When calculating the height of the racks, take into account not only the height of the tallest family member, but also the possibility of installing the top shelves above eye level in order to use the space under the ceiling as efficiently as possible.
The standard depth of a garage shelf is usually 40-60 cm, which allows you to store most cans and boxes without drooping edges. The span width between the vertical posts should not exceed 1.5 meters when using a 50x50 mm steel angle, otherwise the shelf may bend under the weight.
Necessary tools and workplace preparation
To assemble a metal structure with high quality, you will need a basic set of metalworking equipment. The main tool, of course, is welding machine, since bolted connections in this case are less reliable and take up more space. If welding is not available, you will have to use powerful steel angles and bolts with a diameter of at least M10, which will complicate installation.
In addition to welding, an (irreplaceable) element will be angle grinder (grinder) with metal discs for cutting profiles and cleaning seams. Also prepare a building level, tape measure, marking pencil and protective equipment: mask, gloves and goggles.
- 🛠️ Welding inverter and electrodes (or wire for a semi-automatic machine)
- 📐 Construction level and long ruler for checking geometry
- 🔨 Hammer, chisel and metal brush to remove scale
- 🎨 Spray gun or brushes for finishing coat
Preparing the workplace involves having a level area where you will weld the frame. Often the assembly itself is carried out directly on the garage floor, placing wooden blocks under the structure to provide access for welding from all sides and to prevent the metal from sticking to the concrete base.
Before you start cutting metal, be sure to check the integrity of the discs on the grinder - cracks can lead to rupture of the disc at high speeds and injury.
Step-by-step instructions for assembling the frame
The assembly process begins with cutting blanks according to your drawings. First, four vertical posts of the same length are cut, then the crossbars for the upper and lower frames, and finally the elements for the shelves themselves. It is important to comply geometric accuracy, since distortion at the assembly stage will lead to instability of the entire structure.
First, the two side frames are welded. To do this, two vertical posts are connected by crossbars at the top and bottom. Make sure the angles are exactly 90 degrees using construction square. After welding the sidewalls, they are connected by long longitudinal jumpers, forming the main three-dimensional frame.
