Any fence involves an entrance, which, as a rule, has a gate and a gate. These fencing parts are usually the most expensive fence elements due to the complexity of their manufacture and installation. However, in this case, it is quite possible to save money by making a gate and a gate from a profile pipe with your own hands.
Advantages of a profile pipe as a material for gates
Profile pipe is one of the most economical materials with excellent strength, reliability and long service life. The cost of a professional pipe cannot be called low. However, the operational characteristics of the profile, as well as the possibility of creating structures from it without involving additional workers, fully compensate for the price of raw materials. This allows us to classify this material as the most acceptable for making gates from a profile pipe with your own hands.
All you need is a minimum ability to work with a grinder and welding, as well as some knowledge in the drawings.
Gate drawing
Before proceeding with the manufacture of the structure, it is necessary to first draw up a drawing of the gate from a profile pipe. First, thiswill allow you to accurately calculate the required amount of material. Secondly, it will guarantee correct installation, no distortions and a neat look.
Initially, it is necessary to carry out all measurements, on the basis of which the drawing is made. This event includes measuring the gap between the supports and calculating the area of \u200b\u200beach sash. By the way, even during the construction of the fence, it is necessary to place the pillars on which the gate from the profile pipe will be attached, at a distance sufficient for the passage of a car or other equipment. Also note that there is enough space left for the full opening of future doors.
Calculation features
When planning the gate, be sure to consider the windage of the material. If the structure is located on an area that is freely blown, the sashes are not recommended to be made too large and made of solid material. The fact is that in this case, the load on the frame will increase significantly, which means that the gate from the profile pipe will have to be strengthened. This will lead to an increase in the cost of the fence and more complex installation work. Therefore, it is preferable to use a building material such as mesh or grating.
What else needs to be done is to calculate the length of the wings so that they freely converge with each other. If subsequently the gate from the profile pipe will be sheathed with corrugated board, it is recommended to take into account the number of stiffeners on each leaf so that they do not cling to each other.
If the shaped pipe will serve as a frame for the sheathing web, make sure it fits freely into place.
Choice of material for the manufacture of gates
After the sketch of the future gate is drawn up, it is necessary to calculate the amount of material required. At the same time, as with the construction of any other structure, be sure to make a reserve of 10% for unforeseen circumstances.
Gate from a profile pipe can be made of material of different sections: round, rectangular or square.
The last two options are the most economical, they use slightly less raw materials than for round pipes. Another advantage of a square or rectangular profile pipe is that even a novice welder can work with this material, since it is much easier to weld gates from profile pipes with straight sides.
Besides, do not forget about the size of the pipe section. Mostly profile pipes with a section of 40 x 20 mm or 50 x 50 mm are used. However, do not forget about the wind load on the structure, in some cases it is required to use a larger section, for example 60 x 30 mm.
Gate manufacturing process
Of course, the first thing that is required is to prepare all the necessary tools and material for work. If the profile pipe is covered with rust, it must be cleaned and degreased, and then cut into pieces of the required length. Some builders immediately cover the material with a primer and protectivecomposition. But during welding, the product layer will be damaged, so it is better to carry out processing after installation.
Often the question arises of how to properly weld the gate from a profile pipe. The main thing is to observe the technology and sequence of welding work. Work must be carried out on a stable, flat area that is not subject to ignition. In this case, they use a protective mask or goggles, gloves, and choose a suit made of thick fabric as clothing.
Sash welding order
The whole welding process takes relatively little time and is carried out in accordance with the general technology of this work. Before welding the elements with a continuous seam, they are preliminarily tacked by spot welding. After that, the accuracy of the dimensions of the manufactured part is checked. If everything is done correctly, a welding seam is performed, which is subsequently ground.
First, the frame or frame of the gate is welded at the corners, while it is necessary to ensure that both leaves are in the same plane. Alternatively, a common frame is first welded, which is subsequently cut in the middle. This approach guarantees the accuracy of compliance with the required dimensions of the valves.
After the frames are made, they need to be reinforced. To do this, additional stiffeners from the same profile are welded to the main frame, and triangular metal plates are welded to the corners.
Another important point is the welding of the loops. First, the halves of these parts are attached directly togate leaves. The second halves are put on and, having attached the sash at the required height, the lower part of the hinges is welded to the supports. For this work, it is better to invite another person who will fix the gate in the desired position while tacking the hinges.
After all the welding work and grinding of the seams, the finished frame is covered with a protective agent. It can be varnish, mastic or paint. After that, you can proceed to sheathing the frame with the selected building material.
