A fence around the house, a garage, a shed over the yard, an outdoor shower, you can enumerate for a long time examples of structures that we weld for our household needs. In 90 percent of cases, the material for such structures will be a profile pipe.
Why is the professional pipe so popular?
While the profile pipe is the most convenient material for welded household structures. A relatively low price when compared with other forms of metal, for example, a corner, a channel. Light weight - can be mounted without an assistant.
A square profile is easier to dock with each other in any position than, for example, round pipes or corners. Easy and quick to cut with a small grinder.
But the profile pipe has thin walls, there are also thick ones - 4 mm and more, but in the mass we use a thickness of 1.5-2 mm. Many people think, but how much will this thickness be enough? What if, in five years, the pipes will rot through and through and the entire structure will have to be dismantled. There is no need to worry, I will show an example of how long the professional pipe goes to through corrosion in extreme conditions and under constant load.
For more than 10 years, I have often been engaged in welding of cargo bodies and trailers at Kamaz trucks. Made from scratch or altered factory designs. In all designs, the most popular material was a 60 x 40 mm professional pipe, 2 mm thick.
Therefore, I have fairly accurate statistics on how long such a pipe goes to complete through corrosion. After how many years you have to repair, or completely redo these sides.
3 photos above - this is me doing welding repairs on the rotted side of the Kamaz trailer. Cut out all the unusable parts and welded in new ones. Notice how I make the connection of the new parts of the pipe with the old-cut at 45 degrees. It's stronger and nicer this way.
We came to the most important thing, such repairs are required 7-8 years after the start of operation of new structures. The new professional pipe in the design of the sides works this period in difficult conditions. Constant loads, abrasive, moisture and salt on the track. I have digested quite a lot of such through rusty sides. And all of them, on average, had about one term of work, plus or two years.
So fences, gates, sheds and other structures made of professional pipes in our area will stand up to through corrosion 2 or 3 times longer. If in extreme conditions and under load the professional pipe can withstand 8 years, then in ordinary conditions it will be enough for our age!
