Feature of cutting the corrugated board
Everyone will notice that the corrugated board is structurally similar to an ordinary sheet of tin, only corrugated. So you can cut with the same methods? Experts believe that this is not entirely true. After the corrugated board is not a bare sheet of steel, it is treated in special ways, covered with a protective layer of corrosion. When cutting, you need to try to keep this layer as much as possible so that the building material does not lose its precious properties.
Cutting of corrugated board is especially important because such an important coating is not able to withstand the high temperatures of , therefore we need mostly cold methods. This is the main stumbling block, from which the instrument is selected. Obviously, plasma methods, autogen or something like that should not be used. Also, with regret, it should be noted that the abrasive circle of the Bulgarian will destroy all the protective functions of the corrugated board in the cut-off area, and it will also blacken it badly. There is still a way out of this situation.
How to cut the corrugated board: the variety of the
tool Despite the complexity of the choice, the tool for cutting the corrugated board still exists, even in several variations. The first in the area of confidence is the usual hacksaw for metal .The work with this tool is done completely manually, which means it will take more time. Although many forces you will not spend, because the material can be cut easily. There are still disadvantages, except for time costs. You can not cut the sheet artistically, only in a straight line, and you will also need a special table for the convenience of the process to arrange the material.
For curved cutting, a tool similar in principle - jig saw - is suitable. And in this case the process can already be mechanized using a jigsaw. This is faster, and more convenient, and the degree of freedom is greater.
The next applicant is not found in every master, if he is not a professional roofer. We are talking about roof scissors. They also have two options - manual and electrical. Surely it never occurred to you that such strong sheets can be cut as a cardboard in a labor lesson. It turns out that it is possible, and indeed it turns out quickly and easily. However, when scissors for corrugated board are used, it does not always get a smooth edge, but if it then disappears under the next sheet when roofing, then it's not scary.
The last tool will still be a Bulgarian, but with a different cutting element. For this purpose, is used to cut the corrugated board .It is thinner and more delicate with the object of cutting. He is able to work thanks to his material and form. It is a thin enough disk from especially strong alloy, has on the end a teeth from the same alloy which will not break. So it turns out that cutting is not so unpromising, we even have a lot to choose from.
A few words about the cutting of corrugated board
What to cut the corrugated board, we have already figured out. It remains an open question how to deal with the longevity of the incised sheet. Even if you tried to preserve the integrity of the coating as much as possible, it will not be cut off at all. In our power only to reduce the area of damage, which, in fact, with the proposed tool is quite feasible. We can not restore the protective coating, but we can protect this place so that, for example, moisture does not get to it.
Here is the trimming process, the sheet turned out beautiful, without any damage, before installing the corrugated board the trimmed edge should be painted over with .It is best to do this with factory paint, which in most cases is given in the kit, or a can with it you can ask to provide you with a purchase. Then problems with color and texture, most likely, will not arise, and all the seams will be protected from the harmful effects of the environment.
