What is the best way to cut corrugated board?

Many builders in the construction of the roof as a tool for cutting corrugated board use a grinder.

Why you should not use a grinder

However, this is not the best tool for this work and now we will try to answer why:

1. When cutting professional sheet the grinder raises the temperature and the anti-corrosion coating burns out. As a result of such damage, the sheet will begin to rust.
2. When a polymer-coated corrugated board is cut through a grinder, in addition to the problem described above, arising sparks can burn through the sheet. Corrosion processes can also begin in these places.

However, the grinder can be successfully replaced, since it does not belong to the only tool with which you can cut corrugated board.

How to replace it

The simplest way to do this is hacksaw. Her main advantage is speed and accuracy in work. In addition, you can use a hacksaw without much physical effort. True, there are negative points. For example, it is impossible to make a curvilinear cutting of profiled sheets with a hacksaw. This tool is used exclusively in the presence of the so-called "rifled" table.

Among the more complex tools can be distinguished jigsaw. It will help when performing curved cutting of corrugated board. It should be noted that there is no difference which instrument you will use - ordinary or electric. The main advantage of a jigsaw is that it can be used to cut sheets in any direction - both lengthwise and crosswise. When work is carried out using an electric jigsaw, then increasing the speed, you need to choose a reciprocating mode. The disadvantages of a jigsaw are very slight. Although it works slower than the grinder, it does not damage the coating of the profiling sheet, as the grinder does.

You can also use a circular saw, which is equipped with a fine tooth blade, to cut the profiled sheet. It can be considered the best option for cutting a profiling sheet. She can cut it both along and across, performing any cutting. True, certain skills are needed to work with this tool.

Therefore, we give some recommendations on how to cut a profiling sheet using circular saw.

• A conductor is made from a plywood strip measuring 150x30 cm. This will prevent scratching the paint on which the sheet is coated.
• After that, a groove is cut in the center along a strip of plywood.
• On both sides of the sheet, 3 points are marked for cutting, after which a conductor is applied.
