Why you can not cut corrugated board grinder

Decking is a sheet of steel that is coated with zinc. They also have a polymer coating layer that protects this building material from the harmful effects of the environment. Such material is easily bent, but after installation it is quite resistant to shock. He also retains his factory color for a long time.

The appearance of corrugated board resembles such an obsolete building material as slate. It has trapezoidal bulges and hollows of the same size. Thickness reaches 1 mm.

A hand-type angle grinder, which in our country was simply called a “grinder”, is often used for cutting metal, including corrugated sheets. However, many manufacturers of such a material categorically do not recommend this, since the heat generated from an electric tool can destroy the polymer layer. Despite this warning, many masters still use the grinder during the processing of corrugated board, since this tool is universal and easy to use. So why not cut corrugated grinder?

In order not to damage the edges of expensive building material, you must adhere to the basic rule: select the diameter of the cutting wheel based on the height of the embossed surface of the steel sheet.

If you use a small circle to cut corrugated board with a very deep relief, then in the lower corners the master will be difficult to get to the metal. Decking will have to be deployed, and this can lead to damage to the building material.

It is best to use a angle grinder with a large diameter circle and a thickness of approximately 1.5 mm for cutting profiled sheets. It should have special teeth that can bite into a galvanized sheet.

Also, the master should take care that the processed building material does not touch the ground. The operation to cut the profiled sheet is best done on a large table.

At the end of the article, we can conclude that a grinder can cut corrugated board. An experienced craftsman can cut any geometric shape on a metal sheet with a grinder. The main thing to remember is that during work the material being processed is very hot, sparks from friction of the disk against the metal fall on it, which leads to damage to the polymer coating. This in turn shortens the life of the metal sheet.
