You have seen that builders often use a conventional grinder to cut profiled sheets and metal tiles. I used to think that this is normal, that it should be so. But recently I was told the truth, which quite surprised me.
One friend of a professional builder said that it is undesirable to cut corrugated board with a grinder. Why? This will be discussed below!
- 1. If you cut the profiled sheets with an ordinary grinder, the top layer that resists corrosion is damaged. As a result, the material quickly becomes rusty. This negatively affects the service life of the corrugated board.
- 2. Manufacturers often cover the sheets with a special polymer layer. During the cutting process, sparks appear, which can easily melt this layer. Naturally, the appearance of the material suffers.
Actually, these are the main reasons why it is not advisable to cut the profiled sheets with an ordinary grinder.
One cannot help but wonder what, then, to use for these purposes?
1. From a conversation with a familiar builder, I learned that cutting the sheets is most optimal.
special hacksaw. Thanks to its use, no burrs or waves remain on the material, and the cut is very smooth.2. If you need to cut the corrugated board not in a straight line, then a hacksaw will not work. In this case, it is better to use jigsaw. It is clear that you will cut the sheets a little longer, but the protective layer will remain intact, which means that the operational life of the corrugated board will be maximum.
3. If you don't care what the edges of the cut sheets will be, you can arm yourself electric scissors.
- By using the slotted scissors, you will achieve an even edge. In addition, the coating of the sheets will not be affected.
- There are also die-cut shears. When bends and turns occur during the cutting process, then this tool fits perfectly.
4. Another popular method for cutting profiled sheets is using special drill bits. It is not easy to work with them, and therefore inexperienced builders and beginners are unlikely to cope with this. As a rule, attachments are installed in cordless screwdrivers or drills. With their help, you can get to hard-to-reach places.
What can I do to prevent corroded edges?
Regardless of which tool you choose, rust can appear on the edges. To avoid this unpleasant phenomenon will help the treatment of cutting sites with protective mastic or special compounds.
