These metal roofing sheets are best cut by tools that have abrasive cutting wheels. Toothed blades are not very effective.
- measuring tape
- 6 inch cutting wheel
- safety glass
- face shield
First of all measure the area that you want to cut.
Safety is the most important thing, no matter what activity you are doing. Always wear safety glasses, work gloves and a face shield when cutting things.
Now align the cutter to the marked line on the metal sheet. You should use a 6 inch wheel. Cut following the line. Avoid twists. If the wheel get’s used, then replace it.
Use the grinder to remove the bur on the edges of the metal sheet.
