A corrugated metal roofing sheet is best cut with tools that have abrasive cutting wheels. The other power tools with toothed blades will not be very helpful.
Step 1 – Measure
Measure and mark the area on the corrugated metal roofing that has to be cut. Place the marker and the square blade side by side and drag them along the sheets edge.
Step 2 – Safety
Your safety is of prime importance. Hence, before cutting the corrugated metal roofing wear safety glasses, work gloves and a face shield.
Step 3 – Cutting
Align the cutting tool with the marked line on the corrugated metal roofing sheet. Use a 6 inch wheel. Turn the tool on and move through the marked line. Keep the wheel straight and avoid twisting it. If at some point you feel the cutting wheel is small replace it with another wheel with a bigger diameter.
Step 4 – The Final Step
The bur on the edge can be removed by dragging a grinder over it. This is how you can cut corrugated metal roofing sheet.
