Cutting sheets on-site

man cutting metal roofing sheets

If necessary, we recommend metal sheets are cut whilst on the ground and resting face down on padded supports. Sheets should be cut using tools that produce little heat as this can damage a sheet’s coating.

For longer straight cuts we recommend a circular saw with a fine-tooth metal cutting blade that produces a cold cut. For smaller cut-outs and openings and for cuts that are not straight, a jigsaw or a reciprocating saw is recommended.

In other circumstances an angle grinder with a small tooth blade or disc is usually suggested although reciprocating nibblers which are widely used in the roofing trade also produce an excellent cut. Swarf should be removed with a brush to prevent eventual rust marking and scratches.
