- Trimming and Cutting Steel Panels
To cut panels across the profile:
The best devices for cutting steel across the profile are either hand snips or a nibbler. Carborundum blades on electric saws have a tendency to leave hot metal particles that can
either burn the painted surfaces or leave rust marks on panels and trim. The same is true of any filings left on the roof caused by the application of screws. Care should be taken to brush particles from roof surfaces after application.
To cut panels lengthwise:
Carefully mark where the panel is to be cut, and, using a straightedge, score deeply down the length of the panel with a sharp-pointed utility knife. Folding the panel along the score mark, and bending back again if necessary, should produce a clean break in the panel.
WARNING—Clean all metal shavings and particles off the roof to avoid rust stains.
