Choosing within this range

Every reference of this range states its profile, coating and useful width. Two points help you pick the right one.

Useful width and overlap

The useful width is the covered width once the side overlap is made. Count the number of sheets from it, not from the overall width.

Fixing and accessories

Use self-drilling screws with a sealing washer at the top of the ribs. Ridge caps, flashings and closures are ordered in the same coating.
