Roofing Sheets
Overview
The Maxlong roofing profile is well recommended for any project. Each crest is designed with an anti-capillary groove, which interrupts the path water would otherwise follow through the side lap — protecting the roof against both crest corrosion and leakage.
Additional ribbing across the profile gives the sheet special strength, so it carries load confidently between purlins and resists foot traffic during installation. Sheets are roll-formed and cut to the exact lengths your roof requires, which removes end laps on most spans and reduces both waste and installation time.
Available in the full Maxlong colour range, and in bespoke colours developed on request.
