Overview

Pierced-fix sheeting

Roofco's Corrugated is the traditional circular-crest profile, roll-formed to a 762 mm cover width. The steeper minimum pitch (10° for runs up to 15 m) makes it well suited to traditional residential pitches. A 610 mm cover width variant is also available; verified technical data here is for the 762 mm sheet.
