Roof Systems Classic Corrugated panel or sheeting (other names include traditional corrugation, galvanize profile etc.) is a profile that has been around for centuries and its timeless design and shape remain virtually untouched. Most popular with architects who want a traditional colonial look, this panel is both affordable and stylish in its own right.It can be roll formed in continuous lengths up to approximately 60 feet (limited by length of truck). It is also a structural panel that can span over open framing without the need for continuous deck support. Traditional applications have been almost every roof design imaginable as well as siding, hoarding and decking.
