TRAPEZOID MECHANICAL SEAM
Rolled on site. Built for commercial strength. A 3" double-lock standing seam for commercial, industrial, and pre-engineered buildings, run to length right at your jobsite.
Rolled On Site. Built For Commercial Strength.
Our Trapezoid Mechanically Seamed Panel is built for commercial and industrial work, and we roll it right at your jobsite. It's a 3" tall structural panel and one of the most trusted profiles in the industry, for good reason: watertight seams, strength under load, and long runs without a splice.
The double-lock seam gets mechanically rolled shut after install, so water has nowhere to go. That makes it a go-to for low-slope and complex commercial roofs, pre-engineered steel buildings, and reroofs where the old system has given out.
We don't just sell panels. We help you build faster. Our mobile roll former can travel anywhere in the U.S. and run panels cut to length at eave height. No shipping delays, no damaged long panels, no piecing runs together.

Can my crew rent the roll former?

What is a double-lock mechanical seam?
After install, the 3" seams are rolled shut with a seaming tool, folding the panel edges together twice. That creates a tight, watertight joint that holds up on low-slope and complex roofs.

Yes. We stock the complete system: clips, closures, and accessories, ready to ship.
What kinds of buildings is it for?
Commercial reroofs, pre-engineered steel buildings, industrial warehouses, municipal and government buildings, and restoration and insurance jobs.
