Cold Formed Steel vs. Heat Formed Steel
Cold Formed Steel


Heat Formed Steel


Incorporates Warm Roll-Forming of prepainted Sheet Steel with clear coated edges.
In a recent study, U.S. Steel has demonstrated that warm roll-forming not only improves the formability of the paint film, but also improves the formability of the underlying metal coating.

Warm Roll Forming
It is believed that tension-bend cracking on the prepainted GALVALUME sheet could be virtually eliminated by using flexible paint systems and warm roll-forming practices.

The clear coating of panel edges protects the open edge, while the galvanic reaction is taking place, for a more permanent protection.

All of Fabco's The Metal Center steel coils are kept in the "Hot Box," a heated room which stays at 85 degrees or greater, all year.
