Galvalume® is an aluminum-zinc coated steel that provides extra corrosion protection. The cost of Galvalume® is about the same as that of galvanized steel.

Galvalume® offers the best qualities of aluminum-coated (aluminized) and zinc-coated (galvanized) steels. It has barrier corrosion resistance and heat resistance similar to aluminized and good bare edge galvanic protection and forming qualities like galvanized. So, Galvalume® will resist rust, the elements and fire while providing a sturdy and protective covering.

Currently, uses for Galvalume® include car mufflers, standing seam roofing, tubing for fences, greenhouses, steel buildings and much more. Galvalume® offers excellent cost-effectiveness, which we pass on to our customers. 35 year perforation guarantee backed by U.S. steel mills.


Galvalume®, by virtue of its combined protection of aluminum and zinc, has at least twice the service life, in most atmospheric environments, of conventional galvanized steel with the same coating thickness.

In a series of exposure tests performed over a 13-year period by Bethlehem Steel, Galvalume® steel was found to outlast galvanized by:


Galvalume® steel resists intermediate and high temperatures far more effectively than galvanized steel.

Specifically, Galvalume® steel shows no discoloration up to 315°C (600°F) during continuous or intermittent exposure over a prolonged period. Above this temperature, some discoloration does occur and roughening of the surface is possible. Neither this discoloration nor roughening, however, reduces Galvalume®'s resistance to rust. Galvalume® maintains its rust-resistance up to 675°C (1,250°F).

Florida testing approval for high wind velocity up to 150 mph
