Galvalume Steel…With the Corrosion Resistance of Aluminum​

Galvalume and Zincalum are steel, with a coating of aluminum and zinc. The result is a strong, durable metal with proven long term corrosion resistance.

The Galvalume / Zincalum Process…

The coating is 55% Aluminum and 45% Zinc and is applied to the steel sheet by a continuous hot dipping process. The Result… The coating shields the steel from moisture and contaminants while providing protection at scratches and cut edges. The process gives steel the unique combination of strength, long term corrosion resistance, with galvanic protection at cuts and bends in the material.

With more benefits…

Has a uniform, architectural shine that weathers evenly. - Resists fingerprints and smudging. - Its roll formed dry so there are no oils.


Galvalume was first manufactured in 1975 and has been thoroughly tested in many types of environments. Depending on the location (proximity to the ocean, industrial areas, etc.) of the installation, Galvalume and Zincalum have approximately nine times the longevity of galvanized steel.
