Hot dipped ASTM A792 Al-zinc Coated Steel Coil Galvalume Steel Coil
Galvalume metal roof and siding panels are coated with a mixture of zinc and aluminum and siliconized coating to help resist scuffs and fingerprints better than a bare metal product. The mixture of zinc and aluminum protects the Galvalume metal against corrosion and rust, helping Galvalume typically last much longer than Galvanized steel. Galvalume also comes with a 25-year warranty, which is something that cannot be provided with Galvanized steel.
It is important to understand that Galvalume metal will start to rust and corrode overtime. It will age naturally, creating a unique, one of a kind metal. The more unpainted metal is exposed to the elements, the more it will take on a life of its own. A Galvalume roof is durable and can outlast asphalt roofs by years.

What Is Galvalume Used For?
The main purpose of galvalume is to protect steel from oxidizing (rusting), which compromises the integrity of the material.
It is used for many purposes, but the most common application is for outdoor metal paneling and metal roofs.
Galvalume metal VS Galvanized steel
Galvalume metal is similar to Galvanized steel, but uses a coating combination of aluminum and zinc rather than just zinc. The aluminum in Galvalume metal helps to better protect the panels against corrosion in certain environments compared to Galvanized. Galvalume is a high-performing metal option for high-temperature, high-precipitation, and marine environments. A Galvalume roof also provides a smaller, smoother spangle, which helps achieve a more uniformed design. Due to aluminum's qualities, Galvalume metal offers better surface protection than Galvanized, but is more vulnerable to scratches, blemishes or cut edges.
