GALVALUME SHEETS

Galvalume is a roofing sheet that has a coating of zinc, silicon, and aluminum. All these coatings protect the metal and are the primary form of the steel made of oxidation.
It protects the base metal and sacrificial metal coating. It is designed with a combination of zinc, silicon, and aluminum. The composition using these 3 elements in a Galvalume coat is 50% of aluminum, and less than 50% zinc, with a very low amount of silicon.
