This is an aluminum galvanized steel most idally mixed in the ratio of aluminum and zinc.
Coating composition is 55% alumum in weight ratio (80% surface volume ratio),43.4% zine, and 1.6%, silicon, so that long-term corrosion resistance and heat resistance of aluminum and galvanic behavior effect of zine may exert their characterisrics most. Namely, this is a product that ideally combines both characterisrics of aluminum steel sheet and galvanized steel sheet.

silicon 1.6 1
Galvalume is three toi six times more corrosion resistant than zinc coated steel sheet of the same thickness. SuperGalum is backed by a 20-year warrantee for residential use.
The capacity ratio of the aluminum in the coated layer of Galvalume is hight at over 80%, Galvalume will withstand a prolonged temperature of 315 degress Celsius wirhout discoloration or oxidization.
Galvalume is highly energy effcient, with superior heat reflectivity and low heat consumption.
Galvalume is availavble in a delicate light silver spangle, so it is appropriate for decorative use.
Available in widths of five feet (MAX 1600), Galvalume reduces the loss and suite to duct and construction.
Paint is highly adhesive to the coated layer of Galvalume steel sheet, compared to galcanized steel plates.
The workability of Galvalume is similar to that of galvanized steel sheet, Its ability to suppress fine cracks on the coating layer enhances the durability of the treatment area.
