Galvalume Steel Plate sheet S250GB+AZ Galvalume Steel Sheet


galvalume steel sheet is a kind of aluminium-zinc alloy with 55% surface coating. The coating composition consists of 55% aluminum and 43.4% zinc and 1.6% silicon by weight ratio, respectively. The production process of galvalume steel sheet is similar to that of galvanized steel plate and galvalume steel sheet, which is continuous melting coating process. galvalume steel sheet with 55% aluminium-zinc alloy coating have superior corrosion resistance compared with galvanized steel plates of the same thickness when both sides are exposed to the same environment. The galvalume steel sheet with 55% aluminium-zinc alloy coating not only has good corrosion resistance, but also excellent adhesion and flexibility.

Product Description

1. Thermal reflectivity: the thermal reflectivity of galvalume steel sheet is very high, twice that of galvanized steel plate. People often use it as insulation material.
2, heat resistance: aluminum zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and the high temperature oxidation resistance of galvalume steel sheet is very similar, often used in chimney tubes, ovens, illuminators and solar lampshades.
3, corrosion resistance: galvalume steel coil corrosion resistance is mainly because of aluminum, aluminum protection function. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide that prevents corrosion resistance from further corroding the interior.
