Galvalume Steel Coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal. of an alloy. Galvalume Steel Sheet has excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Steel Sheet; the surface has beautiful spangles, which can be used as building exterior panels. The corrosion resistance of "Galvalume Steel Coil" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
