55% Alu GL COILS galvalume steel sheet is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.5% zinc and 1.5% silicon solidified at a high temperature of 600°C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal An alloy .The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
