Galvanized steel coil has many excellent characteristics: strong corrosion resistance, 3 times that of pure galvanized coil; beautiful spangles on the surface, which can be used as building exterior panels.
Corrosion resistance: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.
Heat resistance:aluminum-zinc alloy steel coil has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high temperature oxidation resistance of aluminum-plated steel sheets. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
Heat reflectivity:The heat reflectivity of galvanized steel coil is very high, which is twice that of galvanized steel. People often use it as a material for heat insulation.
Economical:Because the density of 55%AL-Zn is lower than that of Zn, the area of galvanized steel coil is more than 3% larger than that of plated steel coil with the same weight and the same thickness of gold plating.
