Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC. The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.From the point of view of the degree of coating, the Galvanized Steel Coil is mainly the zinc plated on the coating, while the coating of the galvalume Steel Coil not only has zinc, but also has an extra part of aluminum.Galvalume Steel Sheet (coil) has better atmospheric corrosion resistance.
