Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel,aluminized zinc steel(aluzinc steel),SGLC,The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy.The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.
Shanghai AIYIA Industrial Co., Ltd. exports high-quality Super Galume steel coils/sheet to all over the world,such as Cincalum Zalutite, Algafort Zinc-alum, Aluzinc Zincalit, Aluzink Zinccalume, Cincalum Zintro-alum, Galvalume. Our aluminum and zinc plating have won high praise from customers for their excellent quality.

Performance difference between galvalume sheet and galvanized sheet
1. Resistance to atmospheric corrosion: Galvalume steel sheet is excellent, while galvanized sheet is good.
2. High temperature oxidation resistance:Galvalume steel sheet is excellent, and galvanized sheet is good.3. Processing performance: Galvalume steel sheet behaves well, and galvanized sheet behaves well.
1.Corrosion resistance:When zinc is abraded, aluminum forms a dense layer of alumina that prevents further corrosion of the corrosive material inside.
2.Heat resistance:Aluminum zinc alloy steel has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius.
3.Thermal reflexes:The heat reflectivity of Al Zn steel plate is very high, which is two times that of galvanized steel sheet.
4.Economical efficiency:Since the density of 55% AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is more than 3% larger than the area of the plated steel sheet when the weight is the same and the thickness of the gold-plated layer is the same.
