AZ150 Aluzinc Coated Galvalume Steel Coil

Galvalume Steel Coil is also called Aluminum-Zinc Alloy Coated Steel Coil, Zinc-alume steel coil, aluminized zinc steel coil (alu-zinc steel coil), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ℃. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel coil/ 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 ℃. 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.

Mechanical Properties

Advantages of Galvalume Steel Coil/Sheet:
1.Corrosion resistance:When alu-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.

5.Easy painted:The galvanized sheet has perfect adhesion to the paint, eliminating the need for pre-treatment and weathering of the paint job.The coating material on the galvanized steel sheet has excellent adhesion and can be directly coated on advertising boards and common boards without pre-treatment such as weathering
