Aluminium-zinc alloy coated steel coil-galvalume / aluzinc coil export from VietNam - Nam Kim Steel

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.

Application
Buildings: roofs, walls, garages, sound insulation walls, pipes and composite houses, etc.
Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc.
Appliances: Refrigerator backplane, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc.
Agricultural: pigsty, chicken house, granary, greenhouse pipes, etc.
Others: thermal insulation cover, heat exchanger, dryer, water heater, etc.

Main Features

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.
