AZ50 Zinc Coated Galvalume Steel Coil Aluzinc Metal GL Steel Roll

Galvalume steel coil introduction:

Aluminum zinc coated coil plate is made of cold-rolled steel plate as the substrate, and is solidified from 55% aluminum, 43.4% zinc, and 1.6% silicon at 600 ℃. It combines the physical protection and high durability of aluminum with the electrochemical protection of zinc. Also known as aluminum zinc coated steel coil.
The production process of aluminum zinc plating is as follows:
Uncoiling - cleaning - annealing - zinc pot - cooling - air knife - straightening - post-treatment - coiling
Thermal reflection
People use it as insulation material, and its thermal reflectivity is as high as twice that of galvanized steel plate.
Heat resistance
Aluminum zinc coated steel coils have good heat resistance and can withstand high temperatures above 300 ℃, which is very similar to the oxidation resistance of aluminum coated steel plates at high temperatures. Commonly used in chimney pipes, ovens, lighting fixtures, fluorescent lampshades, etc.

Galvalume steel coil material:

CGCC, DX51D,Q195,Q235

Galvalume steel coil application:

Corrosion resistance performance
The key to the corrosion resistance of aluminum zinc coated steel coils lies in the protective performance of aluminum. Once zinc is worn, aluminum forms a dense layer of aluminum oxide to prevent further internal corrosion.
economic
The density of 55% AL Zn is lower than that of Zn, therefore, under the same coating weight and thickness, the area of aluminum zinc coated steel plate is 3% larger than that of galvanized steel plate.
Easy to paint
The coating material on aluminum zinc plated steel plate has excellent adhesion and can be directly applied with tar on advertising boards and commonly used boards without the need for pre-treatment such as weathering.
