Features of AZ30 Galvalume Steel Coils:

1. Corrosion resistance

The corrosion resistance of “galvanized steel coil” is mainly due to the protective effect of aluminum. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide that prevents corrosion-resistant substances from further corroding the interior. It is 3 times that of pure galvanized sheets; there are beautiful small sequins on the surface, which can be used as building exterior wall panels.

2. Heat resistance

The aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures above 300 degrees Celsius, which is very similar to the high-temperature oxidation resistance of the aluminum-coated steel sheet.

3. Heat reflection
The heat reflectivity of galvanized steel sheets is very high, twice that of galvanized steel sheets, and it is commonly used as insulation material.

4. Economy
Since the density of 55% AL-Zn is lower than that of Zn, under the same weight and the same thickness of the gold plating layer, the area of the galvalume steel plate is more than 100% larger than that of the electroplated steel plate. 3%.
