Galvalume plate, as a high-performance corrosion-resistant alloy steel plate, is made by hot-dip plating process to evenly cover the surface of the steel plate with aluminum-zinc alloy. Its main components are 55% aluminum, 43.4% zinc and 1.6% silicon. This unique alloy ratio gives the galvanized sheet excellent corrosion resistance, heat resistance and good processing performance.

Advantages
1.Heat reflectivity:
The heat reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet
2. Heat resistance:
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius.
Corrosion resistance:
The corrosion resistance of galvalume steel coils is mainly due to the protective function of aluminum.
3.Economy:
Because the density of 55% AL-Zn is smaller than that of Zn, when the weight is the same and the thickness of the gold plating layer is the same, the area of the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet.
4.Easy to paint
Galvalume has excellent adhesion to paint and can be painted without pre-treatment and weathering.
5. Galvanized steel plate has a gorgeous silver-white surface.
6. Al-zinc coated steel plate and galvanized steel plate have similar processing performance and spraying performance.
