Galvalume steel coil has more advantages than galvanized steel coil.
1. Heat reflectivity:
The heat reflectivity of galvalume steel coil is very high, which is twice that of galvanized steel coil. So people often use it as the material for heat insulation.
2. Heat resistance:
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is often applied in chimney tubes, ovens, luminaires and fluorescent lampshades.
3. Corrosion resistance:
The corrosion resistance of of galvalume steel coil is due to the protective function of aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
4. Economical and practical:
The density of 55% AL-Zn is lower than that of Zn by weight, the area of the of galvalume steel coil is more than 3% larger than that of the galvanized steel sheet with the same weight and the same coating.
5. Easy to paint
The aluminum-zinc steel coil has excellent adhesion to the paint and the paint can be coated without treatment.
6. Galvalume steel coil has a gorgeous silver-white surface.
