1. Heat reflectivity:
The heat reflectivity of galvanized steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as a 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 similar to the high-temperature oxidation resistance of aluminum-plated steel plate. It is often used in chimney tubes, ovens, luminaires and fluorescent lampshades. Corrosion resistance:
The corrosion resistance of galvalume steel coil is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
3. Economy:
Because the density of 55% AL-Zn is lower than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet with the same weight and the same thickness of gold plating.
4. Easy to paint
The aluminum-zinc plate has excellent adhesion between the paint and the paint can be painted without pretreatment and weathering.
The coating adhesion of the gold-plated aluminum-zinc steel sheet is relatively good, so it can also be directly coated on advertising boards and general-purpose boards without pre-treatment such as weathering.
5. Galvalume steel has a gorgeous silver-white surface.
6. The galvanized steel sheet and the galvanized steel sheet have similar processing performance and spraying performance.
