Advantages
1.Thermal reflectance:
The heat reflectivity of aluminized zinc steel plate is very high, which is twice that of galvanized steel plate. People often use it as heat insulation material.
2. Heat resistance:
Aluminum zinc alloy steel plate has good heat resistance and can withstand a high temperature of more than 300 degrees Celsius. It is very similar to the high-temperature oxidation resistance of aluminum plated steel plate. It is often used in chimney tubes, ovens, illuminators and fluorescent lampshades. Corrosion resistance:
The corrosion resistance of aluminized zinc steel coil is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of alumina to prevent corrosion-resistant substances from further corroding the interior.
3. Economy:
Because the density of 55% Al Zn is smaller than that of Zn, the area of aluminum plated zinc steel plate is more than 3% larger than that of zinc plated steel plate under the condition of the same weight and the same thickness of gold plating layer.
4. Easy to paint
The aluminized zinc plate has excellent adhesion to the paint and can be painted without pretreatment and weathering treatment.
