Characteristics of aluminum zinc plate
1. Thermal reflectance:
Aluminized zinc steel plate has a high thermal reflectance, 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, which can withstand the high temperature of more than 300 degrees Celsius. It is very similar to the high temperature oxidation resistance of aluminum coated steel plate. It is often used in chimney tubes, ovens, illuminators and
fluorescent lampshades. Corrosion resistance:
The corrosion resistance of aluminum coated zinc steel coil is mainly due to the protection function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of alumina, which prevents
further corrosion of the corrosion-resistant material inside.
Because the density of 55% Al Zn is smaller than that of Zn, the area of Al Zn steel plate is more than 3% larger than that of galvanized steel plate under the same
weight and thickness of gold plating layer.
4. easy to paint
There is excellent adhesion between the aluminized zinc plate and the paint, which can be painted without pretreatment and weathering treatment.
The coating adhesion of the
gold-plated aluminum zinc steel plate is relatively good, so it can also be directly coated on the advertising board and general use board without pretreatment such as weathering.
5. The aluminum zinc plated steel plate has a gorgeous silver white
6. Aluminized zinc steel plate and galvanized steel plate have similar processing performance and spraying performance.
