Galvalume coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon with the surface is characterized by smooth, flat and gorgeous starflowers, and the base color is silver white.The surface conductivity is also very good.
The normal service life of aluminum-zinc plate can reach 25a, and the heat resistance is very good, which can be used in 315 ºC high temperature environment; The coating has good adhesion to the paint film and has good processing performance, which can be used for stamping, shearing, welding, etc;

1 Thermal Reflectance:
The thermal reflectivity of aluminum-zinc coated steel sheet is very high, twice that of galvanized steel sheet. People often use it as heat insulation material.
2 Heat Resistance:
Al-Zn alloy steel plate has good heat resistance and can withstand the high temperature of more than 300 ºC. It is often used in chimney tubes, ovens, illuminators and fluorescent lampshades.
3 Corrosion Resistance:
The corrosion resistance of aluminum-coated zinc steel coil is mainly due to the protection function of aluminum. When zinc is worn, aluminum will form a dense layer of aluminum oxide to prevent corrosion resistant substances from further corroding the interior.
4 Economy
Because the density of 55% AL-Zn is smaller than that of Zn, the area of aluminum-zinc steel plate is more than 3% larger than that of galvanized steel plate with the same weight and the same thickness of gold-plated layer.
5 Easy to paint
There is excellent adhesion between aluminized zinc plate and paint, and it can be painted without pretreatment and weathering treatment.
AZ150 has the same corrosion resistance with Z275
