Hot dipped galvalume steel coil have the following advantaged features：

1.Heat reflectivity
Hot dipped galvalume steel plate have a high heat reflectivity, twice than the galvanized steel sheet, used as a material for heat insulation.

2.Heat resistance
Aluminum-zinc steel plate can withstand high temperatures of more than 300 degrees Celsius, which are widely applied in chimney pipes, ovens, illuminators and fluorescent lampshades.

3.Corrosion resistance
The corrosion resistance are effected by the protective function of aluminum. When zinc break, aluminum will create a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.

4.Economic practicality
The area of the galvalume steel plate is more than 3% larger than that of the galvanized steel sheet with the same weight and the same coating thickness because the density of 55% AL-Zn is lower than that of zinc.

5.Easy to paint
The aluminum-zinc plate have excellent adhesion, which can be painted without pre-treatment.
