Hot dipped galvalume steel coil has the following advantaged features.


1. Heat reflectivity:

Hot dipped galvalume steel plate has a high heat reflectivity, twice than the galvanized steel sheet, and is used 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 widely applied in chimney pipes, ovens, illuminators and fluorescent lampshades.
3. Corrosion resistance:
The corrosion resistance are effected from 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 sheet 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 Zn.
5. Easy to paint
The aluminum-zinc plate has excellent adhesion, which can be painted without pre-treatment.
