12/21 2022

Color coated aluminum sheet coil strip is a product made of aluminum coil as the base material after surface paint coloring treatment. The common coatings are fluorocarbon coating, polyester coating, etc.

Because of its good flatness, decoration, weather resistance, mechanization and environmental protection, it is widely used in aluminum plastic panels, industrial factory roof walls, aluminum louvers, composite panels, aluminum ceilings, pop cans and electronic products.

Color Coated Aluminum Coil

The coating selection of coated aluminum coils can be considered according to their application fields and project cost requirements. The coating can be divided into PVDF fluorocarbon, HDP high weather resistant polyester, PE polyester ect., according to the weather resistance and anti-corrosion performance of the coating.

Specification:
