Prepainted Aluminum Roof Coil

August 22, 2022

Prepainted aluminum roof coil is widely used in the roofing of large public buildings, public workshops, prefab houses, and integrated houses. Its performance is very stable, it is not easy to be corroded, the surface layer can reach 30 years of quality after special treatment, and the weight per unit volume is the lightest among metal materials. Aluminum-magnesium-manganese alloys prepinted aluminum coil for roofing and exterior walls generally adopt the pre-roll coating (Coil Coated) process, which has the advantages of good color difference control, uniform paint film, high quality stability, and environmental protection. The type of coating generally uses PVDF fluorocarbon paint containing more than 70% of fluorocarbon resin.
