Anti-scratch Coated Aluminum Coil
Anti-scratch Coated Aluminum Coil
Performance and Usage
Anti-scratchcolor coated aluminum coil is made from the world's most outstandinghigh-performance polyester paints and high-alloy series aluminum. Because ofthe special processing way, it has excellent abrasion resistance andanti-scratch performance, and has all the advantages of PE coating formingperformance.
It can be widely used inairports, subway, shopping malls and other public places decoration, also beused in rolling shutter doors and windows and other products.
