1060 H18 3003 H24 Curtain Wall Color Aluminum Coil PE or PVDF Coating

Coated aluminum coil is a composite material made by applying multiple layers of organic coatings on the surface of aluminum coil after color coating and curing by baking. The aluminum alloy coil is surface-colored, so its performance is very stable and not easy to corrode. It can generally be guaranteed not to fade for at least 8 years. It has low density, high hardness, and a light weight.
Color coated aluminum coil has the advantages of both aluminum coil and organic materials. It has the advantages of high mechanical strength, good toughness, and easy processing and forming of aluminum coil, and has the good coloring, decorativeness, and corrosion resistance of organic polymer coating materials. It can be easily punched, bent, deep drawn, welded, and other processes. The products made are practical, easy to process, and durable.
