Color-coated aluminum coils are aluminum coils that have been cleaned, chromed, rolled, and baked, and then coated with paint in various colors. Color-coated aluminum coils are widely used in aluminum-plastic panels, honeycomb panels, insulation panels, aluminum curtain walls, blinds, rolling shutters, aluminum-magnesium-manganese roofing systems, aluminum ceilings, household appliances, downpipes, aluminum cans, and many other fields due to their light texture, bright colors, easy processing, and no rust.
Color-coated aluminum coils can be simply divided into the following categories due to different processing and usage purposes: Because of the paint applied on the surface, it can be divided into polyester (PE) coated aluminum coils and fluorocarbon (PVDF) coated aluminum coils; epoxy roller-coated aluminum coils. Of course, there are also cases where one side is coated with fluorocarbon and the other side is coated with polyester; there are even cases where both sides are coated with fluorocarbon; Because of the thickness of the coating, it can be divided into single coating (4-20 microns); double coating (25-28 microns); triple coating (35-38 microns); Because of the pattern on the surface, it is also called printed aluminum coil; because of different uses, it is also commonly called roofing material (aluminum-magnesium-manganese roofing system), ceiling material (made of aluminum alloy ceiling), home appliance board (used in the interior and exterior of home appliances, in line with EU Rohs standards), food material (food-grade chromium and roller coating, in line with US FDA standards), brushed board (surface brushed), etc.

1. Lightweight and strong: Color-coated aluminum coils are light in weight, but have high strength and good wind pressure resistance.
2. Corrosion resistance: Aluminum itself has good corrosion resistance, and the anti-corrosion layer on the surface makes color-coated aluminum coils more durable.
3. Easy to process: The surface of color-coated aluminum coils is flat and does not deform after shearing, which is suitable for various processing needs.
4. Rich color selection: It can be painted with a variety of patterns such as wood grain and stone grain, with realistic physical texture and fresh natural beauty.
5. Environmental protection: Color-coated aluminum coils are resistant to salt, alkali, acid and rain corrosion, will not corrode or produce toxic gases, are flame retardant, and are safer and more reliable during use.
6. Weather resistance: The paint pattern formed by joint coating and high-temperature baking has high gloss retention and good color stability. The polyester paint has a warranty of 10 years and the fluorocarbon paint has a warranty of more than 20 years.
7. Mechanical properties: Made of high-quality aluminum and other materials, using composite technology, it has bending and folding resistance and can adapt to various complex environmental conditions.
