1. Flatness of aluminum coil: There is no composite high temperature indentation on the surface of aluminum coil. There is no residual stress on the surface of the aluminum coil, and it is not easy to deform after shearing.

2. Decorative properties of aluminum coils: Aluminum sheets for architectural decoration are widely used in building frames, doors and windows, ceilings, decorative surfaces, etc. because of their good corrosion resistance, sufficient strength, excellent process performance and welding performance. Such as various building doors and windows, aluminum profiles for curtain walls, aluminum curtain wall panels, profiled panels, checkered panels, color-coated aluminum panels, etc.

3. Weather resistance of aluminum coils: A dense and firm Al2O3 protective film is easily formed on the surface of aluminum and its alloys. This layer of protective film will only be destroyed under the intense action of halogen ions or alkali ions. Therefore, aluminum has good resistance to atmospheric (including industrial atmosphere and marine vapor) corrosion and water corrosion. It can resist the corrosion of most acids and organic substances. The corrosion inhibitor is used to resist the corrosion of weak alkali solution; the corrosion resistance of aluminum alloy can be improved by adopting protective measures.

4. Mechanical properties of aluminum coils: high-quality aluminum materials, plastics and adhesives are selected, and advanced composite technology is adopted. The product has the flexural and flexural strength required by the decorative board. Under the four-season climate, changes in wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion, etc.

5. Environmental protection of aluminum coils: aluminum coils are corrosion-resistant, strong in impact resistance, easy to maintain, and resistant to pollution. Material. These five characteristics are possessed by aluminum coil and its performance as a building material
