Flatness of
aluminum coil: There is no compound 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 cutting. The decorativeness of aluminum coil: Because of its good corrosion resistance, sufficient strength, excellent process performance and welding performance, special aluminum plates for architectural decoration are widely used in building frames, doors and windows, ceilings, decorative surfaces, etc. Such as various architectural doors and windows, aluminum profiles for curtain walls, aluminum curtain wall panels, profiled panels, checkered panels, color coated aluminum panels, etc. Weather resistance of aluminum coil: The surface of aluminum and its alloys is easy to form a dense and strong Al2O3 protective film. This protective film can only be destroyed by the intense action of halogen ions or alkali ions. Therefore, aluminum has good resistance to atmospheric (including industrial atmosphere and ocean vapor) corrosion and water corrosion. It can resist the corrosion of most acids and organics, adopts corrosion inhibitors, can resist weak alkali corrosion; adopts protective measures to improve the corrosion resistance of aluminum alloy
Mechanical properties of
aluminum coils: use high-quality aluminum, plastics and adhesives, and use advanced composite technology. The product has the required flexural and flexural strength for decorative panels. In the four-season climate, changes in wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion, etc. Environmental protection of aluminum coil: aluminum coil is corrosion-resistant, strong impact resistance, easy to maintain, resistant to pollution, does not corrode itself to produce toxins, and does not cause any harmful gases, and has strong fire resistance. It is a safe fireproof material. These five characteristics are owned by aluminum coils, and they are also the performance that it has as a building material!
If there are too many impurities inthe
aluminum coil, there will be defects in quality after it is made into other products. When the aluminum coil is processed, the oxide layer on the surface of the aluminum coil will be destroyed again, so that the gain is not worth the loss. The aluminum coil is very decorative. When buying, we should not only pay attention to its performance, but also carefully check its appearance. The surface of qualified aluminum coils must not have obvious indentation, missing coating, ripples, scratches, and drums. Bubbles are not allowed. These are easy to see, mainly due to the chromatic aberration of the aluminum coil, if you are not careful, it will affect the decorative effect.
