Aluminum alloy profile products have become an important family decoration because of their high strength, light weight, corrosion resistance, good decoration, long service life and rich color. At present, the types of aluminum alloy building materials sold on the market are mainly divided into anodic oxidation coloring section, electrophoresis coating section, powder coating section, fluorocarbon coating section, heat insulation section bar. Consumers in the purchase and use of aluminum alloy profiles, should pay attention to the following six points:
Aluminum alloy building profile
1. ask the seller for the quality report of the product.
2. check the product ex factory certificate, pay attention to the date of production, specifications, technical conditions, enterprise name and production license number.
3. look carefully at the surface condition of the product, the product should be bright color, good gloss, the surface can not have obvious scratches, bubbles and other defects.
4. we must pay attention to the product wall thickness, doors and windows material thickness should be no less than 1.2mm.
5. pay attention to the product surface coating thickness, oxidation products of the anodic film thickness not less than 10 m, the electrophoresis paint product film thickness not less than 17 mu m, the thickness of the coating powder coating does not exceed the 40-120 m range, fluorocarbon paint spraying products should be coated in two above, not less than 30 m.
6. users of coastal areas should have better corrosion resistance electrophoretic coating profiles, powder coating profiles or fluorocarbon spray profiles.
