Building Material Aluminium Extrusion Profiles The building material Aluminium Extrusion Profiles products are made of aluminum and aluminum alloy materials, which have the advantages of high strength, light weight, corrosion resistance, good decoration, long service life and rich colors. Generally, a good product has no surface loss and no discoloration for 20 years. The product types can be divided into: anodized colored profiles, electrophoretic painted profiles, powder coated profiles, fluorocarbon paint spray profiles, and thermal insulation profiles. The surface of the product is bright and shiny, and the surface cannot have obvious scratches, bubbles and other defects. The thickness of the product door and window material should not be less than 1.0mm. The thickness of the surface coating: The film thickness of the anodized product is not less than 10 �¼m, the film thickness of the electrophoretic paint product is not less than 17 m, the thickness of the powder coating is not more than 40-120 1/4m, and the fluorocarbon paint product should be in the second Above the coating, it should not be lower than 30 1/4m.
