What should be paid attention to when choosing aluminum profiles? The following is a brief introduction:
1. Check the product factory certificate, pay attention to the date of production, specifications, technical conditions, enterprise name and production license number.
2. Carefully observe the surface condition of the product. The product should have bright color and good luster. There should be no obvious scratch, bubble and other defects on the surface.
3. Pay attention to the wall thickness of the products. The thickness of the door and window materials should not be less than 1.2mm.
4. Pay attention to the thickness of the product surface coating. The film thickness of anodic oxidation product is not less than 10 μ m, the film thickness of electrophoretic coating product is not less than 17 μ m, the coating thickness of powder spraying is not more than 40-120 μ m, and the coating thickness of fluorocarbon paint spraying product should be more than the second coating, not less than 30 μ M.
5. The users in coastal areas should choose electrophoretic coating profiles, powder spraying profiles or fluorocarbon spraying profiles with good corrosion resistance.
6. During routine maintenance, brush and other hard objects should not be used as cleaning tools. Soft cotton yarn and cotton cloth should be selected.
