How to buy aluminum profiles?

The aluminum alloy building profiles produced in China are comparable to those in foreign countries in terms of level and variety.

Product categories can be divided into: anodized coloring profiles, electrophoretic coating profiles, powder spraying profiles,fluorocarbon paint spraying profiles, and heat insulation profiles.
Aluminum alloy building profile products have the advantages of high strength, light weight, corrosion resistance, good decoration, long service life and rich colors. Generally, the surface of a good product does not lose its gloss or change its color within 20 years.
Pay attention to the following points when purchasing and using aluminum extrusions profiles:
1. Check the product delivery certificate, pay attention to the delivery date, specifications, technical conditions, company name and production license number.

3. Be sure to pay attention to the wall thickness of the product. The product thickness of the door and window materials should not be less than 1.0mm.
4. Pay attention to the thickness of the product surface coating, the film thickness of the anodized product is not less than 10μm, the film thickness of the electrophoretic paint product is not less than 17μm, the thickness of the powder spray coating does not exceed the range of 40-120μm, fluorocarbon paint The product should be above the second coating, not less than 30μm.
5. Users in coastal areas are better to choose electrophoretic coating profiles, powder coating profiles or fluorocarbon coating profiles products with better corrosion resistance.
6. Brushes and other hard objects cannot be used as cleaning tools during routine maintenance. Soft cotton yarn and cotton cloth should be selected.
7. Water, detergent and soap can be used for cleaning, but no other organic substances can be used.
