What are the precautions when purchasing aluminum profile shells?

Aluminum profiles are made by extruding aluminum rods through different degrees of hot melting to form different shapes of aluminum materials. Aluminum profiles are also widely used and are often used in construction, home improvement, and industry. Among the many varieties of aluminum processed materials, a large number of international advanced products and national famous brand products have emerged, representing the mainstream direction of the development and application of modern aluminum processing technology in my country. So what are the precautions when purchasing aluminum profile shells? The following Zhongyilong editor will introduce to you.

　　What are the precautions when purchasing aluminum profile shells:

　　 1. Check the product delivery certificate, pay attention to the delivery date, specifications, technical conditions, company name and production license number.

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 spraying The product should be above the second coating, not less than 30μm.

　　 5. The users in coastal areas should choose electrophoretic coating profiles, powder coating profiles or fluorocarbon coating profiles products with better corrosion resistance.

　　 6. Do not use brushes or other hard objects as cleaning tools during daily maintenance. Choose soft cotton yarn and cotton cloth.

　　 7. Water, detergent and soap can be used for cleaning, but other organic substances cannot be used.

The above is an introduction to the precautions for the aluminum profile shell when purchasing. The aluminum alloy profile is a commonly used profile in daily life. It has high strength, light weight, corrosion resistance, good decoration, and long service life. The rich color and other characteristics can bring us great convenience in use. Generally speaking, the surface of a good profile product can ensure that it will not lose light or change color within 20 years.
