Precautions for purchasing aluminum profiles for construction

At present, the types of aluminum profiles produced in my country can be divided into: anodized colored profiles, electrophoretic painted profiles, powder sprayed profiles, fluorocarbon paint sprayed profiles, and heat insulating profiles. The level and type of aluminum profiles are comparable to those abroad. Among them, architectural aluminum products have the advantages of high strength, light weight, corrosion resistance, good decoration, long service life and rich colors. The surface of a good product will not lose its gloss and color within 20 years. The editor tells you some precautions for purchasing aluminum profiles for construction: 　　 1. Check the product factory certificate, pay attention to the factory date, specifications, technical conditions, company name and production license number.　　2. Observe the surface condition of the product carefully. The product should be bright in color and good in luster, and the surface should not have obvious scratches, bubbles and other defects.　　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 1.2mm. 4. Pay attention to the thickness of the surface coating of the aluminum profile product. The film thickness of the anodized product is not less than 10μm, the film thickness of the electrophoretic coating product is not less than 17μm, and the thickness of the powder spray coating does not exceed the range of 40-120μm. Fluorocarbon The paint spray product should be above the second coating and not less than 30μm.　　5. Users in coastal areas choose electrophoretic painted aluminum profiles, powder sprayed profiles or fluorocarbon sprayed profiles with better corrosion resistance.　　6. u200bu200bBrushes 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 when cleaning aluminum profiles, but other organic substances cannot be used.
