The level and type of domestically produced aluminum alloy profiles have been comparable to foreign products. Aluminum alloy profiles can be divided into: electrophoretic paint profiles, anodized color profiles, fluorocarbon paint spray profiles, powder spray profiles, heat insulation profiles.
Aluminum alloy profiles have the characteristics of light weight, high strength, good decoration, corrosion resistance, long life, and rich colors. The product surface of high-quality profiles does not lose light without discoloration for 20 years.
Please pay attention to the following points when purchasing aluminum alloy profiles:
First, the wall thickness of the profile: The thickness of the door and window material should not be less than 1.2 mm. The wall thickness must be calculated according to the area bearing capacity.
Second, the thickness of the product surface coating: the film thickness of the electrophoretic coating product is not less than 17μm, the film thickness of the anodized product is not less than 10μm, the thickness of the powder coating does not exceed the range of 40-120μm, and the fluorocarbon coating is sprayed The product should be more than two coats, not less than 30μm.
Third, the surface of the product should have bright colors and good gloss, and the surface can not have obvious defects such as air bubbles and scratches.
Fourth, daily use can not be used as a cleaning tool such as a brush, should choose a soft cotton gauze.
Fifth, in the coastal areas, it is best to choose powder sprayed profiles, electrophoretic painted profiles or fluorocarbon sprayed profile products with good corrosion resistance.
Sixth, water, soap and soap can be used to clean the profiles, but no other organic materials can be used.
Seventh, check product certifications, company names, specifications, date of manufacture, technical conditions, and production licenses.
