What are the selection techniques for aluminum square-pass profiles?

Aluminum square pass is widely used as a decoration material in crowded public places such as airports, subways and stations, and its effect is very good. Then, aluminum square-pass profiles require know-how in the purchase and purchase of aluminum square-pass profiles. Let’s talk about the purchasing skills of aluminum square-pass profiles: 　　 Aluminum square-pass profiles purchase skills: 　　1. to make. At present, there are mainly the following types of aluminum materials on the market: According to the origin of aluminum materials, they are divided into ordinary aluminum, Guangzhou Aluminum and Southwest Aluminum; according to the international label of aluminum materials, they are divided into 1100, 3003 and 5005 labels; according to aluminum materials The strength of the alloy is divided into H24 and H18; according to the toughness of aluminum, it is divided into ordinary aluminum, aluminum-magnesium alloy and aluminum-manganese alloy. Most of the ceiling materials sold on the market now use ordinary aluminum, which is characterized by low strength, average flatness, strong toughness, and no deformation.　　2, surface treatment　　The surface treatment of aluminum square pass mainly includes the following types: spraying, baking, rolling and laminating. Among them, the service life of spraying and baking varnish is short, and color difference is easy to occur. The service life of roller coating is intermediate. The laminated board can be divided into ordinary film and imported film. The service life of imported film can basically reach 20 years without discoloration.　　3, craftsmanship 　　 The so-called craftsmanship is the bonding of the surface layer of the board, which is a piece that consumers have neglected. If the process is not good, it will have a great impact on the service life of the product. At present, the treatment processes of aluminum profile manufacturers on the market are very different. Many small factories basically adopt the workshop style and reduce the process life.　　 To sum up: the material, surface treatment and process are the three major factors that affect the profile square pass. As long as the above three points are done, you can correctly choose the top quality profile square pass product.
