Aluminium profile owns many advantages, such as light weight, good workability, high mechanical strength, etc. So, it has been widely used in buildings for many years in doors, windows, curtain wall and other products. Aluminum is a kind of light metal with silver luster. Its high corrosion resistance has the following two features:

 

The higher purity it is, the better corrosion resistance it will be. First of all, there is a layer of thin and fine natural oxide film on the aluminium surface because pure aluminum reacts with oxygen in the air. The speed of generating the oxide film is faster and thicker than other metals. Then, it prevents the further corrosion of harmful gas in the air and water.

 

Aluminum profile has high mechanical strength but low corrosion resistance. Although the pure aluminum profile has good corrosion resistance, the mechanical strength is poor. To some extent, it must restrict the use of aluminum. For this reason, it is necessary to put appropriate magnesium copper, zinc and other metals in aluminum in order to make into various types of aluminum alloy. It can improve the mechanical strength of aluminium, expand the use scope greatly. However, its corrosion resistance is poorer than that of pure aluminum, so it is easy to corrode because of oxidation. The powder coating on aluminum alloy profile can maintain it.

 

Powder coating aluminum profile has not only high corrosion resistance, but also diversified color and good appearance quality and many other advantages. The rich color is coordinated with a variety of exterior buildings’paints, which can be used to different styles of buildings.
