Aluminum profiles have been widely used in doors, windows and curtain walls of buildings for many years due to their small specific gravity, easy processing and high mechanical strength. Aluminum is a contrasting and vivid light metal with a silvery white luster. Its corrosion resistance has the following two characteristics:
The higher the purity, the better the corrosion resistance. The first reason is that pure aluminum has a synergistic effect on oxygen in the air. A thin layer of fine natural oxide film is produced on the aluminum surface, which is faster and thicker than other metal oxide films. This hinders the further corrosion of harmful gases and moisture in the air and provides a maintenance effect.
Aluminum profiles have high mechanical strength but low corrosion resistance. Although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, this restricts the use of aluminum to a certain extent. For this reason, everyone participates in appropriate metals such as magnesium, copper, zinc, etc. in aluminum to make various types. Aluminum alloy greatly improves the mechanical strength of aluminum and greatly expands the range of use, but its corrosion resistance is inferior to that of pure aluminum, so it can be corroded by oxidation. This requires powder coating to maintain the aluminum profile.
In addition to high corrosion resistance, the aluminum coated powder has many advantages such as diversified colors and good appearance. It is compatible with various exterior architectural paints to suit different building styles.
