Aluminum profiles have been widely used in building

Aluminum profiles have been widely used in building doors and windows, curtain walls and other products for many years because of their small specific gravity, easy processing, and high mechanical strength.  Aluminum is a relatively lively light metal with silver-white luster, and its corrosion resistance has the following two characteristics:

The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air to produce a thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films, which prevents further corrosion of harmful gases and moisture in the air and plays a protective role;

Aluminum profiles have high mechanical strength, but low corrosion resistance. The corrosion resistance of pure aluminum is good, but the mechanical strength is poor, which restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types of Aluminum alloy greatly improves the mechanical strength of aluminum and greatly expands its application range, but its corrosion resistance is worse than that of pure aluminum, so it may be corroded due to oxidation. This requires powder coating to protect the aluminum alloy profile.

In addition to high corrosion resistance, powder-coated aluminum profiles also have many advantages such as diversified colors and good surface texture, which echoes with various colors of architectural exterior wall coatings to adapt to different building styles.
