The selection of the trolley line is the reason for the aluminum profile

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

Aluminum profiles have high mechanical strength but low corrosion resistance. Although the corrosion resistance of pure aluminum is good, it has poor mechanical strength and is easily deformed. This restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc, and other metals to the aluminum, and slide the wire. Made of various types of aluminum alloys, the mechanical strength of aluminum is greatly improved, and the application range is greatly expanded, but the corrosion resistance is worse than that of pure aluminum, and thus it may be corroded by oxidation. This requires a painting process to protect the aluminum profiles.

In addition to the high corrosion resistance of the aluminum processed through the painting process, it also has a variety of colors, which can make the layout more harmonious.
