Aluminum is a relatively lively light metal with a silvery white luster erosion with the following two characteristics:
The higher the purity of the aluminum profile for doors and windows
, the better the corrosion resistance, mainly because the pure aluminum reacts with the oxygen in the air to produce a thin and dense natural oxide film on the aluminum surface, which is much faster than other metal oxide films. much thicker.
The mechanical strength of aluminum doors and windows is high, and although pure aluminum has good corrosion resistance, it restricts the application of aluminum to a certain extent. Prevent the further corrosion of aluminum doors and windows by harmful gases and moisture in the air, and play a protective role.
Therefore, people add an appropriate amount of magnesium, copper, and other metals, such as zinc, to make various types of aluminum alloys, which improve the mechanical strength of door and window aluminum and expand its application range, but its corrosion resistance is worse than pure aluminum. Therefore, it may be oxidized and corroded. This requires the input of a powder coating that protects the aluminum alloy profiles.
Powder coating can make aluminum doors and windows not only have high corrosion resistance, but also have many characteristics such as various colors and good surface texture.
The strong properties of aluminum windows and doors can prevent it from rotting, rusting or bending. Low-density metal is durable in UV light and all weather conditions, with no expansion or shrinkage issues.
When decorating a house, color and style often become the main factors. However, limited options are not a cause for concern for aluminum. There are hundreds of aluminum colors and finishes on the market. Plus, if you want to try out the design, you can even choose a different color for the inside and outside of the aluminum doors and windows!
