Aluminum will naturally form a dense aluminum oxide film in the air, which can effectively prevent aluminum from further reacting with oxygen, moisture and other corrosive substances in the external environment. This natural protection mechanism provides basic corrosion resistance for aluminum curtain walls. Compared with some metal materials that are prone to rust, aluminum curtain walls can maintain their appearance and performance stability for a long time under general environmental conditions.

In addition to the protection of natural oxide film, modern aluminum curtain walls also use a variety of advanced surface treatment technologies to further improve their corrosion resistance. For example, anodizing treatment uses electrochemical methods to generate a thicker and denser oxide film on the aluminum surface, which enhances the resistance to corrosive media. Technologies such as powder coating and fluorocarbon paint spraying form a firm organic coating on the aluminum surface, which not only prevents corrosion, but also gives the Aluminum Curtain Wall a rich color. In coastal areas or areas with severe industrial pollution, these surface-treated aluminum curtain walls can withstand the erosion of salt spray, acid rain and chemical pollutants, and maintain good appearance and performance for a long time. For example, the aluminum curtain walls of seaside resort hotels or commercial buildings in coastal cities can remain bright and shiny and show excellent corrosion resistance even after long-term exposure to high salinity and high humidity environments.
