Are aluminum sheets affected by weathering?

Aluminum sheets are generally resistant to weathering, thanks to a protective oxide layer that forms on the surface when exposed to air. This layer prevents further oxidation and corrosion, making aluminum durable even in harsh weather conditions. However, the rate of weathering can be influenced by factors such as pollution, temperature fluctuations, and the presence of aggressive chemicals. While aluminum maintains its structural integrity well, it may experience some surface changes like patina formation over time, but these are mostly cosmetic and do not compromise the material's performance significantly.
