Aluminium naturally forms a protective oxide layer when exposed to air, preventing rust and severe corrosion. However, prolonged outdoor exposure can cause superficial oxidation or discoloration, especially in harsh environments (e.g., coastal or industrial areas). Modern architectural aluminium products, like those from Xtra Metal Group, integrate advanced treatments such as anodization or PVDF coatings to enhance weather resistance, UV stability, and color retention. Our engineered solutions ensure minimal maintenance and decades of aesthetic integrity, backed by 30+ years of global project expertise. For extreme conditions, we offer customized alloy compositions and protective finishes to match specific climate demands.
