Aluminum railings do not rust, making them an excellent choice for outdoor use. Unlike iron and steel, aluminum naturally forms a protective oxide layer when exposed to air, which acts as a barrier against corrosion.
However, in harsh environments—particularly coastal areas with salt spray—aluminum can still experience pitting or galvanic corrosion if it comes into direct contact with certain other metals.
To enhance durability, most aluminum railings are treated with powder coating or anodizing, which provide an extra shield against moisture and pollutants.
With proper installation and occasional cleaning with mild soap and water, powder-coated aluminum railings can maintain their appearance and structural integrity for decades, even in demanding outdoor conditions.
