Coated aluminium coil is one of the most widely used processed aluminum materials in modern industry. Compared with plain aluminum coil, coated aluminium coil has a protective and decorative layer applied to the surface, which greatly improves corrosion resistance, weather resistance, durability, and appearance.

The lifespan of coated aluminium coil depends on several key factors, including the type of coating, coating thickness, alloy quality, and the environment in which the material is used. Different coatings provide different levels of protection, so the service life can vary significantly.
