Aluzinc Coils are steel coils coated with a protective layer of an alloy that is 55% aluminum, 43.4% zinc, and 1.6% silicon. This coating provides superior, long-term corrosion resistance compared to galvanized steel, while maintaining the strength and formability of the steel. They are used in a wide range of applications, including construction (roofing, cladding), and are often available in pre-painted versions with various colors and finishes for aesthetic purposes.
Coating composition
A hot-dip process applies a coating of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon to the steel.
Pre-Painted Aluzinc Coils are steel coils coated with an aluminum-zinc alloy and then painted to improve corrosion resistance and aesthetics. This combination provides long-lasting protection against the elements, is durable, lightweight, and strong, making it ideal for construction, particularly roofing and cladding, as well as household appliances and other industrial uses. The paint can be applied in a wide range of colors and finishes.
