Galvanized color-coated coils and galvanized color-coated coils are widely used because of their various colors and good performance, but many of them don’t understand the difference. Let’s introduce aluminizing for everyone. Zinc color coated coil and galvanized color coated coil.
Galvanized color-coated coil is a new type of material produced with the application of domestic high-end technology in recent years, often referred to as CCLI. It is made of aluminized zinc steel plate (containing 55% aluminum, 43% zinc and 1.6% silicon respectively) as the substrate, and then after surface degreasing, phosphating, and complex salt treatment, then a layer of organic paint Baked products. The corrosion resistance of galvanized steel sheet is better than that of galvanized steel sheet, generally: 5%NaCL 35℃, 1000Hrs, Good Field and Scribe No Blister 2mm or less. Therefore, the aluminum-zinc color-coated coil and the galvanized color-coated coil are essentially different in function.
In summary, aluminum-zinc color-coated coils have better corrosion resistance, corrosion resistance, and longer service life than galvanized color-coated coils. They are very suitable for construction and facility materials in harsh environments. The development prospects of aluminum-zinc color-coated coils in the current Chinese market are also relatively optimistic, and will gradually enter more fields and get better applications.
