Color coated steel sheet
Color coated steel sheet is made of galvanized sheet, aluminum-zinc sheet, and aluminum-zinc-magnesium as the substrate. After surface pre-treatment, color coated steel sheet is coated with multi-layer liquid paint by roller coating method, and then baked and cooled. Color coated steel sheet use coatings of various systems such as polyester, high-weather-resistant polyester, and polyvinylidene fluoride.
Color coated steel sheet have excellent durability, corrosion resistance and formability.
Color coated steel product are widely applied in home appliances, decoration, construction, automotive and other industries.
