It is a high-performance color coated composite metal coil formed by using hot-dip galvanized steel coils, hot-dip aluminum zinc coated steel coils, and electroplated galvanized steel coils as substrates, pre treating them with surface degreasing, phosphating, etc., coating them with one or more layers of organic coatings through continuous roll coating technology, and then curing them through high-temperature baking. It combines the mechanical strength of steel with the anti-corrosion, weather resistance, and decorative properties of organic coatings, making it a core material in fields such as construction, home appliances, and transportation.
