Import Color Coated Steel Coils — Buy in Bulk from Supplier in China

The color coated steel coils from Changzhou Changke are manufactured with a pre-painted galvanized or galvalume substrate, featuring a lacquer-based topcoat applied via continuous coil coating lines. The thickness range is 0.2mm to 0.80mm, with widths between 1,000mm and 1,250mm, suitable for roll-forming into roofing, siding, and appliance panels. The lacquer finish provides enhanced color retention and mechanical durability compared to basic acrylic coatings.

The substrate is typically hot-dip galvanized steel with zinc coating weights of 80 to 150 g/m², or an aluminum-zinc alloy (Galvalume) for higher corrosion resistance. The coating system includes a primer, topcoat, and sometimes a backcoat for structural stability. The product is designed for applications requiring consistent color across large surface areas, such as commercial buildings and HVAC ductwork. Typical bending radii are 2.5 times the thickness to avoid coating cracking.

This product is used by manufacturers of prefabricated buildings, automotive body components, and household appliances in Southeast Asia and the Middle East. Buyers typically order in full coils or cut-to-length segments. Packaging is in wooden pallets with anti-rust paper and plastic wrap. Trade terms are commonly FOB or CIF, with lead times varying by order volume. Minimum order quantities are not stated and must be confirmed with the supplier.
