Application description
Widely used for roofing and wall cladding in industrial buildings, warehouses, commercial complexes, agricultural sheds, and residential structures. Also suitable for canopies, awnings, fences, and portable cabins. The color coating provides both aesthetic appeal and long-term weather resistance, making it ideal for outdoor and decorative applications.
Production description
The process begins with hot-dip galvanized or galvalume steel coil. The coil is cleaned and chemically pretreated to enhance paint adhesion. A primer coat is applied, followed by a topcoat (polyester, PVDF, or HDP) using reverse roll coating. The coated strip passes through curing ovens to form a durable, uniform finish. After cooling, the pre-painted coil is fed into a roll forming line, where it is progressively shaped into the desired corrugated profile at room temperature. The formed sheet is then cut to specified length by a flying shear. Edge trimming or end-punching for fastening holes may be added. Finished sheets are inspected for color consistency, coating thickness, and profile accuracy before packing.
Shipping Packaging
For export, pre-painted corrugated sheets are interleaved with soft paper or foam to protect the color coating, stacked on ISPM-15 certified wooden pallets, secured with steel straps, and fitted with edge protectors. Wrapped with moisture-proof polyethylene. Labels include color code, grade, dimensions, and quantity for safe transport.
