Import Corrugated Steel Sheet — Buy in wholesale FOB from Supplier in China

The product offered by Qingdao Xinguangzheng Steel Structure Co., Ltd is a pre‑painted galvanized or galvalume corrugated steel sheet. It is supplied in nominal thicknesses ranging from 0.35 mm to 0.80 mm and widths of 600 mm to 1 050 mm, with lengths that can be cut to customer‑required sizes. The steel base conforms to grades SGCC, SGCH, Dx51D+Z and Q195, and the coating weight is specified between Z30 and Z275 for zinc and AZ30 to AZ150 for aluminium‑zinc. Paint thickness on the top side is typically 10 - 25 µm and 4 - 11 µm on the back side. Colour can be selected from RAL codes or a custom keyword. The annual production capacity is quoted as 28 000 Mt, and the supplier can pack the sheets in standard sea‑worthy bundles of 25 metric tons.

Pre‑painting combines a corrosion‑resistant zinc or aluminium‑zinc coating with a decorative finish, giving the sheet both durability and aesthetic appeal. The zinc coating (Z30‑Z275) provides a minimum protection comparable to a 100 g/m² zinc weight, while the galvalume option (AZ30‑AZ150) adds aluminium for enhanced longevity. The product complies with a range of international standards such as AISI, ASTM, BS, DIN, GB and JIS, which is typical for construction‑grade corrugated steel. Typical tensile strength for these grades lies around 250 MPa, and the material is suitable for cold‑rolled forming processes. In the market, such sheets are commonly used for industrial warehouses, large‑span roof structures and agricultural sheds.

Primary buyers include contractors, steel fabricators and importers supplying roofing or wall‑cladding projects in the Asia‑Pacific region. The supplier states a minimum order of 25 metric tons and a lead time of 15‑30 days after receipt of a T/T pre‑payment or L/C at sight. Trade terms can be negotiated as FOB, CIF, CFR, EX Works or FCA from Chinese ports, with payment typically by L/C at sight or T/T 30 % advance and the balance against a clean bill of lading. Packaging is performed in mill‑standard export bundles designed for sea freight handling. Prospective buyers should request a mill test certificate and coating verification before finalising the order.
