Import Baosteel Hdg Coils — Buy in wholesale FOB from Supplier in China

Challenge International Industry Group Ltd. supplies Baosteel hot-dipped galvanized steel coils with zinc coating from 80 to 500 gsm, thickness from 0.2 to 1.6 mm, and widths of 750 to 1250 mm. The coils weigh 2 to 10 tons each, with a 508 mm inner diameter, and conform to GB2518-88 and JIS G3302-98 standards. Grades available include SGCC, S, CS, and JG, sourced directly from Baosteel, one of China's established integrated steel producers. These specifications are drawn from the supplier's own listing data, which positions the material for construction, automotive, appliance, and roofing applications.

The zinc coating weight range of 80-500 gsm corresponds to coating designations from Z08 to Z500 in Chinese standard terminology, with heavier coatings providing extended corrosion protection in aggressive environments. Typical substrate steel for this product category is low-carbon cold-rolled strip, with commercial quality (CQ) or drawing quality (DQ) depending on the grade suffix. The JIS G3302-98 standard specifies coating adhesion tests via 180-degree bending, and surface finishes range from regular spangle to minimized spangle or zero spangle for painted applications. Buyers should note that the supplier's data does not indicate which surface finish or spangle type is offered, so this should be confirmed directly.

The primary buyers for these coils are construction material distributors, roofing and cladding fabricators, automotive stampers, and white-goods manufacturers who require corrosion-resistant sheet steel in coil form. Trade terms mentioned include CIF and FOB, though exact ports, lead times, and minimum order quantities are not stated in the source data and must be confirmed with Challenge International Industry Group Ltd. Mill test certificates are referenced for customs clearance, which buyers should request to verify chemical composition, mechanical properties, and coating weight per coil. Given the supplier's harbor trust tier and zero percent response rate, prospective buyers should initiate contact well in advance and consider requesting current mill production certificates before placing orders.

Challenge International Industry Group Ltd. is located at No 105 Gaoyi Road, Shanghai 200439, China, operating as an imported-tier supplier with harbor trust tier classification. The company's response rate is listed at 0.00 percent with zero average response hours recorded, which indicates no recent engagement data is available through the platform. The supplier's profile does not state year of establishment, number of employees, annual revenue, factory ownership, or specific export markets served. What the listing does establish is that the company positions itself as a conduit to Baosteel-produced material, offering standard Chinese mill-origin galvanized steel coils for international trade.

The supplier's profile provides no information about verification audits, third-party certifications held, past transaction history, or customer references. There is no mention of warehousing capacity, processing capabilities such as slitting or cut-to-length, or logistics arrangements beyond the reference to CIF and FOB terms. Buyers should treat the supplier's claims as unverified pending direct due diligence, and should request company registration documents, Baosteel mill authorization if claimed, and recent bill of lading references to establish trading track record. The absence of response data suggests either a new listing or inactive account management, so initial contact should include specific technical enquiries to gauge product knowledge and responsiveness.
