Import Billet, Steel Coil, Steel Bar, Roof — Buy in wholesale FOB from Supplier in China

Steel billet is a semi-finished long steel product, typically square or round in cross-section, produced by continuous casting or rolling from liquid steel. Qipu Building Materials Shanghai Co., Ltd supplies carbon steel billet with nominal composition of carbon 0.15-0.25%, manganese 0.40-0.70%, with iron as balance, suitable for subsequent hot rolling into bars, rods, or structural sections. Billet dimensions are typically 100 mm x 100 mm to 200 mm x 200 mm in square section, with lengths of 6 metres to 12 metres standard for global trade. The as-cast surface condition, corner radius, and straightness tolerance determine suitability for direct rolling or require conditioning by grinding or scarfing.

Material grades supplied include plain carbon structural steels corresponding to Q235, Q275, or comparable ASTM A36, S275JR, and JIS SS400 specifications, depending on end-use requirements and destination market standards. Deoxidation practice may be rimmed, semi-killed, or killed, affecting internal soundness and suitability for cold drawing or surface-critical applications. Typical sulphur and phosphorus limits are 0.040% maximum each for general structural grades, with lower limits available for special quality agreements. The billets may be supplied as-cast, or conditioned by abrasive grinding to remove surface defects prior to shipment, depending on customer specification and rolling mill requirements.

Primary applications include re-rolling into concrete reinforcing bars, merchant bars, wire rod, and small structural sections for construction and infrastructure. Secondary uses encompass forging stock for automotive and machinery components where subsequent hot working refines cast structure. Buyers typically include steel re-rolling mills in South Asia, Southeast Asia, Africa, and the Middle East, as well as trading houses managing arbitrage between Chinese export availability and regional demand. When sourcing, confirm size tolerance per GB/T 702 or equivalent, permissible surface defect depth, and whether corner cracks or longitudinal cracks are within acceptable limits for your rolling mill feedstock criteria.

Qipu Building Materials Shanghai Co., Ltd is located at 888 Huanhu West Second Road, Shanghai Lingang Pilot Free Trade Zone, Shanghai 200120, China. The company operates under the harbor trust tier. The response rate is recorded at 0.00% with zero average response hours, suggesting that automated or manual communication channels are not currently yielding measurable engagement. No established date, registered capital, employee count, or annual revenue figures appear in the available profile, so these must not be stated as fact.

The supplier's product range spans steel and construction materials including cold rolled steel coil, hot rolled flat steel, billet, railroad track steel rail, carbon steel, stainless steel, special steel, rigid bar, wire rod, galvanized steel, angle steel, construction steel, steel plate, roofing materials, and non-ferrous metals. This broad portfolio suggests trading or diversified distribution rather than sole manufacture of billet. The Shanghai Lingang location provides proximity to Yangshan deep-water port, advantageous for export logistics. Buyers should verify whether billet is sourced from affiliated mills or third-party producers, and request mill test certificates with full chemical and mechanical data traceable to the original melt shop.
