Import A36 70mm Carbon Steel Sheet — Buy in wholesale FOB from Supplier in China

A36 70mm carbon steel sheet from Jiangsu Steel Group Co., Ltd. is a heavy-gauge structural steel plate supplied under ASTM A36 / A36M, with a nominal thickness of 70 mm falling within the source range of 8 mm to 600 mm. The sheet is available in widths from 1500 mm to 4200 mm and lengths from 6000 mm to 18000 mm, with surface finish options including clean, blasting, or painting to customer specification. This grade is a low-carbon structural steel with typical yield strength of 250 MPa and tensile strength in the 400 MPa to 550 MPa range, making it suitable for load-bearing applications where ductility and weldability are required alongside moderate strength.

The material conforms to multiple international standards: AISI, ASTM, BS, DIN, GB, and JIS. Jiangsu Steel Group lists equivalent and related grades including A283GR.C/GR.D, A573GR.58/65/70, SS400, SM400A/B/C, S235JR/J0/J2, S275JR/J0/J2, S275N/NL, S275M/ML, and Q235/Q275 series, reflecting the broad cross-referencing common in Chinese mill production. Typical carbon content for A36 is 0.25% to 0.29% by weight, with manganese at 0.80% to 1.20% and phosphorus/sulfur each limited to 0.040% under ASTM specification. The 70 mm thickness positions this sheet in heavy-plate territory, where through-thickness properties and ultrasonic testing become relevant considerations.

Primary applications span building construction, bridges, architecture, vehicle components, shipping structures, high-pressure containers, boilers, and large structural steelwork. Buyers typically include structural steel fabricators, shipyards, pressure vessel manufacturers, and heavy engineering contractors. Trade terms offered are FOB, CFR, and CIF; payment terms include T/T and L/C at sight. The supplier's Shanghai office address is 10/f No.257 Siping Road, Hongkou, Shanghai 200080, though buyers should confirm mill location and dispatch port for 70 mm plate logistics, as heavy-gauge material often ships from northern or eastern Chinese ports rather than Shanghai directly.

Jiangsu Steel Group Co., Ltd. maintains a registered office at 10/f No.257 Siping Road, Hongkou, Shanghai 200080, China. The supplier profile indicates an imported tier and harbor trust tier, with response metrics showing 0.00% response rate and zero average response hours. These signals suggest limited or unmonitored enquiry responsiveness through the platform, and buyers should treat direct communication as essential rather than relying on platform-mediated messaging.

The listing presents Jiangsu Steel Group as a multi-standard steel supplier offering carbon steel coils and sheets across ASTM, GB, JIS, and European equivalent grades. No verified factory location, production capacity, workforce size, revenue figures, or client references are disclosed in the source data. Buyers should conduct independent due diligence on mill credentials, ISO 9001 quality management certification, and environmental compliance status before committing to heavy-plate orders.
