Import A36 120mm Carbon Steel Sheet — Buy in wholesale FOB from Supplier in China

Jiangsu Steel Group Co., Ltd. supplies A36 carbon steel sheet at 120mm thickness, a hot-rolled structural steel grade conforming to ASTM A36/A36M. The A36 designation specifies minimum yield strength of 250 MPa and tensile strength of 400 to 550 MPa, with carbon content typically 0.26% maximum, manganese 0.80 to 1.20%, and phosphorus and sulfur limited to 0.04% each. At 120mm thickness, this material falls within the heavy plate category where through-thickness properties and ultrasonic testing become relevant for structural applications. The supplier lists standard dimensional ranges: thickness 8mm to 600mm, width 1500mm to 4200mm, and length 6000mm to 18000mm, with this 120mm sheet representing a mid-range heavy plate product.

The A36 grade is produced to multiple national standards including ASTM A36 (USA), JIS SS400 (Japan), and GB Q235 (China), with partial equivalency across specifications though carbon equivalent values and impact requirements may differ. For 120mm plate, typical carbon equivalent (CE) ranges from 0.35 to 0.45 depending on deoxidation practice and microalloying, affecting weldability and preheat requirements. The supplier offers surface preparation by customer requirement, including shot blasting to SA 2.5 and shop primer application, or supply in as-rolled condition with mill scale intact. Heat treatment options are not specified but normalized or quenched and tempered delivery may be available for enhanced through-thickness properties.

Primary applications include load-bearing columns, bridge girders, heavy machinery bases, pressure vessel shells, and offshore platform components where the 120mm thickness provides section modulus for bending resistance. Buyers encompass structural steel fabricators, shipyards, boiler manufacturers, and infrastructure contractors. The material is suitable for welding with appropriate preheat based on hydrogen input and restraint level, though buyers should confirm that the supplier's A36 meets the specific standard revision required for their project, as A36/A36M-19 introduced changes to tensile testing procedures. Trade terms offered include FOB, CFR, and CIF with payment by T/T or L/C at sight.

Jiangsu Steel Group Co., Ltd. is headquartered at 10/F, No. 257 Siping Road, Hongkou District, Shanghai 200080, with steel production or trading operations linked to Jiangsu Province. The supplier holds an imported tier and harbor trust tier, indicating some level of platform verification. The response rate and average response hours show zero activity, suggesting buyers may encounter delays in initial communication and should prepare to follow up persistently or engage through alternative contact methods.

The company profile does not disclose founding date, mill ownership (whether integrated producer or trader), annual output, workforce size, or specific mill equipment. No quality management certifications are listed in the source data. The breadth of grades offered, from A36 through A573GR.70, Q275, and SM400 series, suggests either substantial inventory or mill partnership arrangements across multiple product lines. Buyers should verify whether Jiangsu Steel Group operates its own rolling mill or sources through trade relationships, as this affects lead time consistency, material traceability, and the ability to accommodate custom requirements.
