从China供应商批发进口6mm Carbon Steel Sheet — FOB条款

This 6mm carbon steel sheet is available in grades spanning A283GR.C/GR.D, ASTM A36, A573 series (GR.58, GR.65, GR.70), SS400, SM400A/B/C, S235JR/J0/J2, S275JR/J0/J2, S275N/NL, S275M/ML, 250/250L0/250L15, and Q235/Q275 series A/B/C/D. The 6mm thickness sits within the supplier's stated 8mm-600mm range, suggesting this specification may be sourced from coil slitting or special rolling programmes, as 6mm falls below the nominal lower bound. Standard mill width is 1500-4200mm with lengths of 6000-18000mm, though buyers should confirm 6mm availability in their required width and length combination. Surface condition is clean, with blasting and painting available as customer-specified secondary processing.

The grade selection covers structural carbon steels with yield strengths from 235 N/mm² (S235JR, Q235) through 275 N/mm² (S275, Q275) to 250 MPa minimum (Australian 250 grade), with tensile strengths typically 400-550 N/mm² depending on grade and thickness. ASTM A36, the most commonly specified grade in this list, has minimum yield strength of 250 MPa and tensile strength of 400-550 MPa for plates 6mm and under, with elongation of 20 percent in 200mm gauge length. The A573 grades offer improved toughness for pressure vessel and structural applications, while the S275 and Q275 series provide higher strength for reduced-weight designs in building construction and bridge engineering.

Primary applications include building construction, bridge fabrication, architectural metalwork, vehicle components, shipping hull and deck structures, high-pressure containers, boilers, and large steel frameworks. The 6mm thickness is particularly suited to secondary structural members, stiffeners, tank shells, and formed sections where moderate strength and good weldability are required. Buyers should specify the exact grade, test regime (impact testing temperature for JR, J0, J2, N, NL, M, ML suffixes), and any third-party inspection requirement (LR, ABS, DNV, or TUV). The supplier lists FOB, CFR, and CIF trade terms with T/T or L/C at sight payment, though specific pricing and minimum order quantities are not disclosed in the source data.

Jiangsu Steel Group Co., Ltd. maintains its registered office at 10/F, No.257 Siping Road, Hongkou District, Shanghai 200080, China, though the company name suggests Jiangsu Province as its operational or historical base. The supplier holds 'imported' tier status with 'harbor' trust tier classification. Its response rate shows 0.00 percent with zero average response hours, which may indicate a newly listed account, dormant profile, or measurement anomaly rather than operational scale. No manufacturing facility address, employee count, revenue, or founding year appears in the source data.

The company trades across a broad carbon steel portfolio from structural grades to pressure vessel specifications, implying either mill-direct supply, trading house relationships, or stockholding operations. The Shanghai office address places the commercial function within China's primary steel trading and finance hub, common for steel traders and large mills with separate commercial and production locations. Buyers should verify whether Jiangsu Steel Group Co., Ltd. operates its own rolling mill or sources through mill partnerships, and whether the 6mm specification represents regular stock or mill-direct order. Request mill test certificates with chemical composition and mechanical test results for the specific heat number, and confirm the certificate issuer matches the producing mill rather than a trading intermediary.
