从China供应商批发进口A36 55mm Carbon Steel Sheet — FOB条款

This A36 55mm carbon steel sheet from Jiangsu Steel Group Co., Ltd. is a heavy-plate structural grade conforming to ASTM A36 Mines standard, with a nominal thickness of 55mm that sits well within the supplier's stated rolling range of 8mm to 600mm. The sheet is offered in widths from 1500mm to 4200mm and lengths from 6000mm to 18000mm, making it suitable for large-scale fabrication where substantial load-bearing capacity is required. Grade equivalency includes A283GR.C/GR.D, A573GR.58/65/70, SS400, SM400A/B/C, S235JR/J0/J2, S275JR/J0/J2, S275N/NL/M/ML, 250/L0/L15, and Q235/Q275 series, allowing cross-referencing with European, Japanese and Chinese national standards. The surface condition is supplied clean, with optional blasting and painting to customer specification.

At 55mm thickness, this plate falls into the heavy-gauge category where through-thickness properties become critical for welded structures. Typical carbon content for A36 plate in this thickness range runs 0.25-0.29% with manganese at 0.80-1.20%, though the exact ladle analysis should be requested on the mill test certificate. Yield strength for A36 at this thickness typically remains at or above 250 MPa, with tensile strength of 400-550 MPa and minimum elongation of 20% in 200mm gauge length. The supplier notes applications including building construction, bridges, architecture, vehicle components, shipping, high-pressure containers, boilers and large structural steel, which aligns with the heavy-plate end-use profile. Standard industry practice for plates of this thickness involves normalised rolling or thermo-mechanical controlled processing to assure through-thickness toughness, though buyers should confirm which process route applies to their specific order.

Primary buyers include steel fabricators, shipyards, pressure vessel manufacturers and heavy civil engineering contractors who require thick plate for welded assemblies. The 55mm gauge is particularly relevant for bridge girders, offshore transition pieces, crane booms and thick-walled pressure vessels where section modulus and fatigue resistance govern design. Trade terms offered are FOB, CFR and CIF, with payment by T/T or L/C at sight. Buyers should confirm whether cutting to size, edge preparation or ultrasonic testing are available as added services, and should verify the specific dimensional tolerance class (typically EN 10029 Class A or ASTM A6/A6M) that applies to their order.

Jiangsu Steel Group Co., Ltd. maintains a registered address at 10/F, No. 257 Siping Road, Shanghai 200080, Hongkou District, China, placing its commercial operations in one of the country's principal steel trading and logistics hubs. The supplier is classified as an imported-tier vendor with a harbor trust designation, which indicates the profile has been brought into the marketplace dataset rather than created natively. The response rate is recorded at 0.00% with an average response time of zero hours, suggesting either a new listing, a dormant account, or data that has not yet populated with engagement metrics. Buyers should treat direct communication as unverified until a response is received.

The listing presents a broad grade portfolio spanning ASTM, JIS, EN and GB standards, which implies either substantial rolling mill capacity or trading relationships with multiple mills. No manufacturing facility details, ISO certifications, annual tonnage, or specific quality system accreditations are stated in the source material. The company does not claim any particular niche specialisation, presenting instead as a general carbon steel plate and coil supplier. Buyers are advised to request a current mill test certificate, ISO 9001 certificate if claimed, and details of the actual producing mill before committing to an order.
