Import A36 Black 8mm Carbon Steel Sheet — Buy in wholesale FOB from Supplier in China

This black 8 mm carbon steel sheet from Jiangsu Steel Group Co., Ltd. carries ASTM A36 certification and is offered in hot-rolled coil and plate form with thickness starting at 8 mm. The supplier's dimensional envelope runs 1500-4200 mm in width and 6000-18000 mm in length, with the black mill finish retained unless the buyer requests shot blasting or protective painting. The grade portfolio extends well beyond A36 to include A283, A573, SS400, SM400, S235, S275 and Q-series equivalents, giving engineers latitude to match national standards. Surface options of clean, blast-cleaned, or painted finish are available per customer specification.

At 8 mm thickness, A36 plate sits in the light structural range where hot rolling from continuously cast slab provides uniform through-thickness properties and acceptable flatness without the cost of further reduction. The typical microstructure is ferrite-pearlite with grain size ASTM 5-8, delivering the specified 250 MPa yield strength and 20% minimum elongation in 200 mm gauge length. For black finish orders, the adherent mill scale offers temporary atmospheric protection during shipping; where longer storage is anticipated, oiling or VCI wrapping should be negotiated. The supplier does not state normalising or quenching and tempering capability in the listing, so special heat treatment must be confirmed directly.

Target markets include bridge builders, shipyards, pressure vessel fabricators, boiler manufacturers and general construction contractors who need certifiable structural plate with multi-standard compliance. The 8 mm thickness is widely used for tanks, ducting, web plates in welded girders, and shell courses in moderate-pressure vessels. Trade terms are FOB, CFR or CIF, with payment by T/T or letter of credit at sight. Given the zero recorded response rate, buyers should treat initial enquiries as exploratory, use detailed technical RFQs to gauge competence, and consider an independent factory audit or pre-shipment inspection before committing to volume orders.

Jiangsu Steel Group Co., Ltd. maintains its registered office at 10/f No.257 Siping Road, Shanghai 200080, in Hongkou District, positioning its commercial function in one of China's principal steel trading hubs. The supplier profile carries an imported tier designation and harbour trust level, with a response rate of 0.00% and no recorded average response hours. This pattern suggests either a new listing, a dormant account, or a trading desk that fields enquiries through off-platform channels. Buyers should not assume unresponsiveness equates to non-existence, but should verify active operations through direct phone, email, and reference checks before depositing funds.

No information is provided on mill location, production equipment, annual tonnage, workforce, quality certifications, or client references. The listing's strength is the breadth of grades and dimensional range offered, implying either mill-direct capability or strong trader relationships with multiple rolling mills. Prospective buyers should ask for the company's business licence, VAT number, and any ISO 9001, ISO 14001, or API Q1 certificates. They should also clarify whether Jiangsu Steel Group Co., Ltd. is a manufacturer, a commission agent, or an independent trader, as this affects warranty recourse and technical accountability.
