Key features

S460M and Q460C hot rolled steel plates allow structural engineers to design taller buildings with reduced steel tonnage, saving foundation and construction costs.

Our hot rolled plates up to 3000mm width cover entire girder web depths without longitudinal splices, accelerating bridge fabrication and improving structural integrity.

S690QL hot rolled steel plate provides the ultra-high yield strength required for lightweight, long-reach crane booms while maintaining excellent low-temperature toughness.

AI-Powered supplier vetting

SummaryCNB NEW MATERIAL (TIANJIN) CO., LTD. is a China-based trading company established in 2023 with three employees. It reports quality assurance, raw-material traceability, written inspection instructions, in-stock capability, and customization from samples or designs. The company states that 90% of sales are exports and cites international companies as fixed raw-material customers, although no specific case details are provided. Service reach is limited: it reports no overseas agents or branches, overseas warehouses, overseas showroom, offline trade-show participation, or overseas service countries. R&D evidence is weak, with no new product information in the past year, no ODM, no SDK, and no branded OEM capability. Financial information provided shows zero operating revenue and zero profit-related figures for the stated periods, requiring caution. Outsourcing procedures, manufacturing-capacity contracts, corrective-action records, complaint-handling records, and supplier-assessment records are incomplete or...

Financial creditThe submitted financial slices report zero operating revenue and zero profit-related figures for the stated periods, while current ratios are also reported as zero. These figures do not demonstrate financial strength and indicate a material need for verification before relying on the supplier’s financial capacity.

R&D capabilityThe supplier reports no new product information during the past year, no ODM service, and no available SDK. Although it can customize from samples and designs, the provided evidence does not support strong independent R&D or innovation capability.

Customization capabilityCustomization from samples and customization from designs are explicitly available through both design services and R&D-related services. This supports the supplier’s ability to handle customer-specific requirements, although no evidence is provided regarding production scale or technical complexity.

Client casesThe supplier states that it has become a fixed raw-material supplier to Panasonic, Toyota, Honda, IKEA, and Komatsu, and reports that 90% of total sales are exports. These named customer claims provide positive case evidence, but the slices do not include order scope, duration, product details, or independently verifiable references.

Product Q&A

Q:What is the advantage of S460M over Q355B for a high-rise building column?

S460M hot rolled steel plate offers 460 MPa minimum yield strength compared to Q355B's 355 MPa. This 30% strength increase allows column sections to be lighter or carry higher loads, reducing structural steel weight and foundation requirements in high-rise construction.

Q:Can you provide hot rolled steel plates with Z35 through-thickness properties?

Yes, our Q420B, S460M, and Q460C hot rolled steel plates can be supplied with Z-direction tensile testing per EN 10164, achieving Z25 or Z35 quality for welded joints subject to high through-thickness loading in column base plates and bridge bearings.

Q:What surface preparation do you recommend for bridge steel plates before painting?

We recommend ordering hot rolled steel plates with a shop primer (pre-construction primer) coating for bridge fabrication. The primer provides temporary corrosion protection during fabrication and serves as an excellent base for the final paint system. Plates can also be supplied pickled and oiled or blast cleaned to SA 2.5.
