Key features

Our HRPO and mill finish hot rolled steel strip is slit to exact width with tight tolerance for continuous ERW tube production, ensuring consistent forming and welding.

S355MC pickled and oiled hot rolled steel coil provides the yield strength for thinner-gauge roll-formed profiles, reducing weight in construction and racking systems.

Our Q235B and Q345B hot rolled steel meets AASHTO M180 for W-beam and thrie-beam guardrail systems, providing the strength and energy absorption needed for roadside safety.

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 hot rolled steel grade is best for ERW water pipe production?

For ERW water pipe, SPHC hot rolled steel strip in 1.5mm to 4.0mm thickness is the standard choice. It offers excellent weldability, consistent mechanical properties, and good formability for continuous tube forming and sizing operations.

Q:Can your HRPO steel strip be fed directly into a tube mill without additional surface preparation?

Yes, our pickled and oiled hot rolled steel strip has a clean, scale-free surface that can be fed directly into the forming section of the tube mill. The light oil coating provides temporary rust protection and assists with forming lubrication.

Q:What thickness and grade are standard for highway W-beam guardrail?

Standard highway W-beam guardrail uses Q235B or Q345B hot rolled steel in 2.5mm to 3.0mm thickness, produced to AASHTO M180 specification. The steel is typically supplied as slit strip and hot-dip galvanized after roll forming for corrosion protection.
