Key features

Our pickled and oiled steel coil provides a scale-free surface that improves laser cutting speed and quality, while ensuring consistent robotic weld integrity without pre-cleaning.

S355MC and S420MC pickled steel offer high yield strength with excellent formability, enabling thinner-gauge automotive structural parts without sacrificing crash performance.

SPHE pickled and oiled steel coil provides the elongation and formability needed for deep-drawn automotive components, reducing cracking and scrap in high-volume stamping operations.

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 difference between HRPO hot rolled steel and mill finish hot rolled steel?

HRPO hot rolled steel undergoes acid pickling to remove the dark mill scale from the surface, followed by oiling for rust protection. The resulting surface is clean, smooth, and ready for welding or painting. Mill finish steel retains the scale and requires shot blasting before painting.

Q:Can HRPO steel be used for automotive suspension components?

Yes, S355MC and S420MC pickled and oiled steel coils in 2.0mm to 4.0mm thickness are commonly used for control arms, subframe components, and spring seats. The HSLA grades provide the fatigue strength needed for suspension parts, while the HRPO surface ensures clean stamping and welding.

Q:How long can HRPO steel be stored before rust appears?

With the protective oil coating, HRPO steel can typically be stored indoors for 2-4 months without rust. For longer storage, we recommend re-oiling or applying a heavier rust preventive. Dry storage conditions and avoiding temperature fluctuations that cause condensation will extend storage life.
