AI-Powered supplier vetting

SummaryShanghai Baori Steel Industries Co., Ltd. is a limited company with three employees, offering Spring Steel Cold Coin and a broad range of hardware, building-material, ceramic, timber, automotive, motorcycle, and general merchandise products. It reports flexible customization and one year of export experience, but no ODM, popular-brand OEM, SDK, or new-product launches during the past year. Service coverage is limited: it has no stock, overseas warehouse, showroom, agent, or branch, and serves zero overseas countries according to the provided data. Peak- and off-season lead times are stated as within 15 workdays to one month. Quality-system evidence is incomplete, with zero listed quality-control testing equipment and unknown quality assurance and traceability status. An audit by TÜV Rheinland is recorded, but the audit result is shown as 0 and the report validity ended on 2025-10-14. No customer cases or offline trade-show participation are provided.

After-Sales capabilityThe supplier has 10 qualified service suppliers and accepts FOB, CIF, and CFR quotation terms plus LC and T/T payment terms. Nevertheless, it has no stock, overseas warehouse, showroom, agent, or branch; it has served zero overseas countries in the provided data, and its service corrective/preventive-action mechanism lacks written procedures or records.

R&D capabilityThe supplier launched no new products during the past year and does not provide ODM services, popular-brand OEM services, or an SDK. One R&D engineer is listed, but the stated responsibility is handling product photos, which does not demonstrate substantive product-development capability.

Production capacityThe supplier offers flexible customization and reports lead times ranging from within 15 workdays to one month in both off- and peak-season statements. However, it has only three employees, no in-stock capacity, zero listed quality-control testing equipment, and unknown quality-assurance and traceability status, indicating explicit production and quality-control limitations.

Customization capabilityThe supplier explicitly reports flexible customization for its Spring Steel Cold Coin offering. The provided slices do not specify customization scope, tooling, technical resources, or delivery conditions, but the stated capability is direct evidence of customization availability.

Product Q&A

Q:How do I choose between SS304 and SS316 flanges?

SS304 is standard for Food, Water, and General Chemical industries. SS316 contains Molybdenum for better corrosion resistance and is mandatory for Marine (Sea Water) and strong Acid/Alkali applications.

Q:Is the rubber joint safe for food processing?

Yes. We provide Food Grade White EPDM rubber bodies that are odorless, non-toxic, and meet sanitary standards for milk, beer, and drinking water.

Q:Can you provide the Material Test Certificate (MTC)?

Absolutely. We provide the MTC for every batch of Stainless Steel flanges, proving the chemical composition (Ni, Cr, Mo content) meets international standards.

Q:Is the flange surface rough or smooth?

Unlike cast iron flanges, our Stainless Steel flanges are CNC Machined. They have a smooth, shiny, and precise sealing surface, ensuring a perfect seal and a premium look.

Q:Can you laser mark my Logo on the stainless steel flange?

Yes! We offer Laser Marking service. We can engrave your Logo, Size, and Material grade (e.g., 'SS316 DN100') directly onto the metal flange for a professional finish.
