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:Can you manufacture according to my drawing or specific requirements?

Yes, absolutely. We support OEM and ODM. Since expansion joints are highly customized products, we can manufacture them exactly according to your drawings, or design a solution based on your pipeline parameters.

Q:What information should I provide to get a precise quotation?

To give you the best price, please kindly provide the following details: Size (DN), Pressure Rating (PN), Material, and Connection Type.

Q:Do you inspect the products before shipping?

Yes, Quality is our culture. Every single expansion joint undergoes 100% Hydrostatic Testing (Water Pressure Test) and visual inspection before packaging to ensure zero leakage and safety.

Q:Can I get a sample to check the quality?

Yes, we can provide a standard size sample (e.g., DN100) for your evaluation. For large-size customized products, we can provide detailed production photos and videos.

Q:What certificates do you provide?

We provide the Mill Test Certificate (MTC), Material Certificate, and Hydro Test Report along with the shipment. Third-party inspection (like SGS/BV) is also acceptable upon request.
