AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and limited company with associated companies, offering a broad range of bridge, rubber, sealing, and customized products. It reports 10 production lines, defined product output, six to ten quality-control staff, and export experience of 10 years, with exports representing 41%–50% of total sales. The supplier provides extensive customization and ODM services and reports new products during the past year. However, no supplier-management-system certification is reported, and its service-capability procedures lack written records for assessment and corrective/preventive actions. Complaint handling has a clear procedure with follow-up records. The supplier has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be assessed from the available non-financial information.

Supplier typeThe supplier is explicitly classified as a factory and limited company, with associated companies and manufacturing as the industry of those companies. This supports direct manufacturing status rather than a trading-only profile.

CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided for this field, indicating a stated lack of supplier-management-system certification.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with follow-up records, which is positive evidence for after-sales issue management. However, assessment and corrective/preventive-action procedures have no records, so the service system is only partially documented.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active product-development capability. However, it reports no available SDK, which limits evidence of software-development or integration capability.

Production capacityThe supplier is a factory operating 10 production lines, with six to ten quality-control staff and stated output across rubber culvert balloons, seismic isolation bearings, waterstops, and expansion joints. It also reports inspection instructions that are uniformly followed, supporting established production and quality-control operations.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, including made-to-order products with complex profiles and different materials. It also provides ODM services, demonstrating broad customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-case category. No customer names, project details, volumes, or independently verifiable case documentation are provided.

Product Q&A

Q:How does the waterstop work?

Upon contact with water, the strip swells rapidly to 2-6 times its original volume, forming a gel-like elastic body that plugs leakage paths in concrete joints.

Q:What are the available sizes?

Widths range from 10mm to 50mm and heights from 10mm to 60mm. Other specifications can be customized according to customer needs.

Q:Can the color be customized?

Yes, standard colors are black and red, but other colors can be customized to meet specific project requirements.

Q:What is the expansion rate?

The expansion rate varies by type, ranging from 150% to 600%, with options for slow-swell types to prevent displacement before concrete pouring.

Q:Is the product safe for use?

Yes, it is non-toxic, age-resistant, and produces no leachate, ensuring stability even after long-term immersion.
