AI-Powered supplier vetting

SummaryWuhan Dachu Traffic Facilities Co., Ltd. is a guardrail and steel-related manufacturer with design, development, production, sales, and engineering-solution capabilities. Evidence indicates five production lines, stated guardrail output of 90,000 tons and guardrail-post output of 10,000 tons, broad export-market coverage, and ports near Qingdao and Tianjin. The supplier supports multiple customization modes, ODM, OEM for known brands, and an SDK. It holds ISO9001:2015, ISO45001:2018, ISO14001, and CE-related certifications. Written procedures and records are reported for supplier-service assessment, corrective and preventive actions, and complaint handling. However, the supplier lacks a valid contract with related subcontractors, has no overseas warehouse or showroom, and provides no specific customer names or verifiable case details. Financial-period information is present, but no non-monetary evidence establishes financial strength or credibility.

Supplier typeThe supplier is identified as a manufacturer and seller of guardrails, original steel, electric-power-related equipment, and associated metal and plastic products. Its stated activities include design, development, production, sales, and engineering-solution consulting, supported by five production lines and factories covering 50,000 square meters.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, together with CE product-compliance certification. These are explicit certification holdings, although the slices do not provide certificate validity dates or scope details.

After-Sales capabilityThe supplier reports written procedures and followed records for service-capability assessment, corrective and preventive actions, and effective customer-complaint handling. This directly supports a documented service-management process, though no specific response times or service outcomes are provided.

R&D capabilityThe supplier reports new products during the past year, ODM services, an available SDK, and design and development capability. Its company description also states that its guardrail forming line uses automation and intelligence, providing explicit evidence of development and technical capability.

Production capacityProduction evidence includes five lines, stated annual output of 90,000 tons for guardrails and 10,000 tons for guardrail posts, automated guardrail forming equipment, inventory capability, and lead times within 15 workdays in both peak and off-peak service data. A deficiency is that no valid contract exists between the factory and related subcontractors, creating a documented manufacturing-governance weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, indicating support for both customer-specified and supplier-developed designs.
