AI-Powered supplier vetting

SummaryQingdao Gemsun Steel Structure Co., Ltd. is a private Chinese manufacturer/factory based in Jimo, Qingdao, Shandong, supplying steel structures, warehouses, buildings, workshops, mobile houses, and related prefabricated products. It reports annual steel-structure productivity of 5,000 tons and derives 90% of total sales from exports, with exporting activity beginning in 2015. The supplier provides OEM and ODM services and supports full customization, but reports no available SDK and no new products during the past year. ISO 9001:2015 certification and recent regular fire drills are stated. Service-management documentation is weak: supplier assessment and corrective/preventive-action procedures lack written records, and complaint handling has a procedure but no written records. No overseas warehouse, showroom, agent, branch, or overseas service coverage is reported. Financial data is represented only by years rather than substantive indicators and therefore cannot establish financial credibility.

Supplier typeThe supplier is identified as a private limited company and a manufacturer/factory located in Jimo, Qingdao, China. Its stated business and product scope covers steel structures, steel buildings, warehouses, workshops, mobile houses, container houses, hangars, and prefabricated buildings.

CertificationsThe supplier states that it holds an ISO 9001:2015 certificate. This is explicit evidence of a quality-management certification, although no additional certifications are identified in the provided information.

After-Sales capabilityThe supplier reports a customer-complaint procedure, but has no written complaint records; supplier service-capability assessment and corrective/preventive-action procedures also lack written procedures or records. It has no overseas warehouse, showroom, agent, branch, or overseas service coverage, although it reports one-month lead times and participation in an offline trade show.

Production capacityThe supplier identifies itself as a manufacturer/factory and reports annual steel-structure productivity of 5,000 tons. Its broad product scope and 90% export-sales share indicate established production and export activity in steel-structure products.
