AI-Powered supplier vetting
SummaryShanghai Strong Engineering Construction Co., Ltd. is a China-based trading company established in 2014, focused on lift accessories and related construction machinery, mechanical, electrical, and hardware products. The supplier reports five employees, overseas service limitations, no overseas warehouse, showroom, agent, or branch, and participation in bauma China. It offers customization from samples and designs but does not provide private mold development, 3D software design, ODM, OEM for popular brands, or SDK support. Product information indicates new products were developed during the past year. Service procedures and corrective-action records are documented, although the approved supplier list lacks signatures or dates. Audit information identifies TÜV Rheinland, but the evaluation result is recorded as 0 and the stated report validity ended on 2025-08-12. Production capacity, financial credibility, and customer case evidence remain insufficient for firm conclusions.
Supplier typeThe supplier is identified consistently as a trading company and limited company, with no larger-company group affiliation. Its stated scope covers lift accessories and a broad range of construction machinery, mechanical, electrical, metal, hardware, rubber and plastic, and automobile-related products.
After-Sales capabilityThe supplier reports written procedures and records for service-capability assessment, a corrective and preventive action mechanism, and ten qualified service-capability suppliers. It lacks overseas warehouses, showrooms, agents, and branches, although it has participated in bauma China and reports lead times within 15 workdays.
R&D capabilityThe supplier reports having launched new products during the past year, indicating some product-development activity. However, it does not offer ODM, private mold development, professional technical-supplier R&D, 3D software design, or SDK support.
Customization capabilityThe supplier explicitly offers customization from samples and designs. However, it does not provide private mold development or 3D software design services, so customization appears available in defined forms rather than as a full design-and-development service.
