AI-Powered supplier vetting
SummaryQingdao Doublegrand Metal Products Co., Ltd. is identified primarily as a manufacturer/factory of steel structures and related prefabricated building products, although another record describes the company as a trading company. The supplier states that it has exported to more than 30 countries across six continents and began exporting in 2003. Its stated capabilities include design, manufacturing, delivery, installation, and after-sales service, with production equipment, two production lines, ISO 9001 certification, and dedicated quality-control and R&D personnel. It reports substantial annual production capacity and that 90% of sales are exports. The evidence supports strengths in certification, production, customization, export experience, and service scope. Financial credibility cannot be assessed because the available registered-capital information is excluded from consideration and no other financial evidence is provided.
Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory producing steel structures, warehouses, workshops, prefabricated buildings, and related products. However, a separate company-information record describes its company nature as a trading company, creating a classification inconsistency that prevents an entirely unqualified assessment.
CertificationsThe supplier reports holding ISO 9001 certification and also states that Asia Inspection, SGS inspection, and other third-party inspections are accepted. This is explicit evidence of a formal quality-management certification and willingness to accommodate external inspection.
After-Sales capabilityThe supplier states that it provides one-stop service covering design, manufacture, delivery, installation, and after-sales service, and describes a customer-oriented professional relationship. These statements directly support the existence of an after-sales service offering, although no detailed service standards or response metrics are provided.
R&D capabilityThe supplier reports that it can develop designs independently, provide suitable proposals, and combine sales and engineering personnel to create building models and designs. It also reports 6–10 years of R&D engineer experience and advanced CNC equipment, supporting design and engineering capability, but not necessarily product or process innovation beyond customization.
Production capacityThe supplier reports more than 3,000 tons of monthly capacity, annual capacity of 200,000 tons for steel structures, 200,000 meters of galvanized wall and roof cladding, and 30,000 tons of galvanized C&Z purlines. It also reports two production lines, CNC and machining equipment, inspection at every stage, and pre-assembly before delivery, providing explicit evidence of substantial production capability.
Customization capabilityThe supplier states that it manufactures strictly according to customer drawings and requirements, can design suitable proposals independently, and performs manufacturing and inspection according to drawings. These statements directly demonstrate both drawing-based production and supplier-supported design customization.
Client casesThe supplier states that it has exported to more than 30 countries across six continents, has more than 10 years of experience, and began exporting in 2003. This supports broad international delivery experience, but the slices do not identify specific customers, projects, or independently verifiable case details.
