AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company and professional technical supplier with manufacturing, export, service, quality-control, and R&D capabilities. It provides 3D software design, sample-based and full customization, ODM, and OEM services, and reported new products within the past year. Production information includes prefabricated steel structure building capacity of 100,000 square meters, steel structure frame capacity of 5,000 tons, and other fabricated steel structure capacity of 2,000 tons. Quality credentials include CE compliance certification and ISO9001:2015 certification, supported by raw-material traceability and documented corrective-action and complaint procedures. However, the available information shows no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and no valid manufacturing-capacity contract with affiliated subcontractors. Evidence of customer cases is limited because no Fortune 500 cooperation is reported, although repeat buyers account...

Supplier typeThe supplier is explicitly described as a professional technical supplier and a combined company. Its stated business scope includes construction-related products and manufacturing/processing of doors and windows, while its profile covers manufacturing, export trade, services, quality control, and R&D.

CertificationsThe supplier reports CE certification for product compliance and an ISO9001:2015 management-system certificate. It also states that quality assurance and raw-material traceability are implemented, providing direct support for formal quality-control practices.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints, corrective and preventive actions, and service-capability assessment. It also has in-stock capacity and a stated one-month average lead time in both peak and off-season, but has no overseas warehouse, overseas showroom, overseas agent or branch, and serves zero stated overseas countries.

R&D capabilityThe supplier provides 3D software design, sample customization, full customization, ODM, and OEM services, and reports new products within the past year. However, it has no available SDK and lists only two R&D engineers, so the evidence supports active development capability but not a broad or advanced technical platform.

Production capacityReported annual capacity includes 100,000 square meters of prefabricated steel structure buildings, 5,000 tons of steel structure frames, and 2,000 tons of other fabricated steel structures. The supplier lists cutting, shearing, welding, assembly, and inspection processes, with written inspection procedures followed; however, it has no valid manufacturing-capacity contract with affiliated subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples and full customization, provides 3D software design services, and offers both ODM and OEM services. These capabilities directly indicate support for tailored product and design requirements.
