It operates two production lines, reports output for high-speed PVC doors, high-speed spiral doors, and dock levelers, and has 11–20 quality-control staff, including 13 inspectors in one record. Quality inspection instructions are reportedly standardized. The supplier has in-stock capability and defined service quotation and payment terms, but lacks overseas agents or branches, overseas warehouses, overseas showrooms, and offline trade-show participation. No valid manufacturing-capacity contract with related subcontractors is reported. Financial records are referenced for 2022–2024, but no financial figures or performance details are provided. No SDK is available, and no customer cases are identified.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated scope includes communication equipment, smart-home devices, molds, office supplies, metal products, and bearings, while its facilities and industry experience cover entrance-related products.

R&D capabilityThe supplier reports professional technical R&D capability, 3D software design services, and over 20 years of industry expertise with a dedicated R&D team. Conversely, no SDK is available, so the evidence supports general product-development capability but not SDK-based integration capability.

Production capacityThe supplier operates two production lines and reports annual output of 10,000 high-speed PVC doors, 12,000 high-speed spiral doors, and 10,800 dock levelers. It has production facilities in Wuxi, Dongtai, and Thailand, but no valid manufacturing-capacity contract with related subcontractors is reported.

Customization capabilityBoth R&D and design-service records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. This directly supports broad customization capability.
