SummaryThe supplier is a limited company with affiliated companies, 18 employees, six production lines, and a broad product range spanning staircases, railings, doors, cabinets, bathroom products, windows, and building materials. It reports substantial stated production capacity, exports 71%–90% of sales, serves multiple international markets, and has seven years of export experience. R&D evidence is positive: new products were developed within the past year and ODM services are available, alongside extensive customization options. Production quality procedures exist, but manufacturing lacks ongoing batch quantity reconciliation. Service procedures, complaint handling, corrective actions, and supplier approval documentation are present without supporting records or complete formalization. The available audit information identifies TÜV Rheinland, but the audit result is recorded as 0 and the report validity ended in 2024; certification status cannot therefore be confirmed.

Supplier typeThe supplier is identified as a combined company and a limited company, with affiliated companies and a broad multi-category product offering. This supports classification as a diversified manufacturing and trading supplier rather than a narrowly specialized entity.
R&D capabilityThe supplier reports new products within the past year and provides ODM services, indicating active product-development capability. However, it has no available SDK, so the evidence supports product innovation and design manufacturing but not SDK-based development.
Production capacityThe supplier reports six production lines, equipment including saws, drilling, polishing, and veneer-press machinery, and stated annual outputs of 200,000 meters of railing plus 1,500 and 2,000 staircase sets. It also has standardized finished-product inspection instructions and a one-month off-peak lead time, but does not continuously reconcile quantities for each batch or mass production.
Customization capabilityBoth R&D and design-service records list customization from samples, designs, minor customization, flexible customization, and full customization. The consistency across the two slices provides explicit evidence of broad customization capability.
