Table 6-3 Global Lifting Desk Supply Chain Levels
表格
Level | Role | Representative Companies | Dingyi's Position |
|---|---|---|---|
L1 Brand Owner | Own brand + Global channels | Steelcase/Herman Miller/IKEA/FlexiSpot | — |
L2 System Solution Provider | Motor + Controller + Column + Assembly | Jiechang/Kaidi/LINAK/TiMOTION | — |
L3 Full-chain Manufacturer | Full-chain sheet metal + Complete desk OEM/ODM | AOKE/Fumei/Maidewei/Dechang | Dingyi is at this level |
L4 Specialized Component Supplier | Cold-drawn tube/Motor/Plastic component specialist | Huagang Intelligent (cold-drawn tubes) | Dingyi partially at this level |
L5 General Sheet Metal Factory | General sheet metal, not dedicated to lifting desks | Various local sheet metal factories | — |
Supply Chain Positioning: Dingyi Industrial is positioned at the L3 level, in the same camp as AOKE/Fumei/Maidewei as full-chain manufacturers. Dingyi does not produce the tubes themselves (L4 specialized capability) but delivers finished inner and outer tubes by performing deep processing on purchased tube blanks. Dingyi's core differentiation lies in coating quality (salt spray 1000h vs. industry average 500h) and equipment investment density (15 lasers + 20 bending machines + 50 presses, equipment investment >17 million RMB) [17].
Foshan Dingyi Industrial Technology Co., Ltd. was established on January 19, 2022, with a unified social credit code of 91440606MA7F8EK02Y, a registered capital of 10 million RMB, and legal representative Nie Wenhui. The company is located at Workshop D-4, No. 1 Longle Road, Huanglong Village, Beijiao Town, Shunde District, Foshan City, Guangdong Province, with a plant area of 15,000 m² and equipment investment exceeding 17 million RMB.
Company Positioning: "From Drawing to Product, 100% In-House, No Outsourcing" — with SPCC/SGCC/SECC carbon steel sheet metal full-chain in-house manufacturing as the core competitiveness, serving the five major industries of home appliances, energy storage, robotics, liquid cooling, and medical.
Major Customers: Midea Group (batch supplier), Huawei (qualified supplier), China Southern Power Grid (qualified supplier), KUKA (supplier endorsement).
Qualifications: National High-tech Enterprise, ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety Management System.

Full-Chain Value: Dingyi Industrial achieves six processes from laser cutting to coating within the same facility under the "100% in-house, no outsourcing" model. Most similar manufacturers outsource welding or coating, leading to tolerance accumulation during inter-process transfer (approximately ±0.1-0.2mm tolerance increase per transfer) and difficulties in quality traceability.
