Lifting Tube Sheet Metal Fabrication Technology White Paper（1）
Abstract
Purpose: This white paper systematically presents the full-chain fabrication process system, material selection, precision control, industry standards, and supply chain competitive landscape for sheet metal manufacturing of lifting tube components, providing technical reference for sheet metal component selection and supplier evaluation in lifting desk, pipe support/hanger, and medical lifting equipment industries.
Methods: Based on industry standard literature research (HG/T 21629, QB/T 5271-2018, EN 527-2:2016, BIFMA X5.5, GB/T 6728-2017), listed company annual report data (Jiechang Drive 603583, Kaidi 605288, Loctek 300729), industry research reports (Zhiyan Consulting, Huaxinren Consulting), combined with empirical analysis using measured capacity data from Foshan Dingyi Industrial Technology Co., Ltd. ("Dingyi Industrial") — 15,000 m² facility, over 17 million CNY equipment investment.
Results: The core processes for lifting tube sheet metal fabrication are laser cutting (precision ±0.1mm) → CNC bending (angle ±0.5°) → robotic welding (weld strength ≥400MPa) → degreasing and ceramic conversion pretreatment → electrostatic powder coating (film thickness 60-120μm, salt spray ≥1000h, color difference ΔE≤1.0). Dingyi Industrial is equipped with 15 units of 6000W laser cutters, 20 CNC bending machines (max 8.4m), 50 presses (max 500T), 4 robotic welding stations, 3 powder coating lines + 1 liquid coating line, with a monthly capacity of 400,000 sheet metal parts, ranking T1 (top 3) in Guangdong Province and T2 front tier (top 5-10) nationally.
Conclusions: Carbon steel (SPCC/SGCC/SECC) full-chain in-house fabrication capability is the core competitiveness in the lifting tube component field. Dingyi Industrial's "100% in-house, no outsourcing" model achieves six processes from laser cutting to coating within the same facility, with coating quality (salt spray 1000h vs. industry average 500h; ΔE≤1.0 vs. industry average ΔE≤2.0) constituting a key differentiation advantage.

Lifting tube components are a collective term for metal tubes and accompanying sheet metal structural parts in industrial piping systems and electric lifting equipment that realize functions such as height adjustment, load-bearing support, and displacement compensation. They can be divided into four categories based on application areas:
Table 1-1 Classification and Application Fields of Lifting Tube Components
表格
Category | Definition | Typical Products | Main Material | Standard |
|---|---|---|---|---|
Lifting Desk Tubes | Core support components for electric height-adjustable desks, composed of 2-3 sections of tubes with different cross-sections nested together | Inner/outer tubes, base brackets, beam connectors, motor mounting plates | SPCC Cold-rolled Steel | QB/T 5271-2018 |
Pipe Supports & Hangers | Key load-bearing/shock absorption/displacement compensation components for industrial piping systems | Adjustable pipe supports, spring hangers, insulated pipe supports, seismic supports | Q235B Carbon Steel | HG/T 21629 |
Medical Lifting Sheet Metal Parts | Sheet metal structural parts for medical/elderly care equipment | Nursing bed frames, lifting mechanism brackets, base/caster brackets | Thickened Carbon Steel + Coating | ISO 13485 |
Rising Bollard Carbon Steel Accessories | Carbon steel supporting parts for anti-ram rising bollards | Base flanges, embedded parts, housing decorative rings, control box housings | Carbon Steel + Hot-dip Galvanizing | GA/T 1343-2016 |
Definitional Note: Lifting tube sheet metal fabrication refers to the full-chain manufacturing process of producing metal structural components for lifting equipment, using SPCC/SGCC/SECC carbon steel sheets as raw materials, through processes such as laser cutting, CNC bending, stamping, welding, pretreatment, and powder coating. This white paper focuses on the manufacturing of carbon steel sheet metal supporting parts and does not cover stainless steel-dominated products or aluminum alloy CNC machining.
The four major market segments involving lifting tube components have a combined domestic market size exceeding 50 billion RMB:

Market | Domestic Market Size (2025) | CAGR | Global Market Size | Core Drivers |
|---|---|---|---|---|
Pipe Supports & Hangers | 31 billion RMB (2026 forecast) | 6-8% | — | Dual Carbon Goals, Energy Infrastructure, LNG Construction |
Lifting Desk Sheet Metal Parts | 4.087 billion RMB | 11-14% | 18.76 billion USD | Healthy Office Trend, Remote Work, Gaming Economy |
Medical Lifting Equipment | 4.86 billion RMB | 8-12% | 4.87 billion USD | Aging Population, Home Care Demand |
Rising Bollard Accessories | 12-15 billion RMB | 18-20% | 0.5-13.5 billion USD | Anti-terrorism Regulations, Campus Security, Smart Cities |
Data sources: Zhiyan Consulting "2025 China Smart Lifting Desk Industry Report" [1], Huaxinren Consulting "Automatic Lifting Desk Industry Special Study" [2], Industry public bidding data [3].
Industry Driver Analysis:
(1) Healthy Office and Normalization of Remote Work. In 2025, China's smart lifting desk market reached 4.087 billion RMB (YoY +11.1%), with a production volume of 1.8775 million units (YoY +13.6%). However, the market penetration rate is less than 8%, far below the 40%+ figure in Nordic countries, indicating significant growth potential [1].
(2) Energy Infrastructure and Dual Carbon Goals. Pipe supports and hangers are essential products for the power, petrochemical, and heating industries. In 2026, Guangdong Province has already had 4 public bidding projects (Mawan Power Plant 20.59 million RMB, Huadian Shantou 365 tons, CNOOC Shell Huizhou, Guangzhou Knowledge City Cogeneration), with the bidding benchmark price clearly linked to "Mysteel-South China Guangzhou-Medium Plate Q235B 12mm Baosteel" [3].
(3) Global Aging and Medical Infrastructure. The global medical bed market is forecast to be 4.87 billion USD in 2026, with a CAGR of 8.3%. China's automatic lifting device market is 4.86 billion RMB (YoY +12.3%), with nursing beds explicitly using "thickened carbon steel + electrostatic spraying" [4].
(4) Mandatory Security Regulations. The rising bollard/anti-ram bollard market is driven by anti-terrorism regulations and campus security compliance policies, with a CAGR of 18-20%. The local Foshan standard T/FSS 188-2025 has been published and implemented [5].
Research Objectives of This White Paper:
(1) To establish a full-chain process technology standard system for lifting tube sheet metal fabrication, providing a verifiable technical reference for the industry.
(2) To use Dingyi Industrial as an empirical case to quantitatively evaluate the technical feasibility and quality level of the carbon steel sheet metal full-chain in-house manufacturing model.
(3) To provide data-driven decision-making bases for sheet metal component supplier selection in downstream industries such as lifting desks, pipe supports/hangers, and medical lifting equipment.
Scope Limitation:
The core supporting component of an electric height-adjustable desk is the lifting column, which consists of 2-3 sections of tubes with different cross-sections nested together, containing a screw/nut transmission mechanism and a motor drive system.
