The Heavy Duty D28 Modular Industrial Precision Welding Fixture Platform is a next-generation solution designed for high-precision, high-load welding operations in demanding industrial environments. Engineered with a standardized 28mm diameter hole system (D28 series), this modular platform offers exceptional rigidity, repeatability, and flexibility. Whether you are welding automotive frames, construction machinery components, or heavy steel structures, the D28 platform ensures every weld is executed with micron-level accuracy.
Built from high-strength ductile iron and precision-machined surfaces, the D28 platform provides a stable and durable foundation that minimizes vibration and thermal distortion. Its modular design allows for rapid reconfiguration, making it an ideal choice for both prototyping and mass production lines.

1. What’s the difference between D28 and D16/D22?
D28 uses 28mm holes with 100×100mm grid. Designed for heavy-duty welding – higher load capacity (5 tons/m²) and better rigidity for thick plates and large workpieces.
2. Can you customize non-standard sizes or hole patterns?
Yes. Custom table sizes, hole layouts, and surface treatments are available. Send your drawings or specs, and our engineering team will design accordingly.
3. What accessories are compatible?
Full range of D28-standard accessories: clamps, V-blocks, supports, locating pins, angle plates, and adjustable brackets. All interchangeable with no special tools required.
4. How to maintain flatness over long-term use?
Stress-relieved ductile iron with HB 180–220 hardness. Keep clean, avoid local overloading. Re-machining service is available to restore precision if needed.
5. What is lead time and packaging?
Standard lead time: 15–30 working days. Packed in heavy wooden crates with anti-rust oil, VCI paper, and foam padding. Sea/air/courier shipping with full customs documentation.
6. Do you provide installation and after-sales support?
Yes – remote video guidance, online technical support, and on-site service (on request). 12-month warranty and fast reordering based on purchase history.
