Industrial Grade D28 Welding Fixture Table with 28mm Holes
The Industrial Grade D28 Welding Fixture Table with 28mm Holes is a universal 3D flexible welding bench for industrial batch welding and inspection. Equipped with standard 28mm locating holes on all five working faces, it supports multi-angle clamping of large workpieces. With high-precision machining, strong load-bearing capacity and wear-resistant nitrided surface treatment, this D28 fixture table matches global standard D28 clamps perfectly. Multiple sizes and materials available, ideal for heavy steel frame, vehicle chassis and robotic welding workstation use.
Industrial Grade Standard Definition
Our table belongs to heavy industrial grade rather than light workshop benches:
Thickened box rib reinforced structure, heavy load up to 5 tons per square meter
Double stress relief treatment to eliminate internal stress permanently
Full 5-axis CNC precision machining with strict geometric tolerance control
QPQ salt bath nitriding hardening treatment for wear & spatter resistance
Complete CE mechanical safety certification, meets EU factory production standards
Pass full coordinate measuring machine inspection before delivery with official test reports

3D All-Side Clamping, High Production Efficiency: Five faces with D28 holes enable horizontal, vertical & angled clamping. Complete framing, welding & inspection in one single setup, no repeated workpiece flipping, cutting working hours by over 60%.
Universal Modular Fixturing, Cut Tooling Cost by 70%: One welding table matches dozens of workpieces with interchangeable D28 clamps, positioning pins, angle blocks & supports. No need to manufacture dedicated fixed jigs for new products, save material, labor and storage space.
Stable Precision & Ultra-Long Service Life: Double stress relief eliminates deformation risk. HT300 cast iron features natural shock absorption and low thermal expansion. QPQ nitrided tables maintain original flatness for 8-12 years under normal heavy industrial operation.
Fully Interchangeable with Global D28 Standard Parts: 100% consistent international D28 hole standard, perfectly compatible with Siegmund, Demmeler and all mainstream brand D28 fixtures worldwide, customers can reuse existing clamping accessories.
Multi-Scenario Multi-Process Integrated Platform: Not only for MIG/MAG, TIG, MMA welding, but also serves as measuring inspection bench, prototype assembly table and robot base datum platform, one machine covers multiple workshop procedures.

FAQ
Are your D28 holes compatible with European Siegmund fixtures?
Yes. Our 28mm hole with 100×100mm grid follows global unified D28 standard, fully interchangeable with all international D28 series clamps.
What is the difference between raw cast and QPQ nitrided surface?
Raw cast surface is low-cost without wear-resistant hardening layer. QPQ nitrided surface resists welding spatter, rust and abrasion, service life triple longer, highly recommended for export orders.
Can I get CE certificate for EU customs clearance?
All our industrial D28 welding tables are equipped with official CE mechanical safety documents, supporting smooth customs clearance in all EU countries.
What is the lead time for orders?
Standard size tables have stock, ship out within 7-15 working days. Custom non-standard sizes take 15-30 working days.
Will the welding table lose flatness after years of heavy load?
We apply double stress relief + thick reinforced rib design. After 5 years normal heavy-duty use, overall flatness deviation stays within 0.02mm.
