D28 3D Welding Table with 28mm Hole and 100mm Grid Spacing Design
Are you troubled by frequent custom jig production, unstable clamping and inconsistent workpiece dimensions during heavy metal welding? Our D28 3D Welding Table with 28mm Hole and 100mm Grid Spacing is your all-in-one solution.
Adopting industry mainstream 28mm positioning holes and 100mm standard grid spacing, the 5-face through-hole structure allows flexible 3D multi-angle clamping for irregular frames, pipes and box parts. Every hole undergoes precision reaming to ensure ±0.03mm repeat positioning accuracy. The whole tabletop is treated with full stress relief and nitriding, resisting weld spatter adhesion, scratches and corrosion. It supports independent use and seamless splicing, perfectly matching small-batch multi-variety flexible production lines, widely favored by metal fabrication factories worldwide.

Core Advantages
- Cost Advantage: A single D28 welding table with a full set of tooling can replace dozens of sets of dedicated, custom-made fixtures; new product development requires no new mold or jig fabrication, resulting in long-term tooling cost savings of 70%.
- Changeover Efficiency: While traditional tooling requires 3-7 days for setup and adjustment, the D28 system allows for the positioning of new products via modular reconfiguration in just 5-30 minutes.
- Flexible Production: Perfectly suited for single-unit, small-batch, and mixed-model production; product redesigns or dimensional adjustments do not require scrapping existing tooling.
- Dimensional Consistency: Features a standardized 100mm reference grid, ensuring minimal dimensional deviation during batch welding and reducing the need for rework.
Selection Recommendations
Opt for the D28 welding table (28mm holes, 100mm grid) for large components, heavy steel structures, construction machinery, thick-plate welding, and mass production.
In contrast, choose the D16 platform (50mm grid) only for small, thin-gauge parts, precision components, and light sheet metal work.
- Q355 nitrided steel welding table: Suitable for ample budgets, applications requiring sustained high precision, and robotic welding stations.
- Cast iron welding table: Suitable for standard machine shops, environments involving heavy impacts, and moderate budgets.
FAQ
Q: Which industries are these D28 welding tables suitable for?
A: Widely used for construction machinery frames, truck chassis, railway parts, heavy steel structures, pipeline brackets, automated robot welding cells, metal cabinet manufacturing and agricultural equipment fabrication.
Q: How should I maintain the D28 welding table daily?
A: Clear welding spatter and blow out all 28mm holes with compressed air after daily work. Apply anti-rust oil if the table will be idle for over 7 days. Avoid long-time high-temperature burning on a single area and heavy hammer striking on the tabletop.
Q: What transport solutions do you offer?
A: We support FOB, CIF destination port and China-Europe railway transportation. The welding tables are packed in fumigated solid wooden cases with anti-rust paper and foam padding to prevent damage during long-distance transit.
Q: What certifications do your D28 3D welding tables have for export?
A: All tables pass CE safety certification, meeting EU metal fabrication equipment standards. We can provide commercial invoices, packing lists, certificates of origin for sea/railway customs clearance.
Q: Can multiple tables be connected to process ultra-long workpieces?
A: Yes. Special splicing plates and connecting pins ensure seamless connection. The overall flatness after splicing is controlled within 0.15mm per 2 meters, suitable for large beams, vehicle frames and engineering machinery structural parts.
