Precise Drilled D28 3D Grid Modular Steel Welding Work Table
Product Overview
Precise Drilled D28 3D Grid Modular Steel Welding Work Table features fully precise CNC drilled grid holes, forming a complete 3-dimensional positioning system on the tabletop and four vertical side walls. Different from traditional single-plane welding jigs, this all-grid steel platform supports X/Y/Z multi-angle clamping, drastically cutting fixture manufacturing and workpiece positioning time.
Made of thick Q355 high-strength structural steel with complete stress relief annealing, the table delivers ultra-high flatness and outstanding impact resistance. The nitrided surface repels welding spatter, avoids rust and abrasion, maintaining long-term precision for mass production, custom metal fabrication and robotic welding lines.

Core Competitive Advantages
- Precision CNC-Machined D28 Hole Pattern: Features a standard Φ28mm hole pattern with a bore tolerance of ±0.02mm and a 100×100mm grid spacing (tolerance ±0.05mm). Laser-engraved X/Y coordinate scales along the edges allow for quick measurements without additional tools.
- 5-Sided 3D Positioning Design: The top surface and all four side faces feature the D28 hole pattern, enabling vertical, angled, and cantilevered clamping of complex frames, housings, and irregular metal parts—eliminating the need for custom, one-off fixtures.
- Heavy-Duty Q355 Steel Structure: The thickened top plate incorporates an internal rib structure, delivering a load-bearing capacity of up to 2000-3000 kg/m². It offers superior strength and toughness compared to cast iron tables—resisting brittle fracture—making it ideal for heavy machinery and chassis welding.
- Nitrided, Anti-Spatter Surface: A nitrided surface layer (hardness HV450-700) effectively prevents weld spatter adhesion, oxidation, and scratches. Spatter is easily removed without grinding or damaging the table surface, ensuring a service life of over 10 years.
- High Flatness for Precision Manufacturing: Undergoes thorough stress-relief annealing to eliminate internal machining stresses. Standard flatness is ±0.1mm/1000mm, with a premium robotic-grade option achieving ±0.05mm/1000mm, ensuring consistent dimensional accuracy across product batches.

FAQ
Q: What's the difference between D28 and D16 welding tables?
A: D28 tables adopt 28mm large locating holes with stronger clamping force and higher load capacity, designed for heavy structural parts. D16 is light-duty only for small sheet metal. Our D28 Q355 steel table resists impact better than cast iron D16 platforms.
Q: Can I connect multiple tables together for large workpieces?
A: Yes. All D28 grid positions are uniform after precise drilling. Special splicing pins are available to lock tables seamlessly, grids align completely without offset.
Q: Is the table suitable for robot welding stations?
A: Absolutely. We supply a precision grade with flatness ±0.05mm/1000mm, stable enough for automated robotic welding lines with repeated high-precision positioning requirements.
Q: Can I customize non-standard table dimensions?
A: Custom length, width and height are supported. Contact our sales team to provide your workpiece size and production demand for tailored solutions.
