Heavy Duty D28 Fabrication Table for Large Scale Steel Projects
The Heavy Duty D28 Fabrication Table for Large Scale Steel Projects offers heavy-duty rigidity and full 3D fixturing capability for oversized steel fabrications. Adopting universal D28 hole pattern, multiple tables can be connected seamlessly to handle long and heavy workpieces. Featuring wear-resistant nitrided surface and reinforced base frame, it is the ideal flexible welding solution for structural steel workshops, commercial vehicle and heavy machinery manufacturing.
Core Technology Parameters
Hole Pattern Standards Hole diameter: Φ28 mm (tolerance: +0.065 to +0.149 mm) Hole grid: 100 ± 0.05 mm; options include standard square grids or diagonally arranged high-density holes Five-sided hole design (clamping possible on the top surface and all four vertical sides, enabling X/Y/Z 3D positioning)
Two Main Material Types HT250 / HT300 Grey Cast Iron Platforms Advantages: Stable internal stress, excellent vibration damping, and resistance to deformation during prolonged high-temperature welding; suitable for high-precision, long-term, heavy-duty, and high-volume applications Q355B / S355J2 High-Strength Steel Plate Platforms Plate thickness: 24-25 mm with bottom reinforcing ribs; surface typically treated with nitriding Nitriding benefits: Surface hardness HV450+, resistance to weld spatter adhesion, wear resistance, and rust prevention
Precision Specifications Flatness: ≤0.1 mm / 1000 mm Hole center positioning accuracy: ±0.03 to ±0.05 mm Verticality (side faces): 0.1 mm / 200 mm
Load-Bearing Capacity Static load capacity per platform unit: 3-10 tons; supports modular assembly of multiple platforms to create an expansive, continuous working area, accommodating large steel beams and machine frames several meters in length.
Core Advantages
Flexible and modular design significantly reduces tooling costs - A single fixture set handles various steel components, enabling rapid changeovers and eliminating the need for traditional "one-off" dedicated welding jigs for each workpiece.
Heavy-duty rigidity suitable for large steel structures - Ensures stable clamping for thick plates, heavy frames, construction machinery chassis, container skeletons, and small bridge components; offers a load-bearing capacity far superior to D16 welding tables.
Wear-resistant nitrided surface - Resists continuous weld spatter and is highly resistant to pitting and corrosion, offering a significantly longer service life than standard painted platforms.
Infinitely expandable through modular connection - Available in standard sizes (2000×1000, 2400×1200, 3000×1500, 4000×2000 mm); multiple welding tables can be joined to accommodate the fabrication of extra-long steel structures.
Compatible with robotic welding workstations - Maintains consistent surface flatness, allowing for direct integration into automated welding production lines.
Quality Comparison
Other Suppliers
WUXI LEMAR
The mold is rough and of poor quality, with poor precision and low flatness.
Manufactured using CNC machine, the bottom is reinforced with dense and strong ribs, providing effective support for the welding table.
FAQ
Q: Can multiple D28 welding tables be connected together?
A: Yes. Units can be seamlessly spliced with standard D28 connecting pins. Holes stay aligned after assembly, allowing clamps to move freely across joined tables to create extra-large working areas for long steel beams and oversized frames.
Q: Do I have to buy the full set of clamping accessories together with the table?
A: No. You can order the bare table only, or select partial accessories. We also provide complete D28 fixture packages for one-stop procurement.
Q: How do you pack the tables for sea shipment?
A: Small units: IPPC fumigated wooden cases. Large tables: robust steel frame packaging to avoid collision during transit.
Q: Can you supply inspection reports, material certificates and CE documents?
A: Yes. Material test certificates, flatness inspection records and CE certification can be provided to meet import clearance and factory audit requirements.
