The D16 Series Steel Heavy Duty Assembler Fixture 3D Welding Table is a standardized flexible fixturing platform specially designed for metal welding, assembly and inspection.
Materials and Surface Treatment
Main Material
Tabletop and side panels are constructed from Q355 low-alloy high-strength steel featuring an integrated welded structure with reinforcing ribs. The underside is densely ribbed to resist deformation caused by high welding temperatures.
Standard Surface Finishes
Nitrided (Premium Model): Ion-nitrided working surface with hardness of HRC 45-52 (HV 450-630); offers excellent wear resistance, protection against weld spatter burn-in, and rust prevention.
Standard Shot-Blasted & Painted (Economy Model): Underside is shot-blasted to remove sand and relieve stress; surface is coated with anti-rust black paint.
Stress Relief Treatment
After rough machining of the steel plate blanks, the entire unit undergoes stress-relief annealing to eliminate internal welding stresses, ensuring no warping during long-term use and maintaining lasting, stable precision.
Structural Design
- Five-sided machining surface: Top and all four vertical sides feature a full grid of standard D16 holes, enabling 3D positioning
- T-slot-free design: Uniform hole standards allow for flexible fixture combinations at any location
- Reinforced base frame with adjustable support legs featuring anti-slip, vibration-dampening pads
- Side-mounted scale rulers: Precision 1mm scales etched along table edges for quick visual dimension checks

FAQ
Can I connect multiple D16 tables together?
Absolutely. We supply dedicated splicing lock pins to combine several tables into one large working platform, with overall flatness error ≤0.15mm after connection.
Do you accept OEM brand laser marking on the 3D welding table?
Yes, we can laser engrave your company logo, brand name and dimension scale on table surface without extra charge for bulk orders. Neutral no-logo package is also available.
What certificates can you provide for customs clearance?
CE mechanical safety certificate, ISO9001 quality system certificate, raw steel material test report, factory precision inspection sheet, original commercial invoice, packing list, and certificate of origin.
What's the difference between D16 and D28 welding table?
D16 adopts 50mm dense grid, more clamping points for small precision workpieces, lighter table body and lower cost; D28 is 100mm large grid, higher load capacity only for heavy thick steel structures. Our D16 steel model is ideal for most small and medium fabrication shops.
