If your metalworking workshop has long been plagued by distorted welding tabletops, slag corrosion, unstable positioning accuracy and excessive costs for custom tooling fixtures, our D28 heavy-duty nitrided steel 3D modular welding table provides the ultimate upgrade solution.
Conventional mild steel welding tables wear out rapidly under daily working conditions including welding high temperatures, scratches and slag erosion. Flatness deviation and positioning failure tend to occur within 1 to 2 years. Our nitrided welding table is made of premium Q355 structural steel with full-depth integral nitriding treatment, paired with the universal D28 3D modular grid design. It delivers micron-level repeat positioning accuracy, outstanding wear and impact resistance, and five-sided clamping compatibility.
Developed for professional metalworking factories, custom sheet metal workshops and industrial manufacturing plants, this D28 nitrided steel welding table eliminates repeated tooling fabrication waste, cuts equipment setup time by over 60 percent, and maintains consistent machining precision year-round.
This industrial-grade nitrided welding table integrates three core strengths: high-strength Q355 steel substrate, full-surface deep hardening via nitriding, and standard D28 100mm grid 3D modular system. The whole production strictly complies with ISO9001 precision manufacturing standards.
The highlight of this nitrided welding table lies in its five working surfaces (top surface plus four vertical sides) of thickened Q355 steel covered with dense deep nitrided layers:
- Surface hardness reaches HV 450-1000, 5-10 times that of regular steel
- 0.1-0.5mm dense nitrided diffusion layer bonds seamlessly with the steel base
- Ultra-low thermal expansion coefficient prevents flatness deviation
- Tabletop flatness tolerance ≤0.1mm per meter; perpendicularity tolerance ≤0.1mm per 200mm
- Optional tabletop thickness: 24/27/30mm with maximum static load capacity of 12 tons
- Standard 28mm D28 holes with uniform 100±0.05mm grid spacing
- Five-sided through-hole design allows multi-angle clamping and positioning
- Expandable modular design supports multiple tables jointed together
- Retractable adjustable support legs with standard leveling feet
- Multiple standard dimensions available with non-standard custom sizes supported
- Metric scales laser-etched along table edges for quick measurement
- Greatly cut long-term maintenance and equipment replacement costs
- Stable welding precision and lower product rejection rate
- Markedly improved workshop productivity
- Compatibility with all metal processing sectors
- Automotive Manufacturing: Welding of vehicle frames, chassis and new energy battery brackets
- Construction Machinery: Assembly and welding of loader supports and hydraulic equipment structures
- Custom Metal Workshops: Stainless steel hardware, metal artworks and equipment prototypes
- Pipeline and Energy Industry: Prefabrication of large pipe fittings and small wind power structural parts

Tabletop: The main welding table body is packed in a heavy-duty, fumigation-free solid wood plywood crate, featuring internal foam protection and reinforced corner bracing to prevent damage during ocean transit.
Fixture Kit: Components are individually wrapped in anti-rust paper and organized within a metal tool case.
Legs and Accessories: Packed in separate boxes to prevent scratching the nitrided tabletop surface during transport.
In the fiercely competitive metalworking industry, consistent machining precision and low long-term equipment operation costs form the core competitiveness of every workshop. Our D28 heavy-duty nitrided steel 3D modular welding table is far more than a regular workbench — it is high-precision core production equipment supporting sustainable enterprise growth.
Unlike ordinary tables that lose precision quickly after short-term use, this professional nitrided welding table combines heavy steel frame construction, wear-resistant deep nitriding hardening treatment and universal D28 modular fixture systems, solving all pain points of traditional welding benches at once. We provide full customization for table dimensions, leg styles and matched tooling sets. Each nitrided welding table comes with complete CAD drawings, operation manuals and a 12-month structural warranty.
