Duty cycle
State whether the table is used occasionally, every day or across multiple shifts so surface wear can be judged realistically.

Surface decision
Specify nitriding when the hole grid is a daily-use interface
A nitrided table starts as the same machined steel platform. The treatment is applied after the working faces and hole grid are machined, so the hardened case protects the dimensions that clamps, pins and parts contact most often. It is a surface-life decision, not a different hole system or a substitute for choosing the correct flatness.
Choose it for a production station where tooling is inserted, removed and tightened every shift, or where parts regularly slide across the working faces. For occasional light work, a plain machined surface with normal maintenance may be the more economical specification. The workpiece, duty cycle and cleaning routine should decide the treatment before quotation.
Contact pattern
Identify whether most wear will occur at the top grid, side faces or repeated clamp and pin locations.
Treatment scope
Confirm which working faces and holes require plasma nitriding and whether another finish is needed on the support structure.
Hardness and geometry
Specify the required flatness and hole system separately; BECO nitrided surfaces are available in the verified HV450 to HV630 range.
In production
Machined, checked, then packed for export
Working faces are machined and measured before the platform is packed in a crate. The hole grid and flatness are verified so the fixtures you buy later fit the table you already have.

Nitrided Steel 3D Welding Table in the works
Built to order, so the table you receive follows the drawing and hole system you confirm.
Hole systems
D16, D22 or D28: pick the grid around the work
The hole system sets how much holding force the table gives you and how fine the positioning is. It is the first decision, because every clamp, pin and stop has to match it.
D16 welding table system
- Hole diameter
- Ø16 mm
- Grid
- 50 mm
- Best for
- Light to medium parts, jigs, frames and detail work
D22 welding table system
- Hole diameter
- Ø22 mm
- Grid
- 100 mm
- Best for
- General fabrication where one table covers several job sizes
D28 welding table system
- Hole diameter
- Ø28 mm
- Grid
- 100 mm
- Best for
- Large fabrications, thick plate and heavy welded structures
What actually changes between the series
Larger holes take larger pins and clamps, so a D28 table holds heavy structures more securely. Smaller holes let you place stops closer together, which helps small parts and tight geometry. The machined grid, hole spacing and flatness are set at the same time, so tell us the workpiece and we will match the system to it.
- Grid spacing confirmed against the drawing
- Plain bore matched to the selected system
- Flatness from 0.1 mm/m² down to 0.02 mm/m²
Questions
Nitrided Steel 3D Welding Table questions
If your question is not here, send it over — practical answers are usually faster than a specification sheet.
- What does nitriding do for a welding table?
- Nitriding is a heat treatment that diffuses nitrogen into the steel surface. It produces a hard, wear-resistant layer without a coating that can flake off. On a welding table this protects the machined faces and the hole grid where clamps and pins are used every day, so the table holds its accuracy for longer.
- Is a nitrided table better than a plain machined table?
- Nitriding costs more, so the choice depends on how hard the table will be used. For a table used daily with frequent clamping, the wear resistance is usually worth it. For occasional light work, a milled or ground surface is sufficient. We will advise based on your production volume.
- Does nitriding change the hole size or the grid?
- No. The hole grid is machined first and the nitriding treatment follows, so the holes and grid keep their dimensions and stations. Tables are available in D16, D22 and D28 hole systems.
- Will the dark surface mark the workpiece?
- No. Nitriding changes the surface of the steel itself rather than adding a paint or coating layer, so there is no film to transfer to the part. The darker surface also reduces glare under workshop lighting.
