Industrial Grade D28 Welding Table Plate with Accurate Hole Pattern
Meet your high-demand welding production with our Industrial Grade D28 Welding Table Plate with Accurate Hole Pattern. Designed for heavy-duty industrial working conditions, this welding table plate features standard 100×100mm D28 hole pattern machined by CNC gantry equipment.
Complete stress relief removes internal stress of raw materials to maintain stable dimensional accuracy after long-term repeated use. Choose between steel or cast iron substrate to match your application. Flexible fixture collocation greatly shortens tooling setup time, a fundamental work platform for modern batch welding manufacturing.

Breakdown of Stress Treatment Methods
- Steel Box-Type Welding Table Process
Steel plate cutting → Box-body welding and forming → Vibratory Stress Relief (VSR) to eliminate internal welding stresses;
Skipping the stress relief process is strictly prohibited! Without it, the tabletop will slowly warp after 2-6 months of thermal exposure, resulting in a permanent loss of flatness.
- Cast Iron Welding Table Process
Resin-sand casting → High-temperature annealing/stress relief → Secondary natural aging; dual stress-relief treatment ensures superior thermal stability compared to standard steel tabletops.
Common Issues with Inferior Market Products
Welding the box body only, without stress relief; drilling holes individually rather than using integrated gantry machining; significant hole-spacing errors and poor fixture compatibility.
Key Export Points
- Small to medium-sized tabletops: Packed in fumigated solid-wood crates that meet US and European customs quarantine requirements; edges protected with internal rubber padding; plastic plugs inserted into all positioning holes to prevent the entry of debris.
- Large welding tables (over 2000mm): Secured with steel support frames; lifting points strategically positioned to prevent bending or deformation during hoisting and transport.
- Sea freight considerations: Desiccants placed inside the crates to prevent rusting caused by high humidity during the voyage.
FAQ
Q: 2D vs 3D welding table?
A: 2D welding table only top holes; 3D welding table has holes on top and four sides for 3-way clamping.
Q: Available trade terms?
A: EXW, FOB, CFR, CIF; DDP delivery optional.
Q: Can you produce non-standard sizes, thicker plates or diagonal dense hole layout?
A: Yes. We support one-stop customization: different dimensions, increased plate thickness, internal stiffener reinforcement and diagonal dense hole pattern. Send your drawing or requirement for quotation.
Q: Are your D28 hole standards compatible with European famous brand fixtures?
A: Our hole pattern strictly follows international D28 specification. Φ28mm holes, 100×100mm grid with controlled tolerance, fully interchangeable with standard D28 clamping kits from mainstream brands.
Q: What is your MOQ for D28 welding table plates?
A: We accept 1 piece as trial order. For standard sizes, single-unit order is supported; better unit price will be offered for bulk orders. Customized sizes are also available based on project demands.
Our Industrial Grade D28 Welding Table Plate with Accurate Hole Pattern supports flexible customization and seamless matching with all standard D28 clamping accessories.
