The precision-bored D28 holes with 100mm grid spacing deliver reliable positioning accuracy of ±0.05 mm. This means every clamp, stop, and locating pin sits exactly where expected, ensuring your welded assemblies come out square and dimensionally correct batch after batch.
Manufactured from high-grade Q355 steel with stress relief treatment, the table maintains its structural integrity and flatness over years of heavy workshop use. The robust underframe with cross bracing prevents flexing under load, giving you a consistent work surface you can depend on every day.
The working surface receives a deep nitriding treatment, creating a hard layer with HV 550 to 650 hardness. This treatment dramatically reduces wear from clamps and tools, while also making welding spatter easy to remove. The result is less maintenance, longer service life, and sustained accuracy over time.
As an industry-standard size, the D28 system works with thousands of available fixturing accessories from multiple manufacturers. You can choose from clamping bolts, angle stops, V-blocks, support brackets, and specialized tooling to match your specific fabrication needs without vendor lock-in.
The precise positioning grid eliminates guesswork and measurement errors during fixture setup. Parts are held in accurate alignment during welding, minimizing distortion and ensuring finished assemblies meet dimensional specifications. This directly reduces rework time and improves first-pass quality.
The table requires minimal day-to-day maintenance beyond routine spatter removal and periodic leveling. No specialized training is needed -- your welders can start using it effectively from day one. The simple, rugged design means fewer things can go wrong, keeping your workshop productive with minimal downtime.

D28 refers to the 28mm diameter holes machined into the table top, arranged on a precise 100mm grid pattern. The positioning system works by inserting hardened locating pins and clamping bolts into these holes to hold workpieces and fixtures in exact positions, ensuring repeatable accuracy for every setup.
The hole position accuracy is ±0.05 mm, achieved through precision CNC machining. Each table undergoes dimensional inspection after manufacturing, and we provide a factory inspection report with measured values. The grid pattern ensures consistent spacing across the entire table surface.
With normal workshop use and proper maintenance, the table typically lasts 8 to 12 years or longer. The nitrided surface significantly extends wear resistance compared to untreated steel. Actual service life depends on workload, workpiece weight, and how well the table is maintained.
Yes, the D28 system with 100mm grid spacing is an industry standard. Accessories designed for D28 holes with 100mm pitch from any reputable manufacturer will work with our table. This gives you flexibility in sourcing and allows you to use any existing D28 tooling you may already have.
Routine maintenance is minimal. Remove welding spatter regularly with a wire brush or spatter removal tool. Check and adjust table leveling periodically, especially after moving the table or if you notice any stability issues. Apply a light rust preventive coating if the table will be idle for extended periods. No complex maintenance procedures are required.
The table ships fully assembled and securely crated to prevent damage during transport. It arrives ready to place in your workshop, level using the adjustable feet, and put into production. Assembly is not required. We provide detailed leveling instructions and can offer remote guidance if you need assistance with initial setup.
