Stable Heavy D28 Positioning Welding Table For Metal Workshop Fabrication
The Stable Heavy D28 Positioning Welding Table is a precision work platform engineered for metal workshops where stability and accurate fabrication are top priorities. Built with a heavy, vibration-dampening structure and a precision-machined D28 positioning grid, this table provides a rock-solid foundation for high-quality welding and assembly work.
Ideal for precision metal workshops producing everything from custom machinery to high-tolerance components, this table combines heavy construction with accurate positioning capability. The solid steel top and reinforced frame absorb vibration from welding, grinding, and hammering, while the D28 hole system delivers repeatable locating accuracy for every setup.

The heavy solid steel top combined with a reinforced box-section frame creates a massively stable work platform. This high-mass construction absorbs vibration from welding, grinding, and workpiece handling, ensuring that delicate setups and precision alignments are not disturbed during fabrication.
The precision-bored D28 holes achieve position accuracy within ±0.04 mm, thanks to state-of-the-art CNC machining and strict quality control. This level of positioning accuracy ensures consistent, repeatable fixture setups that produce dimensionally accurate parts batch after batch.
The table top undergoes precision grinding after stress relief treatment, achieving a flatness tolerance of ±0.06 mm per meter. This flat reference surface ensures that workpieces sit true and square, providing a reliable base for both welding and dimensional inspection.
Beneath the table top, a robust box-section frame with full cross bracing distributes weight evenly and prevents torsional flexing. This rigid understructure maintains table flatness and alignment even when heavy workpieces are placed off-center, contributing to consistent fabrication quality.
The working surface receives a professional nitriding treatment that creates a hard, wear-resistant layer with HV 550 to 650 hardness. This treatment protects against welding spatter, abrasion, and surface damage, preserving the table precision and making daily cleanup fast and easy.
Each support leg is fitted with a heavy-duty precision leveling foot that allows fine adjustment of table height and flatness. This ensures you can set up the table perfectly level on any workshop floor, providing a stable, accurate foundation for all your precision metal fabrication work.

- 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.
A: The stability comes from three key design features: a thick solid steel top plate that provides high mass, a heavy box-section frame with full cross bracing that resists flexing, and multiple support legs with precision leveling feet. This combination creates a rigid, vibration-absorbing platform that stays steady during all fabrication operations.
A: The D28 holes are precision-machined with a position accuracy of ±0.04 mm. This is achieved through high-precision CNC machining and verified with coordinate measuring equipment during quality inspection. The consistent grid spacing ensures your fixtures locate exactly where expected, every time.
A: Yes, the precision-ground flat surface and accurate hole grid make the table suitable for both welding and dimensional inspection. Many workshops use it as a dual-purpose station, welding components and then checking dimensions on the same surface to eliminate transfer errors between operations.
A: Nitriding creates a hard, wear-resistant surface layer that penetrates into the steel, rather than just sitting on top like a coating. This means the protection is durable and will not chip or peel off. The nitrided surface also naturally resists welding spatter adhesion, making cleanup much faster compared to untreated or painted surfaces.
A: The right size depends on your typical workpiece dimensions and available floor space. We recommend selecting a table that provides at least 200 to 300 mm of extra space around your largest workpiece to allow room for clamps and fixtures. Our technical team can help you evaluate your needs and recommend the optimal size and configuration.
A: The table is leveled using the precision adjustment feet on each support leg. A precision level or straight edge is used to verify flatness across the table surface. For initial setup, we recommend careful leveling before first use. After that, check leveling every 3 to 6 months, or any time the table is moved or experiences a heavy impact.
