3D Modular D28 Welding Table With Multi-Hole Grid For Repeatable Weld Positioning
Product Overview
The 3D Modular D28 Welding Table with Multi-Hole Grid is a professional fixturing solution engineered for metal fabricators who demand consistent, repeatable weld positioning across every production run. Built on a precision-machined 28mm grid hole system, this table eliminates the time-consuming process of building custom jigs for every new project -- simply insert locking pins and clamping fixtures into any grid hole to set up workpieces in minutes.
Constructed from premium Q355 structural steel with an optional nitrided surface, the D28 modular welding table delivers exceptional rigidity, flatness, and wear resistance. Its three-dimensional fixturing capability allows workpieces to be secured from the top, sides, and bottom, enabling fabricators to tackle complex assemblies, angled welds, and multi-sided projects with unmatched accuracy. Whether you produce structural steel frames, automotive chassis, or custom metal components, this table ensures every weld joint aligns perfectly, batch after batch.

Product Advantages
1. Multi-Hole Grid Enables True 3D Fixturing
The precision-drilled 28mm grid holes cover the entire tabletop and extend down all four side edges, creating a true three-dimensional work surface. Fixtures can be mounted horizontally on the top surface or vertically on the side faces, allowing you to clamp workpieces at any angle and access weld joints from all directions. This eliminates the need to flip or reposition heavy parts mid-project.
2. Unmatched Repeatable Positioning Accuracy
Every grid hole is CNC-machined to tight tolerances, delivering ±0.1mm flatness and ±0.05mm positioning repeatability. Once you establish a proven fixture setup, you can recreate it identically on future orders -- no measuring, no re-calibrating, no trial-and-error. This consistency directly reduces scrap rates, rework time, and production variability across batch runs.
3. Modular Design Saves Time and Reduces Costs
Say goodbye to building custom welded jigs for every new project. The D28 grid system works with a full library of standard fixturing accessories -- quick locking pins, clamping arms, stop blocks, angle plates, and more. Setups that once took hours now take minutes, and the same set of accessories works across every table size. Over time, this modular approach dramatically cuts jig fabrication costs and frees up workshop floor space.
4. Nitrided Surface Built for Industrial Durability
The optional gas-nitrided treatment hardens the table surface to HV 600-800, creating an integrated wear layer that resists welding spatter, abrasion, and corrosion. Unlike painted or powder-coated surfaces that chip and peel, the nitrided finish is part of the steel itself -- it will never flake off or require re-coating. Your table stays flat, clean, and precision-ready for 8+ years of heavy daily use.
Applications
The 3D Modular D28 Multi-Hole Welding Table is designed for a wide range of metal fabrication and manufacturing scenarios where repeatable precision matters:
- Structural Steel Fabrication -- Consistent setup of beams, columns, trusses, and steel frames for building construction and infrastructure projects.
- Automotive and Transportation -- Repeatable fixturing for chassis assembly, roll cages, exhaust systems, trailer frames, and vehicle customization.
- Heavy Equipment Manufacturing -- Precision assembly of agricultural machinery, construction equipment, mining components, and industrial machines.
- Robotic Welding Cells -- Serves as a standardized base for automated welding stations, ensuring every workpiece sits in the exact same position for robot path consistency.
- Aerospace and Defense Components -- High-accuracy fixturing for precision metal structures where tight tolerances and repeatability are critical requirements.
- Furniture and Metal Art Production -- Enables batch production of custom metal furniture, sculptures, and decorative pieces with consistent angles and joint fit-up.
- Pipe and Tube Fabrication -- Secure, repeatable positioning for pipe spools, tubular frames, handrails, and guardrail systems.
- Job Shops and Contract Manufacturers -- Fast changeover between diverse customer projects, reducing setup time and improving overall shop throughput.

Frequently Asked Questions
Q1: What repeat positioning accuracy can this D28 multi-hole welding table achieve?
A: The whole tabletop is CNC precision machined, with flatness tolerance ±0.1mm per square meter and positioning repeatability up to ±0.05mm. You can copy the same fixture setup repeatedly without remeasuring, ensuring consistent weld quality for mass production.
Q2: Are all D28 quick locking pins and fixtures fully compatible with this multi-hole grid table?
A: Yes. All our D28 series accessories including ball lock pins, stop blocks, angle brackets and clamping jaws match the standard 100×100mm D28 grid holes perfectly. They also fit most mainstream brands of D28 welding tables on the market.
Q3: What benefits does the nitrided surface bring to the multi-hole tabletop?
A: Gas nitriding forms an integrated hard layer with hardness HV600-800. It resists welding spatter, scratches and corrosion, never peeling or chipping like painted coatings. The table keeps stable precision and flatness after years of heavy workshop use.
Q4: Can I fix workpieces vertically on the side faces of this 3D modular welding table?
A: Absolutely. The D28 multi-hole grid extends to four vertical side panels, supporting 3D multi-angle clamping. You can mount fixtures on the top surface or side walls to lock irregular workpieces and weld all sides without flipping heavy parts.
Q5: Is custom size available for the 3D Modular D28 welding table? What's the MOQ?
A: MOQ is only 1 unit. We offer customized length, width, table thickness and adjustable leg height. We can also adjust grid layout and add special supports according to your workshop production demands.
Q6: How long is the production lead time for standard and custom D28 welding tables?
A: Standard-size tables take 15-20 working days. For custom dimensions or bulk orders over 10 sets, the lead time is 20-25 working days. We use export plywood crates with anti-rust film to avoid damage during sea transportation.
