1200x2400mm | D28 Bore | Q355 High-Strength Steel – The Industrial-Grade Foundation for Precision Fabrication
Product Overview

D28 Modular Welding Table is a professional-grade fabrication workstation designed for precision, durability, and maximum versatility. Manufactured from high-strength Q355 steel (the Chinese equivalent to US ASTM A572 Grade 50 or European S355JR), this table offers superior yield strength compared to standard A36 steel.
With a 1200x2400mm (approx. 4'x8') working surface and a 28mm (D28) hole matrix, this table is the ultimate solution for heavy-duty welding, assembly, and fixturing. Whether you are building large structural frames, automotive parts, or industrial machinery, the modular 28mm system allows for rapid clamping, positioning, and repeatability.

Products Advantages
Key Features & Advantages
1200x2400mm Large Surface
Ideal for oversized workpieces, long beams, and large sub-assemblies. Provides a true flat reference plane (Flatness tolerance typically ≤0.1mm/m).
D28 (28mm) Bore Holes
High clamping force compatibility. Accepts standard 28mm modular fixturing accessories (clamps, stops, blocks, pins).
Modular Grid System
Quick changeover between jobs. Eliminates permanent tack welding to the table surface.
Through-Hole Cleaning
Debris, slag, and dust fall through the 28mm holes, making table cleanup fast and easy.
Products Maintenance
Operation & Maintenance

✅ Setup & Workpiece Positioning
Begin by placing the 1200x2400mm table on a solid, level floor. If using adjustable support legs, calibrate the surface with a precision level to ensure zero deflection across the entire 4x8 foot area. Once leveled, lay your raw materials-whether structural beams, heavy plates, or pipe assemblies-directly onto the table. Align your workpiece with the D28 hole matrix to guarantee straightness and squareness from the very first tack.

🧼 Modular Fixturing & Clamping
Unlike traditional steel tables that require destructive tack welding to hold parts in place, the D28 system uses reusable modular accessories. Insert 28mm locating pins and stop blocks into the holes surrounding your workpiece, then secure heavy-duty manual or hex clamps onto the table surface. The Q355 steel's high tensile strength allows these clamps to apply significant force without distorting the table top, rigidly locking even heavy components into perfect position for welding or assembly.

🔩 Welding, Disassembly & Maintenance
Perform your welding operations with confidence. The massive Q355 steel table acts as a heat sink, absorbing thermal energy and minimizing distortion in your finished weldment. After cooling, simply loosen the clamps and remove the finished part-no grinding off tack welds required. For cleanup, sweep slag, spatter, and dust directly through the 28mm holes into a collection tray below. The through-hole design keeps your work surface clean between jobs and extends the life of the table.

FAQ
Everything You Need to Know
Q1: Why choose the D28 (28mm) system over 16mm or 22mm?
A: The D28 system is designed for heavy industrial use. The larger 28mm holes accept bigger, stronger clamps and pins, providing higher clamping force for thick steel plates and heavy beams. It is the standard for large-format tables.
Q2:Can I use my existing 28mm clamps on this table?
A: Yes. This table follows the international standard 28mm modular system (100mm grid pitch). Any standard D28 clamp, block, or pin will fit perfectly.
Q3:Is Q355 better than standard mild steel (Q235/A36)?
A: Yes. Q355 has approximately 50% higher yield strength than Q235/A36. This means it resists hammer marks, denting, and bending under heavy loads, ensuring a flatter table for decades.
