Product Detail Advantages
--See It In Action--
1. Precision-Ground Hole Walls
• The hole walls are smooth and burr-free, featuring a U-shaped or tapered countersink design for quick insertion of locating pins, while effectively preventing iron filings from getting stuck.
2. Stiffener Grid Structure
• The backside adopts a honeycomb or grid stiffener design, which ensures no deformation under heavy loads while reducing weight.
3. High General Interchangeability
• Fully compatible with the 3/4" fixture systems of mainstream brands (e.g., Siegmund, Demmeler, Bluco). Your existing quick-locking pins, try squares, and support rods can be used plug-and-play.
4. Quick-Cleaning Design
• Through-hole design allows iron filings to fall directly through, enabling instant cleaning of the worktable with an air gun to maintain a tidy working environment.
Application Area
1. Steel Structure Welding
Used for the precise positioning and welding of large structural components such as building steel beams and equipment frames, effectively controlling welding deformation and ensuring consistent frame diagonals.
2. Pipeline and Flange Installation
Quickly fix pipe supports and flanges using the platform holes, ensuring the verticality and axis alignment of pipe fittings for accurate tack welding and assembly.
3. Automated Equipment Manufacturing
Suitable for the assembly of robot bases, conveyor line supports, and non-standard automated equipment. The platform is reusable, ensuring consistency across multiple batches of products.
4. Automotive Manufacturing and Tooling
Used for the trial production of body-in-white samples and the welding of complex curved pipe fittings such as exhaust pipes and roll cages. With 3D fixtures, spatial angle positioning can be easily achieved.
5. Mold Maintenance and Inspection
Serving as an overhaul platform for large molds, it uses precise holes to fix, measure, and perform local welding repairs on molds. The table surface is flat and resistant to heavy impacts.

FAQ
Q1. Why is the hole spacing of this platform 3/4 inch?
A:3/4 inch (19.05mm) is the internationally accepted standard for heavy-duty welding tables, compatible with most mainstream fixture accessories on the market (such as Siegmund, Demmeler, etc.), eliminating the need for custom-made fixtures.
Q2. How heavy a workpiece can the table surface support?
A:Depending on the thickness and material of the table surface, the load-bearing capacity typically ranges from over 1000kg to 5000kg. For specific load-bearing values, please refer to the technical parameter table for the corresponding size.
Q3. Will the platform rust after long-term use?
A:The surface of the platform is treated with nitriding hardening or anti-rust oil coating, providing a certain level of rust resistance. It is recommended to clean iron filings after daily use and apply anti-rust oil regularly to maintain good condition for a long time.
Q4. Can non-standard sizes or hole diameters be customized?
A:Yes. We support customization of length, width, thickness, as well as non-standard hole diameters (such as 16mm, 22mm, 28mm, etc.), with a delivery time of generally 15–20 days.
Q5. Do the matching fixtures need to be purchased separately?
A:Yes, the platform and fixtures are usually sold separately. We can provide you with a complete set of 3/4" hole diameter fixtures, including quick locking pins, try squares, supporting angle irons, etc.
