100x100 Standard Grid D28 Construction Machinery Welding Table
The 100x100 Standard Grid D28 Construction Machinery Welding Table is a professional heavy-duty 3D flexible welding table customized for the construction machinery industry. Different from light-duty D16 tables and diagonal grid tables, this D28 straight grid platform focuses on heavy load, high precision, strong stability, and mass production compatibility.
Adopting a 100mm×100mm standard straight grid and Φ28mm standard positioning holes, the table realizes millimeter-level rapid positioning. The five-sided full-hole structure allows multi-angle clamping and three-dimensional assembly, completely solving the problems of long cycle, poor versatility, and easy deformation of traditional fixed welding jigs.

Material and Craft Advantages
HT300 Gray Cast Iron Version (Most Popular for Heavy Industry)
Integral resin sand casting, high-temperature stress relief annealing and long-term natural aging treatment, completely eliminating internal stress. It has excellent shock absorption, thermal stability, and anti-deformation ability, not easy to deform under long-term welding high temperature and vibration. The surface is integrally nitrided, with strong wear resistance and non-stick welding slag, suitable for 24-hour batch production of construction machinery workshops.
Q355 High-Strength Steel Version (Super Heavy-Duty Working Condition)
Adopts thickened Q355 steel plate integral welding and overall CNC finishing, with stronger impact resistance and extreme rigidity. It is the best choice for super-large mechanical frames, thick steel plate structural parts, and frequent hoisting working scenarios.
Professional Nitriding Process
Five-sided integral ion nitriding treatment, no paint coating. The hardened layer is dense and uniform, which can resist high-temperature welding spatter, prevent oxidation and rust, avoid scratches caused by frequent clamping and workpiece dragging, and keep the table precision stable for more than 10 years.
Why Choose D28 100×100 Standard Grid (Not Diagonal / D16)
- D28 vs D16: D16 is only suitable for light sheet metal. D28 large hole system provides super clamping force and shear resistance, fully meeting the heavy load demand of construction machinery thick plates.
- Standard Straight Grid vs Diagonal Grid: Straight grid matches the right-angle positioning of mechanical frames, with intuitive scale reading and faster fixture combination. Diagonal grid is only suitable for special-shaped small parts, not for mass production of engineering machinery.
After-Sales Service
- Main table body 12-month warranty, accessories 6-month warranty
- Free technical documents: English manual, installation guide, fixture combination drawing
- Online video guidance & remote technical support
- Long-term supply of universal D28 standard accessories
FAQ
Q: What is the load capacity of the D28 welding table?
A: Uniform load: 2-10 tons/㎡. It firmly fixes thick steel plates for excavators, loaders and crane frames without hole deformation or shaking.
Q: Why is nitriding treatment necessary?
A: We adopt five-sided integral ion nitriding with 0.12-0.18mm hardened layer. The surface is slag-resistant, scratch-proof and high-temperature resistant. No paint peeling, no rust, and keeps precision stable for 8-12 years.
Q: Can multiple tables be spliced together?
A: Yes. Support seamless multi-table splicing. The overall flatness and hole coaxiality remain unified after splicing, perfect for long booms, large chassis and oversized mechanical structures.
Q: Do you support custom size and height?
A: Yes. Custom table dimensions, table height, material upgrade and laser customer LOGO etching are available. Small MOQ for custom orders, send us your workshop requirement for a free solution.
Q: Can you provide full set fixture packages?
A: Yes. We provide basic, standard and heavy-duty full accessory packages. All matched D28 tooling can be one-stop purchased to save your procurement time.
Q: What is your packaging and shipping method?
A: Standard export fumigated plywood wooden case with full foam anti-shock protection. Suitable for sea freight, railway and long-distance international transportation to avoid precision damage.
