Nitrided D28 Welding Table For Workshop Metal Welding Projects
Product Overview
This nitrided D28 welding table delivers dependable modular
positioning performance targeted at daily‑intensive workshop metal
welding projects. Built with robust cast iron base and uniform
plasma nitrided surface, the unit maintains stable flatness under
repeated clamping, fixture mounting and thermal welding impacts.
Its standardized D28 hole grid enables fast rearrangement of
assorted accessories, cutting down setup time for mixed‑batch metal
fabrication. Designed for long‑term workshop deployment, this
welding platform balances high rigidity, wear resistance and
operational flexibility to support varied metal welding and
assembly workflows.

Product Advantages
Key Features
- Superior Wear‑Resistant Nitrided Surface
The plasma nitrided tabletop resists scratches, arc burns and daily
abrasion generated in busy workshop environments. It avoids quick
surface degradation even after frequent clamping and welding
sparks, extending the service life of the whole table and lowering
your long‑term replacement expense.
Accurate Repeatable Positioning
Precision‑machined D28 hole grid ensures consistent locating
accuracy for all matched jigs, clamps and locking pins. Operators
can reproduce identical fixture setups repeatedly, which reduces
positioning errors and keeps output quality steady for serial
workshop welding projects.
High Structural Rigidity Against Deformation
High‑density cast iron main body absorbs welding stress and
mechanical pressure effectively. Heavy workloads and thermal
distortion will not easily bend or twist the table surface,
preserving reliable flatness during continuous multi‑shift workshop
operations.
Full Compatibility With D28 Series Accessories
Every hole follows universal D28 dimension standards. You can
freely combine clamps, support blocks, locating pins and angle
brackets from the D28 accessory ecosystem. Quick configuration
changes adapt the table to diverse workpiece sizes without custom
modification.
Simple Setup And Flexible Reconfiguration
No complicated pre‑adjustment is required before starting work.
Operators re‑arrange fixtures in minutes to switch between small
components and large metal pieces. This feature improves overall
workshop throughput for mixed‑order production schedules.
Low Maintenance For Busy Workshop Use
Hard nitrided surface is easy to clean after welding work. Ordinary
slag removal and surface wiping are sufficient for daily upkeep. No
frequent coating or special surface protection work is needed to
keep the table in usable condition.

Frequently Asked Questions
Q: What does D28 mean?
D28 refers to the 28mm diameter of the fixturing holes on the table surface. It's the standard
designation for heavy-duty industrial welding tables with 28mm bore
holes on a 100mm grid pattern.
Q: Is the D28 table compatible with my existing fixtures?
The D28 100mm grid is an industry standard for heavy welding
tables. If you currently use 28mm fixturing pins, clamps, or stops
with any major brand, they will work with our table. We also sell
complete D28 fixturing accessory kits if you need them.
Q: What size table should I choose?
For most structural steel shops, 2400 ×1200mm is the most versatile workhorse size. If you regularly work with
extra-long beams or large assemblies, go for 3000 ×1500mm or 4000 ×2000mm. Our team can help you size based on your typical projects.
Q: How does the nitrided surface hold up to heavy daily use?
Exceptionally well. The HV 900-1200 hardness means the surface is
5-10 times more wear-resistant than untreated steel. Shops running
2-3 shifts a day report the table looking and performing like new
after 5+ years of use.
Q: Do you have a minimum order quantity?
No MOQ for standard D28 sizes and configurations. Custom-sized
tables or special modifications are subject to negotiation —
contact us to discuss your requirements.
Q: What export documents do you provide?
We supply a complete export package, including Commercial Invoice,
Packing List, Bill of Lading, Certificate of Conformity (COC), and
any additional documentation required for your destination country.
Q: How do I place an order?
Reach out by email or phone for a formal quotation. Once you
approve the quote, confirm with a Purchase Order (PO) and we'll
schedule production immediately.
Q: Can we visit your factory?
Of course — you're welcome anytime! We'd love to show you our
production facility, nitriding equipment, and quality control
processes firsthand. Just let us know in advance and we'll arrange
a full tour.
