The Nitrided Surface D28 3D Welding Table with Anti-Rust Protection Layer is an industrial-grade 3D flexible welding platform designed for heavy-duty, high-load, high-wear resistance, and high corrosion resistance applications. Its core features include the D28 standard hole system, plasma nitriding, and a composite anti-rust layer. It boasts high load capacity, strong wear resistance, long-lasting rust protection, stable precision, five-sided usability, and modular assembly, making it suitable for heavy structural components, construction machinery, shipbuilding, steel structures, heavy sheet metal fabrication, and other demanding applications.

1. Heavy-Duty Load Capacity and High Rigidity
   Reinforced structure, bearing 2–3 tons/m², suitable for heavy steel structures, construction machinery, ship components, and large sheet metal parts.
2. Five-Sided 3D Flexible Clamping
   The top surface and four side surfaces are precision working surfaces with D28 positioning holes, enabling three-dimensional clamping without blind spots.
3. Nitriding + Rust Prevention Double Protection (Core Selling Point)
   Wear-resistant and durable: HV800–1200 hardness, ensuring the hole walls/table surface remain like new even after repeated clamping, welding slag impact, and workpiece friction, maintaining precision over time.
4. Modular Splicing and Expansion
   Compatible with global D28 standard fixtures (quick-release clamps, angle rulers, support blocks, V-blocks, side brackets, etc.), ensuring fixture universality and eliminating the need for customization.
5. Easy Installation and Low Maintenance
   Adjustable precision support feet at the bottom allow for installation and leveling within 1 hour, without requiring on-site modifications.

The Nitrided Surface D28 3D Welding Table with Anti-Rust Protection Layer features heavy-duty, high-rigidity construction, a nitrided, rust-proof precision surface, and modular components. Following the principles of "rust prevention as the core, damage prevention as the foundation, convenient customs clearance, and adaptable logistics," it balances protection, standardization, and practicality, making it suitable for all international transportation methods, including container shipping, international air freight, and overseas warehouse land transport.

1. First layer: Precision surface protection (anti-scratch / anti-impact)
2. Second layer: Basic rust prevention (bonded with a nitride anti-rust layer, double protection)
3. Third layer: Cushioning and vibration damping (absorbs transportation shocks, prevents structural deformation)
4. Fourth layer: Rigid reinforcement (protects against heavy pressure / collisions, suitable for heavy-duty transportation)
