Core Features and Advantages
- 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.
- 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.
- 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.
- 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.
- 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.
Quality and Certification
- Material: HT300/HT250 cast iron, compliant with ISO 185.
- Process: Nitriding + Oxidation, compliant with ISO 683-15.
- Accuracy: Compliant with ANSI B5.57 and CE standards.
- Certification: CE, ISO 9001, SGS/TÜV test reports available.
Core Packaging Principles
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.
- First layer: Precision surface protection (anti-scratch / anti-impact)
- Second layer: Basic rust prevention (bonded with a nitride anti-rust layer, double protection)
- Third layer: Cushioning and vibration damping (absorbs transportation shocks, prevents structural deformation)
- Fourth layer: Rigid reinforcement (protects against heavy pressure / collisions, suitable for heavy-duty transportation)
