Complete Range of Ductile Iron Scaffolding Castings – Nuts, U-Heads, Base Plates & Custom Fittings for Construction Support Systems

As a leading manufacturer of high-performance metal castings, we offer the most complete portfolio of ductile iron scaffolding components on the market—engineered for strength, reliability, and seamless integration into modern shoring, formwork, and access systems worldwide. From critical load-bearing nuts to specialized structural fittings, our product line covers every essential category required by scaffolding contractors, rental companies, and construction engineers.

We understand that different projects demand different hardware. That’s why we’ve developed a fully categorized casting system to meet diverse technical requirements:

1. Adjustable Nuts & Screw Nuts

   High-strength threaded components including acorn nuts, hex nuts, and square nuts in sizes M16–M48. Designed for use with base jacks and U-heads, these QT500-7 castings deliver smooth rotation, precise height adjustment, and long-term thread integrity under heavy loads.

2. Base & Sole Plates

   Robust base plates (round, square, or custom-shaped) that distribute vertical loads evenly on soft or uneven ground. Available with or without central holes for tie rods, and offered in galvanized or painted finishes for enhanced durability.

3. U-Heads, Fork Heads & Top Supports

   Essential for slab formwork and falsework systems. Our U-head castings feature reinforced arms and consistent opening dimensions to securely hold timber or steel bearers—ideal for bridge decks, high-rise floors, and industrial platforms.

4. Structural Brackets & Beam Supports

   Including cantilever brackets, transom end caps, and ledger sockets. These components enable rapid assembly of modular scaffolding frames while maintaining structural stability in complex geometries.

5. Bracing & Diagonal Connection Fittings

   Specialized cast end pieces for diagonal braces and cross-bracing systems, ensuring secure angular connections that resist lateral forces during high-wind or seismic conditions.

6. Custom & OEM Castings

   Beyond standard items, we excel at producing tailored scaffolding fittings based on your drawings or samples—whether it’s a unique coupler body, a climbing scaffold guide bracket, or a project-specific adapter.

All components are cast from high-grade ductile iron (QT450-10 / QT500-7 / QT600-3), equivalent to ASTM A536 Grade 65-45-12 or EN-GJS-500-7, delivering:

• Tensile strength ≥500 MPa
• Elongation ≥7%
• Excellent impact resistance and fatigue performance

Produced via resin sand or shell molding processes, our castings feature dense microstructures, minimal porosity, and dimensional accuracy up to CT8–CT10 (ISO 8062). Every batch undergoes rigorous testing, including spectrographic analysis, tensile trials, and visual inspection.

To suit varied climates and project durations, we offer multiple corrosion-protection options:

• Hot-dip galvanizing (per ISO 1461 / ASTM A123) – ideal for coastal or outdoor use
• Electro-galvanizing – cost-effective for indoor applications
• Powder coating or painting – for color-coded systems or aesthetic requirements
• As-cast finish – for economical short-term projects

Our comprehensive scaffolding castings are deployed in:

• High-rise residential & commercial buildings (Asia, Middle East)
• Bridge and tunnel infrastructure (Europe, North America)
• Petrochemical plant maintenance platforms (GCC countries)
• Temporary event structures (stages, lighting towers worldwide)

With ISO 9001 certification, full material test reports (MTRs), and compliance with EN 1563, ASTM A536, GB/T 1348, we ensure every component meets international safety expectations.
