Ductile Iron Scaffolding Castings – High-Strength Nuts & Screw Nuts for

As a trusted manufacturer of high-integrity metal castings, we offer a full range of ductile iron (nodular cast iron) scaffolding components, engineered to meet the rigorous demands of modern construction, infrastructure, and industrial support systems. Our product line includes scaffolding nuts, screw nuts (also known as acorn nuts or tie rod nuts), base plates, brackets, couplers, and other critical cast fittings—all precision-cast for strength, reliability, and long-term performance.

Our ductile iron scaffolding castings are categorized based on function and system compatibility:

1. Load-Bearing Nuts & Screw Nuts: Designed for threaded rods, shoring posts, and tie systems. These include hexagonal, square, and acorn-style nuts with internal threads (typically M16–M48 or custom sizes).
2. Base & Sole Plates: Provide stable footing for vertical standards on uneven or soft ground, distributing load evenly to prevent sinking or tilting.
3. Brackets & Beam Supports: Used in formwork and suspended scaffolding to anchor horizontal members securely.
4. Adjustable Base Jacks & U-Head Components: Often paired with screw nuts for height fine-tuning in slab support and falsework systems.
5. Custom Structural Fittings: Tailored connectors, clamps, and adapters for specialized scaffolding or modular support frameworks.

All components are manufactured from high-grade ductile iron, commonly QT450-10, QT500-7, or QT600-3 (equivalent to ASTM A536 Grade 65-45-12 or EN 1563 EN-GJS-500-7), offering an optimal balance of tensile strength (>500 MPa), elongation (>7%), and impact resistance—far superior to gray iron or standard carbon steel in fatigue-prone environments.

Our ductile iron scaffolding castings are widely deployed across:

• Commercial & Residential Construction: For tube-and-coupler, frame, and modular scaffolding systems.
• Bridge & Tunnel Projects: Where safety, load capacity, and corrosion resistance are critical.
• Formwork & Shoring Systems: Supporting concrete pours in high-rise buildings, dams, and industrial facilities.
• Industrial Maintenance Platforms: In power plants, refineries, and shipyards requiring durable, non-sparking components.
• Event & Temporary Structures: Stages, lighting towers, and exhibition rigs needing quick assembly and reliable hardware.

Thanks to their excellent vibration damping and wear resistance, ductile iron components significantly reduce maintenance frequency and replacement costs compared to welded or forged alternatives.

Every casting undergoes rigorous quality control—from raw material spectrographic analysis and mechanical testing to dimensional inspection and visual defect screening. We comply with ISO 9001 standards and provide full material test reports (MTRs) upon request.

To enhance durability in harsh environments, we offer multiple surface treatments:

• Hot-dip galvanizing (per ISO 1461 or ASTM A123) for maximum corrosion protection
• Zinc plating for indoor or mild-exposure applications
• Painting or powder coating for color coding or aesthetic integration
• As-cast (black finish) for cost-sensitive projects with protective storage

• ✅ Superior Mechanical Properties: Higher ductility and toughness than gray iron—resists cracking under dynamic loads.
• ✅ Precision Casting: Consistent geometry ensures smooth threading and secure fit with standard scaffolding rods.
• ✅ Global Compliance: Meets or exceeds international material and safety standards (ASTM, EN, BS, DIN).
• ✅ Customization Support: From prototype to mass production—we work from your CAD drawings, samples, or technical specs.
• ✅ Scalable Supply: Reliable production capacity for both small batches and large-volume orders, with competitive lead times.

Trusted by contractors, scaffolding rental companies, and engineering firms across Europe, North America, the Middle East, and Asia, our castings deliver unmatched value in safety, longevity, and total cost of ownership.
