Duorui Expands Export Range with Galvanized Scaffolding Couplers and Clamps for Global Construction

Duorui, a professional manufacturer of scaffolding systems and construction hardware, has expanded its export range with a complete series of galvanized scaffolding couplers and clamps. The new coupler series covers double couplers, swivel couplers, sleeve couplers, and board retain couplers, all manufactured to meet EN74 and BS1139 standards for international construction markets.

Scaffolding couplers are critical components that connect steel tubes and form the structural skeleton of tube and clamp scaffolding systems. The safety and stability of the entire scaffold structure depend on the quality and reliability of these fittings. Duorui has therefore invested in advanced forging and pressing production lines to ensure every coupler delivers consistent clamping force, precise dimensions, and long service life in demanding site conditions.

Key Features of the Coupler Series

• Drop Forged Construction: Double and swivel couplers are manufactured using drop forging technology for superior strength and fatigue resistance.
• Hot Dip Galvanized Finish: All couplers feature a hot dip galvanized surface treatment that provides excellent corrosion resistance for outdoor use.
• 48.3mm Standard Compatibility: The couplers are designed to fit 48.3mm scaffolding tubes, the international standard diameter.
• EN74 and BS1139 Compliance: Products are tested and certified to meet European and British safety standards.
• Complete Range: Right angle, swivel, sleeve, and board retain types are available for every connection requirement.
• High Clamping Force: Precision machined bolts and nuts ensure secure locking and stable load transfer.

Applications

These couplers are widely used in tube and clamp scaffolding systems for building construction, facade renovation, bridge works, industrial plant maintenance, and event stage structures. The flexible tube and clamp system can adapt to complex building geometries where prefabricated frame systems cannot fit, making couplers indispensable for specialized access solutions worldwide.
