How to use Girder Couplers?

The Drop Forged Girder Coupler is designed to attach 48.3mm scaffold tubes directly to the flanges of steel beams (H-beams or I-beams). This is critical for creating suspended access platforms or hanging scaffolds where Steel Planks are needed.

Important Safety Note: A scaffolding beam clamp (gravlock) must always be used in pairs. You must place one coupler on the left side of the flange and another on the right side to ensure a secure, balanced grip. For standard 90-degree tube connections, please check our Double Couplers.

Forging Process

Our drop forged girder couplers are manufactured using automated forging lines. This process ensures high density and consistent quality for every beam clamp.

  • 🔥 Heating: Precise temperature control.
  • 📏 Testing: 100% check on bolt thread.
