High strength DSI Combination Bolt
- Bar diameter
- 26.5 mm
- Standard length
- up to 11.8 m
- Yield strength
- 950 MPa - 524 kN
The High strength DSI Combination Bolt combines immediate mechanical anchorage with the long-term security of a fully grouted system. Its two-step installation enables fast support, flexible grouting, and durable performance with full-length corrosion protection.
Features
-
Immediate mechanical anchorage
The High strength DSI Combination Bolt is equipped with an expansion shell that enables preloading and instant support, allowing tunnel or mine headings to advance without immediate grouting.
