Hollow Wall Anchors 38mm Underground Rock Bolts
Features
The SupFRP® GFRP Hollow Bolt is developed for strata support in mining and tunneling as well as for slope and face stabilization.
is developed with high tensile load and pressure resistance. Due to high injection pressure,it can realize full grouting and improve project quality.
Applications
1. Permanent application
2. TBM face support
3. Forepoling
4. Confined ground conditions
5. Stabalization of soft rock
Advantages
1. Easy handling due to low weight
2. High tensile load
3. Good bond force
4. Cuttability
5. High corrosion resistance
