Description

Glass Fiber Reinforced Polymer 22mm Hollow Anchor Rock Bolts

Features

The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. It combines rock bolt with injection function. Due to high injection pressure,it can realize full grouting and improve project quality. After injection work, the bolt can remain in the borehole and bear load with plate and nut at the end.

Applications

1. Slope stabilization
2. TBM face support
3. Stabalization of soft rock

4. Confined ground conditions
5. Forepoling

6. Permanent application

Advantages

1. Good bond force

2. Easy handling due to low weight

3. High tensile load

4. Cuttability

5. High corrosion resistance

6. High pressure resistance
