Ultimate Strain 2.0% Length 3m 7m 11m Hollow Threaded GFRP Rock Bolts

SupFRP glass fiber reinforced polymer 22mm to 38mm hollow threaded rock bolts

Features

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

Applications

1. Slope stabilization
2. TBM face support
3. Forepoling
4. Confined ground conditions
5. Stabalization of soft rock

6. Permanent application

Advantages

1. High pressure resistance

2. Easy handling due to low weight

3. High tensile load

4. Cuttability

5. High corrosion resistance

6. Good bond force
