SupFRP Hollow Bolt-SupAnchor

SupFRP SDA Bolt SupFRP Hollow Bolt I  SupFRP Solid Bolt I  SupFRP Rebar

The SupFRP® GFRP Hollow Bolt is developed with high tensile load and pressure resistance. It combines rock bolt with injection function.

The GFRP Hollow Bolt can be widely applied in geotechnical engineering projects.

After injection work,the bolt can remain in the borehole and bear load with plate and nut at the end.

It has very good bonding force with all grouting materials.

Due to high injection pressure,it can realize full grouting and improve project quality.
