Virsbolt Face Plates
Select a Language
General Product Description
Virsbolt face plates are used with Virsbolt expandable rock bolts.
Virsbolt face plates create local surface support around the borehole where the Virsbolt expandable rock bolts are installed. The face plates are used to transfer the displacement of the rock mass into the rock bolt. Virsbolt face plates are used for tunneling, construction, and mining.
Advantages of using Virsbolt:
-
Provides immediate and full support action
-
Accommodates large rock movements and still maintains its high load-bearing capacity
-
High deformability to accommodate ground movements in tension as well as in shear
