What is a friction bolt?

Friction bolts have been used internationally in mining for decades and are considered the simplest form of ground support available in metal mining. Compression of the high tensile steel "C" shape into a hole diameter smaller than the tube generates a load transfer from the steel to the rock. A steel ring is fixed to the collar end of the tube that will retain a plate on the installed tube to establish compressive force against rock.

Available in either black or hot dip galvanised. Variety of diameters (34 mm, 40 mm and 47 mm) and various lengths from 600 mm to 3,000 mm

Used in the development and production headings for immediate support with quick and easy installation.

HIGH CAPACITY FRICTION BOLT

HCF (High-Capacity Friction) bolts are designed to deliver superior ground support in high-load environments, including, but not limited to, squeezing ground conditions.


MESH PIN

We offer Mesh Pins that improves productivity when installing mesh by reducing the number of holes to be drilled.

EXPANDABLE ROCK BOLT

The Expandable Rock Bolt (EXRB) offers fast and reliable rock reinforcement with assured quality and guaranteed mechanical properties. The EXRB consists of a folded steel tube with upper bushing and inflation bushing welded at each end of the tube.
