Composite rock bolts


Our composite rock bolts (rods and profiles) are used to help stabilize earthworks and mining operations.


They act as anchors to hold and help prevent unwanted movement of mine walls and ceilings.


They are versatile solutions to many anchor needs in mining, and simple to use: they can be cut to length using standard tools.


Composite versus steel


There are several benefits that composites provided, compared to steel.

  • Maintenance free (will not rust or corrode)
  • Will not fracture or become brittle at low temperatures
  • Transparent to electrical, magnetic, electromagnetic, and gamma ray analysis
  • Easily cut with standard tools
  • Rough surfaces that promote adhesion with grout and resins
