Rock Bolts


Rock Bolts

FRP Rock bolts are becoming the most common support system in the mining industry worldwide. ARC FRP rock bolt systems are being increasingly used in the coal mines in India.

ARC FRP rock bolt system offers a fully developed range of FRP rock bolts which are meant to support the modern extraction method. High tensile strength, easy handling under the most confined conditions; low weight and surface free of protruding and skin irritating glass fiber translate the same into one of the best products in the industry.

ARC FRP rock bolt systems are corrosion resistant and can be used for permanent roadway support and cater to the most aggressive environment. ARC FRP rock bolt systems offer the consulting and project engineers a useful alternative to the commonly used steel rock bolt systems.

Application :

Our FRP rock bolt systems are best suited in applications that require high tensile strength and unique features of fiber glass materials.

Our FRP bolt are intended for use in new construction in corrosive environments.

The advantage of GFRP Rockbolt applied in Coal Mine tunnel support
  • Equal strength all thread
  • High tensile strength
  • Cuttability
  • High load strength
  • Low weight, easy to handle and flexible

Traditional steel rockbolt system is widely applied in coal mine supporting construction design, this system mostly applied as temporary support mesure.

All-thread Glass Fiber Reinforcement Polymer (GFRP Rockbolt) series product not only open the possibility of new design, but also provide a very beneficial substitution for traditional engineer steel rockbolt system.
