Glass Fiber Coupler
A Non-Metallic Coupling Solution for GFRP Rock Bolting Systems
Rayon Glass Fiber Coupler is a new composite coupling solution developed for joining GFRP rock bolts. Designed to complement GFRP bolting systems, it provides a non-metallic approach to bolt extension and connection.
Designed for GFRP Rock Bolting Systems
GFRP rock bolts are used for ground reinforcement in applications such as mining, tunneling and slope stabilization. When longer bolt lengths are required, couplers are used to connect individual bolt sections.
Steel Coupler
Conventional GFRP rock-bolt systems may use steel couplers to connect and extend GFRP bolt sections.
Glass Fiber Coupler
Rayon is developing a glass fiber coupler to provide a non-metallic connection solution for GFRP bolting systems.
