TRM manufactures high-performance Friction Bolts designed for underground mining, tunnel reinforcement, and rock stabilization applications. Engineered for reliable ground support, our friction rock bolts provide immediate radial pressure against rock walls, improving safety and long-term structural stability in demanding environments.
As a professional friction bolts manufacturer and industrial supplier, TRM delivers durable support solutions for mining contractors, tunneling companies, and infrastructure projects worldwide.
Friction Bolts are steel tubular ground support systems installed into pre-drilled holes slightly smaller than the bolt diameter. Once inserted, the steel tube compresses and creates continuous frictional resistance against the rock surface, generating immediate support without requiring complex tensioning systems.
Widely used in underground excavation and rock reinforcement projects, friction rock bolts are known for:
● Fast installation
● Immediate load-bearing support
● High adaptability to unstable rock conditions
● Reduced installation time
● Cost-effective underground support
TRM friction bolt systems are manufactured using high-strength steel materials to ensure reliable performance in harsh mining and tunneling environments.
TRM Friction Bolts are widely used across various underground and civil engineering industries.
Underground Mining：Used for immediate rock support in underground mining tunnels, shafts, and stopes where rapid installation and safety are critical.
