FRP Rockbolts are installed as a permanent support, firstly in the tunneling projects. The systems are bonded to the concrete substrate just as with steel plates, but the FRP systems are much lighter and do not require welding. The advantage of this system is that it may be formed in place around any surface shape. The FRP rockbolt system has become a successful adoption in many applications, like;
- Mining (hard rock, salt)
- Civil engineering
- Concrete reinforcement
- Tie backs
- Ground stabilization
- Temporary ground support
- Permanent ground support
Products’ foremost features;
- Easy cutting, rod body plays a role of protection in coal mining head.
- Flame retardant, antistatic, safety in process, does not produce sparks when cutting, very safety to use in tunnel construction, especially suitable for gas region. Tensile strength of rod body is very strong and is better than the equivalent diameter of reinforcing steel bar.
- This product is light in weight, easy to operate, only a quarter of steel weight on same specifications and more easy during construction, so as to reduce workers' labor intensity,
