Product Description
FRP rockbolts are made from high strength glass fiber and polyester resin, vinyl easter resin and epoxy resin by pultrusion and winding process.

Jinglue produces FRP rockbolts according to her own enterprise standard which is superior to Chinese National Standard. With good technology, Jinglue can produce high quality rock bolts which can meet different requirements.

In comparison with steel rockbolts, FRP rockbolts have many advantages. Step by step, FRP rockbolts replace the steel rockbolts and are widely used in some area as strata support, especially in corrosion area like mining and tunnelling, subway, etc.

1. Low weight and high strength
FRP rockbolts have double the strength of standard steel, but only a quarter of the weight. The low weight facilitates handling. The FRP rockbolt is produced using high quality fibres, with a high fibre content of approximately 80%. The fibers are embedded in either a polyester or winylester or epoxy resin matrix. This gives the rod a high tensile strength prominient in the longitudinal directions.

2. Corrosion-resistance
FRP rockbolts are corrosion resistant and therefore the only currently available system which can be regarded as permanent, even under difficult conditions with aggressive water and rock deformations. These products are used more and more increasingly for soil reinforcement and ground anchoring.

3. Excellent cuttability
FRP rockbolts are easy to cut and that can help to protect the toolbit of coal cutter.

4. Anti-static conditioning (optional)
For application in tunnelling and mining an anti-static coating can be applied as an option to avoid any sparks in explosive environment.

5. Continuous threaded profile
Due to its continuous thread profile, the FRP rockbolts offer a maximum bondage with all the grouting material and also concrete. The continuous thread profile has a great possibility to connect with couplers in any length and also can take high ultimate load.

6. High end loading
The special thread profile and an optimized matching between bolt thread and nut thread ensure high end loads that can almost reach the level of steel anchor systems.

The diameter of frp rockbolts are 18mm, 20mm, 22mm, 24mm, 26mm, etc.

In all, FRP rockbolts are best suited in applications that require high tensile strength and the particular properties of fiberglass materials. Applied correctly they contribute substantially to the reduction of project cost.
