High strength FRP rock bolts
Compared with aluminum or steel, glass fiber reinforced plastics (GRP) have advantages that can be traced to the properties of the composite material: High resistance to corrosion and higher specific strength. Depending on the application and at constant load, a GRP bolt can yield a high weight reduction.
The application of glass fiber reinforced plastics (GRP) offers various possibilities.In cooperation with FiReP International AG (Switzerland), Sinorock offers a range of GRP bolts that are manufactured using the latest technologies. The material offers high mechanical solidity and favorable long-term behavior for anchor technology.
Benefits of GRP bolts:
1.Good machinability
2.Corrosion resistance
3.High tensile strength
4.Low weight
5.Easy handling
6.Good ductility
