FRP Bolt
TheFRP bolt(fiber-glass reinforced plastics bolt) made from the glass fiber and special resin, with the properties of light, anti-corrosion, cutting easily
Usage & Application :
Bolt supporting in seam roadway of coal mine; project of hydraulics and electric power; tunnel project;
slope protection; chemical anticorrosion structural member etc.
Advantages:
1) Light weight, it is only one-fourth the weight of steel with the same size;
2) Tensile strength (ability to resist stretching), it surpasses ordinary steel;
3) Anti-erosion, it can strongly adapt to the environment, and no emitting the electromagnetic wave;
4) Can be met the requirement of the permanent support;
5) Can be cut easily into any dimensions without any sparks;
6) High strength: it is screw thread and anchored force strength;
7) For the supporting requirements, it can be adjusted the length,;
8) Strong affinity for concrete and capsule resin.
