mining underground tunnel fiberglass rock bolt :
Product Introduction :
Feature
Rod density 1.6 - 2.1g / m³
high specific strength , tensile strength higher than 20% of the steel bars of the same specifications
light weight , convenient work surface artificial transportation
corrosion
flame retardant , antistatic
easy to cut and will not produce sparks
bond strength and anchorage strong reinforcement
Advantages:
1.Light weight,it is only 1/4 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 emmiting the electromagnetic wave
4.Can meet the requiement of the permanent supporting
5.High strenth:it is screw thread and anchored force strength
6.For the supporting requirements,it can be adjusted the length
7.Strong affinity for the concrete and capsule resin
