Product Details

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.Strong affinity for the concrete and capsule resin 4.Can meet the requirement of the permanent supporting

4.High strength: it is screw thread and anchored force strength

5.For the supporting requirements, it can be adjusted the length

6.Anti-erosion,it can strongly adapt to the environment,and no emmiting the electromagnetic wave

GFRP Rockbolt has widely used in tunnel supporting of coal mine, and provide a very beneficial substitution for traditional steel rockbolt system.
