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