FRP threaded rods are made of glass fiber and reinforced resin after curing and heating. It is a kind of bolt with full double thread winding rod. FRP threaded rods are mainly used for the support of coal and rock tunnels, semi-coal rock tunnels, coal walls, slope anchors and other types of underground projects. FRP threaded rods are favored by mine users because of their light weight, easy transportation, high tensile strength, corrosion resistance, flame retardant, antistatic and easy construction.

Features of FRP threaded rods:
1. High strength: The tensile strength is better than ordinary steel, higher than the steel bars of the same specification, and has good fatigue resistance.
2. Good corrosion resistance: it can resist the corrosion of chloride ions and low PH value, especially the corrosion resistance of chlorine compounds that resist carbon compounds, and the long-term support underground is not rusty.
3. Strong plasticity: stable elastic modulus, stable size under thermal stress, bending and other shapes can be arbitrarily thermoformed. Good safety performance, non-conducting, non-conducting, flame-retardant and anti-static. When cutting, no sparks are generated and the picks of the cutting machine are not damaged.
The above is an introduction to the characteristics of FRP threaded rods, I hope it will be helpful to you.
