1.The density of frp rock bolt is between 1.6 and 2.1 g/cm3 .
2.The tensile strength of frp rock bolt is higher than normal rebar with the same dimension by 20%.
3.The weight is light,so the rock bolts can be transported easily.
4.Frp rock bolt is corrosion-resistant,fire-retardant and antistatic.
5.Our frp rock bolt are made of plastic materials, so they're easy to cut without sparkle.
6.Its swell factor is close to that of concrete and its bond stress and anchorage force is stronger than normal rebar.
Range of application
1.Applicable to slope protection supporting in mine, traffic, municipal works, water and hydropower projects and military defense.
2.Applicable to coal mine rock lane and half coal rock lane of comprehensive mechanized coal mining face of mine.
