It is mainly used as a slope protection supporting of coal mine rock lane, side slope anchorage and other underground works
fiberglass reinforced plastics (FRP) rock bolt consists of a rough surface or full thread rod formed by pultrusion or winding with fibre glass and reinforced resin, matching with pallet, nut and other components. It is mainly used as a slope protection supporting of coal mine rock lane, half coal rock lane, coal wall, wall rock, side slope anchorage and other underground works
Product characteristics
FRP rock bolt density: 1.6~2.1g/ cm3;
High tensile strength;
Light deadweight, easy for transportation;
Corrosion-resistant;
Fire retardant, antistatic;
The products are made of plastic materials, easy to cut, without sparkle;
Its swell factor is close to that of concrete; bond stress and anchorage force is stronger than metal reinforced materials
Range of application
Applicable to slope protection supporting in mine, traffic, municipal works, water and hydropower projects and military defense
Applicable to coal mine rock lane and half coal rock lane of comprehensive mechanized coal mining face of mine
