FRP Bolt

Rod body length, pallet material and size according to user requirements processing production

FRP Bolt is to use glass fiber reinforced resin, the pultrusion winding composite and forming surface rough type or full thread rod body, match with tray, nut and other components of the bolt. Mainly used in coal mine rock, half coal rock, coal wall, wall rock surface, slope anchorage and other types of underground engineering support.

Product features

1.   FRP anchor rod body density 1.6 ~ 2.1 g/cm3

2.   Tensile strength high

3.   Light dead weight, convenient transportation

4.   Corrosion resistance

5.   Flame retardant, antistatic

6.   The product of plastic material, easy cutting and won't produce spark

7.   Expansion coefficient and concrete close, and the grip of the anchoring force is stronger than metal reinforcement material

 Scope

1.   Used in mining, transportation, municipal, water conservancy and hydropower, military and civil air defence underground engineering slope protection support

2. Suitable for fully mechanized working face of coal mine roadway and half coal rock support
