Product Description
Customized Color FRP Rock Bolt with Threaded Rod
Traditional steel rockbolt system is widely applied in coal mine supporting construction design, this system mostly applied as temporary support mesure.
All-thread Glass Fiber Reinforcement Polymer( GFRP Rockbolt)series product notonly open the possibility of new design, but also provide a very beneficial substitution for traditional engineer steel rockbolt system.

Product Feature
(1) The glass fiber reinforced rock bolt is light weight with high strength: the relative weight is only 1.5-2.0, and the strength can be close to the level of the steel, and the supporting strength of the FRP bolt is close to that of the steel material, and its weight is only about 1/5 of the same size.
(2) Glass fiber reinforced plastic rock bolt is easy to cut, it won't produce sparks, glass steel is not a metal material, easy to cut, and will not produce sparks, especially suitable for "fully mechanized". It can not only ensure the safety of underground coal mine, but also solve the mine anchor supporting function, and it can greatly improve the efficiency of coal mining, reduce the cut coal machine cut tooth damage to reduce the production cost.
Application
Fiberglass rock bolt has been used in construction industry, automotive and railway transportation industry, electrical industry and communication engineering.
