FRP bolt is a kind of bolt which mainly consists of unsaturated resin as the basic materials and fiberglass ascomposite material
As we all know, bolts are the fundamental parts of the contemporary coal mine tunnel support, they make the surrounding rock of the tunnel bound together and also make surrounding rock support themselves. So the FRP bolt have the same functions and have more advantages than the common bolts.
Light weight( 1/4 of the same reinforcement weight)
High tensile strength (approximately twice the load of the same reinforcement)
Anti-corrosion and durability
Anti-static
Non-conductive, will not produce sparks when cutting, especially for high gas region
Non-combustible(high thermal insulation)
Easy cutting ( avoid damage the cutting head and available)
Non-magnetic Easy to install and easy to maintain
