Our TUF-BAR Fiberglass Rock Bolts utilizes our #7 60GPa Fiberglass Rebar which is our strongest load bearing GFRP fiberglass rebar. Its ideal applications include Hard Rock Mining, Ground Stabilization, Salt Mines, Tunneling, and Tibacks. They are used in both permanent and temporary ground support applications. Patents held related to this product include molded left or right handed treads and a composite nut capable of holding over 30,000 pounds of stress. Our TUF-BAR Fiberglass Rock Bolts are non-corrosive, non-magnetic, and non-conductive which guarantees that your project will not weaken due to rust. It is the perfect product for medical and rail applications. In addition, TUF-BAR Fiberglass Rock Bolts are one quarter the weight of steel rock bolts or soil nails. It will save you money in transportation and labor costs.
