GRP(FRP) anchor bolt

1.GRP anchor bolt 2.Ideal for use In soft rock, loose and disturbed rock formations 3.High Tensile Strength,light weight

      Fiberglass  reinforced anchor  is made of fiberglass as reinforced material and polyester resin by pultrusion process.

High Torsional strength Suitable for rotary drilling, ideal for use In soft rock, loose and disturbed rock formations.

Technical Features:

1. All thread FRP bolt

2. Safety, no sparks out of direct cutting

3. Light weight, only 1/4 weight of the steel ones of the same specification

4. High tensile strength, each part has the same tensile strength. It can meet the requirement of the super-high strength   

5. Anti-corrosion and anti-ageing, used for permanent support

6. Strong anchoring strength, the strength is equal to the bar itself

7. No reflection to electromagnetic wave, good for concealing of the work

Application Field:

Hard rock mining, Ground stabilization,Salt mines, Tunneling, Tiebacks, Temporary ground support ,Permanent 

ground support
