1.GRP drilling anchor 2.Light weight 3.High tensile strength ,anti-corrosion 4.Safety, no sparks out of direct cutting

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

Product 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 Range:

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

ground support
