Self Drilling Fiberglass Anchor Bolts 38mm GFRP Suppliers In Tunneling
Features
The SupFRP® GFRP SDA Bolt can be used in soft rock or clay soil, for the reinforcement of the face of the tunnel or for slope stabilization. Furthermore the cuttability protects the machinery by avoiding obstructions while drifting or enlarging tunnels.The fully threaded resin anchor rod glass fiber reinforced rod is formed by heating and curing of glass fiber yarn, resin, and curing agent. The shape of the anchor rod body is full thread, and its characteristics are as follows:
Light pole body: The weight of GFRP bolt is only one-fourth of the weight of the
steel bolt of the same specification, which is easy to install and
construct, reduce labor intensity, and save transportation costs.
Strong corrosion resistance: GFRP anchor bolt is made of unsaturated polyester resin
and glass fiber. It is resistant to rust, strong in acid and alkali
environments, does not reflect electromagnetic waves, and can meet
the needs of long-term support.
Easy to operate: it is easy to cut, does not produce sparks when cutting, has a
certain protective effect on the shearer, is convenient for
comprehensive mining operations, is beneficial to production
safety, and improves production efficiency;
High strength: rod tensile strength ≥300MPa, torque ≥40N·m, shear strength
≥75Mpa.
