The MEGABolt-GFRP Self Drilling Anchor is used in Mining, Tunneling and Civil Engineering widely.

It provides more possibilities as an alternative to metal. The GFRP Bolt is manufactured with high quality GFRP material (Glass fiber Reinforced Polymer).

The GFRP Bolt have a high tensile load and bearing capacity with accessories, but the weight is only one quarter of metal product.

The GFRP Bolt can be cut freely due to all-threaded profiles at job site.

Description of MEGABolt-GFRP Self Drilling Anchor

The MEGABolt-GFRP Self Drilling Anchor Bolt can realize fast drilling and installation due to its unique function which integrates drilling, grouting and anchoring as a whole. The centre hole allows flushing with water during drilling and the execution of anchor grouting. The 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 length is flexible due to cuttability and connection by couplings.

Applications of MEGABolt-GFRP Self Drilling Anchor

The basic application of MEGABolt GFRP is for use in soil conditions where there is a risk of the drill hole collapsing due to pulling out of drill bit, as in the classical
anchor installation process. The MEGABolt system is suitable for a variety of different rock conditions and our drill bits are available in various diameters. The MEGABolt SDA system can be deployed for various simultaneous drilling and grouting purposes including:
