FRP Hollow Rock Bolt is a rock-bolting system based on fully threaded hollow GFRP bars.
It is especially designed for the following applications :
Face-bolting and temporary applications : Cut-ability of FRP makes it the ideal solutions for face bolting or any other tunneling/mining application where further excavation is required.
Installation with grout. The hollow GFRP anchor rod also acts as a grouting pipe to ease installation.
