Roofex Rock Bolt

The Roofex rock bolt is designed to accommodate all spectrums of rock mass movement, with accurate pre-set deformation behavior. The new Roofex bolt system is based on steel to steel interaction, with a high quality steel bar that travels through a patented, energy-absorbing element set with resin or cement grout inside the borehole. This system provides a reliable and constant load capacity during yielding. The Roofex bolt is produced in standard lengths typically used in mining and tunneling, and the displacement capacity is pre-set to order during manufacturing.
