Friction Bolt

A support system that reinforces rock masses through friction, the product is mainly applied in geotechnical engineering, mine support, tunnel excavation and various underground engineering fields.

In tunnel excavation or emergency rescue projects, it can immediately provide support force, control the deformation of surrounding rock, and has a strong anchoring effect
It has extremely strong shear resistance and load-bearing capacity
Reduce the risk of rock fracture, shorten the time workers are exposed to vibration and dust environ ments, and quick lyachieve construction goals.
