As a new kind of anchor bolt, friction rock bolt is considered to be the simplest supporting bolt in metal mining and tunneling projects. The unique shape provides large contact area between rock and steel tube which can offer strong friction between friction bolt and rock, high shearing strength and tensile strength.

Friction rock bolt-only because of its construction, a high friction with the rock in which the bolt is installed without the need of additional bonding materials. This friction, measured in kN. pull out strength, ensures immediately ground support after installation. The friction is the result of the spring action of the special V-profile of the Sinorock friction bolt that is pressed into in a pre drilled hole with a smaller diameter than the ordinary rock bolt.

And Sinorock is  guaranteed in friction rock bolt manufacturing field.Sinorock is a company with the accent on quality, safety and service.

To choose the right product for the job, we visit the customer with samples and advise the tooling and installation methods. Pull out tests can be made to confirm the bolt choice and installation techniques.

We keep a certain stock of rock bolts for a flexible supply in case of urgencies. The modern production techniques ensure fast delivery of small and large amount of rock bolts.
