Sinorock self-drilling anchors provide a unique bolting solution for unstable ground conditions such as sand, gravel, silt, clay and soft to medium fractured rock formations. For projects with such ground conditions,Sinorock self-drilling anchors are the most productive reinforcement solution. The rock anchor features a hollow bore for flushing or for simultaneous drilling and grouting. The rod has a left-hand rope thread for connection to standard drill tooling. It is manufactured from API standard heavy wall steel tubing, cold rolled to form a standard ISO rope thread profile. The rolling process refines the grain structure of the steel, increasing the yield strength to produce a durable drill rod suitable for a range of applications.

Safety in a mine is not something Sinorock,takes lightly. It’s a major issue for those who own and those who work there. A minor fault in a reinforcement bolt may prove fatal. That’s why Sinorock rock bolts are rigorously tested to ensure the best possible quality and reliability. In fact our Quality assurance system is the most comprehensive on the rock reinforcement market today.
