The Sinorock self drilling anchor bolt is a unique anchoring system and is today's answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production.The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

The “self drilling anchor bolt” is the most common used system for rock mass stabilization, especially in tunneling and mining industry.Thanks to our long experience in the steel heat treatment,we manufacture and
distribute high resistance continuos thread hollow bars, offering the following advantages:
1.They can be used as self drilling bolts with a disposable bit;
2.They can support an overhead anchor device;
3.They can provide a continuos closed circuit for high pressure grout injection for pumping thixotropic grout mixtures;
4.they can be cut and coupled on site to get all lengths;
5.lower weight,lower handling costs and easier setting operations;

We are authorized self drilling anchor bolt manufacturer for construction,We take up job for rebar fixing applications and rod fixing for structural connections for wet and submerged condition also.Sinorock offers a variety of services to meet your construction needs, from earth retention and rockfall protection systems to engineering services.
