Self drilling hollow anchor bolt is a widely used anchoring method

Self drilling hollow anchor bolt is extensively applied in structure of foundation pit support, which mainly make use of anchor-hold in the layer of soil in order to maintain the stability of structure. While based on complex geological conditions, the security and supporting effect are more important, so the self drilling hollow anchor bar is quite necessary. Currently, anchor bolt support technology has been applied to many projects, but the project has a certain complexity and uncertainty, every concrete construction of geotechnical engineering, has its own particularity. 

Sinorock self drilling hollow anchor bolt has historically been accepted as a widely used self-drilling anchoring method due to the hollow fully threaded bar can be used as both the drill tooling and the grouted anchor rod, thus installation is operated in a single procedure. We are committed to drive our sustainable development as part of our offering, our research, development and our attractiveness as an employer.
