Product Structure:

Self Drilling Anchor Bolts are a bolting solution for unstable ground conditions such as sand, gravel, sit, and clay, and in soft to medium fractured rock formations. For projects facing such ground conditions, self -drilling anchors should be considered as the main productivity solution. Self-drilling anchor bolt is composed of a hollow anchor bolt, anchor nut, anchor plate, anchor coupler, drill bit and centralizer. By drilling a hole in collapsing soil or loose rock, with an efficient hollow bar and a drill bit, and after the drilling operation injecting grout into the hollow bar and surrounding cavity, self-drilling anchors are a top productivity solution.

Product Application:

Self drilling anchor bolt system is mainly used for tunnel and underground engineering, slope engineering, ground and foundation engineering. It can be used for pre-construction support and can effectively enhance the stability of soil and rock mass.
