This product is a new type of MDX combi split set with helical bar inside. The installation is simple and fast. Just drive the MDX split set into the borehole. By rotating the hexagonal nut, the expansion structure at the other end of the MG500 helical bar rotates and expands, firmly anchoring the split set and helical bar to the inner wall of the borehole, which greatly enhances the anchoring force.Internal helical bar can effectively enhance the strength of MDX split set, fundamentally addressing the shortcomings of low anchoring force, limited tensile force, so as to achieve high stress and high load-bearing requirements, and long-term support.

It has a wide range of applications, excellent control over surrounding rock displacement and seismic performance. It can apply pre-compressive stress to the surrounding rock and achieve a large anchoring force in a very short time.

The support effect of MDX split set treated with hot-dip galvanizing can last up to 50 years.
