The split set is a new type of anchor bolt that provides full-length anchorage and actively reinforces the surrounding rock. It is made by high-strength steel plate with longitudinal slits. When installed in a borehole slightly smaller than its diameter, it can immediately apply radial pressure to the hole wall and resist the sliding of the surrounding rock with frictional force throughout its entire length. Coupled with the supporting force of the anchor plate, the surrounding rock is subjected to three-directional stress and achieves rock layer stability.

In cases such as blasting vibration, rock anchoring movement etc., the post-installed anchoring force significantly increases. When the surrounding rock undergoes significant displacement, the split set does not lose its supporting resistance.The split set is easy to install and has a low cost. Once installed, it immediately takes effect and has the advantages of immediate support, efficient installation and adaptability to large deformations. It is widely used in metal mine mining.

Our galvanized split set with over 80 μm galvanized layer thickness, they are suitable for various environments exposed to acid and alkali corrosion, as well as situations where the strata and groundwater contain sulfides and chlorides, or where they are subject to seawater erosion. The service life exceeds 50 years.
