The self drilling rock anchor is a system of Metis rock bolts
The self drilling rock anchor is a system of Metis rock bolts with advanced strength and head load capacity. It was produced for rock support project in mining and tunneling as well as for slope and face stabilization. Owing to continuous coarse thread form the bolts can be compressed if needed.
The products have a high loading capacity and due to their performance they provide a maximum bonding stress with all grouting material.
The cutting ability protects machinery and equipment and prevents damage to machinery while in the installation.
The bolts have a high corrosion-prevention ability under acid conditions and are well applicable for permanent support. The improved flexibility of long tendons is well suited for application without couplings in confined locations. Due to its high tensile strength the bolt has a high and immediate load bearing capacity if applied with fast setting resin capsules. The low weight facilitates handling.
