SAS rods for tunneling and mining

Anchoring systems are used in various ways in mining and tunnel construction and are used for temporary rehabilitation and protection of the sides or ceiling of the tunnel during its construction, and are also used in mining. Depending on the construction system used, the geology of the surrounding rocks and the hydrological conditions underground, we offer various anchoring systems that meet the specific requirements of the project.

SAS tunneling and mining anchoring systems are available as threaded rods in grades SAS 450/700, SAS 500/550 (with DIBT approval), SAS 650/800, SAS 670/800 and as smooth rods in grades E 360/690-830 . A wide range of steel of different quality ensures technically and economically optimized construction systems.

In addition to the above in this area, we can provide different types of SN anchors from standard reinforcing bars and SDA (self-drilling) anchors for tunnel construction from our production.

The SDA anchor consists of three main components: the head, the steel rod – including the coupling and the disposable drill bit – and the injection body. The steel bar is hollow with a cold-rolled thread and therefore can be cut or joined at any desired point. We can offer SDA anchors from R32 mm – 210 kN to R51 mm – 800 kN maximum load.

We can offer SN anchors made of reinforcing bars in different diameters and qualities of steel B500B, B670/800. For more details, please visit:
