ARES produces and develops Rock Bolts bars since
1982.
Therefore has the ability to find the best
solution to meet customer’s requirements.
Due to special mechanical characteristics (i.e.
very high elongation, very high ductility) Rock
Bolts are essentially used in mining
applications.
Other geotechnical applications for Rock Bolts
are stabilization of soil masses under load,
cavern/ tunnel walls, excavations or slopes.
Other advantages are high loads which can be
carried with small borehole diameters and high
shear bonding between deformed bar and cement
grout. |
