Weathering of soft rocks is usually considered as an important factor in various fields such as geology, engineering geology, mineralogy, soil and rock mechanics, and geomorphology. The problem of stability over time should be considered for slopes excavated in soft rocks, in case they are not protected against weathering processes. In addition to disintegration of material on slope surface, the weathering also results in shear strength reduction in the interior of the slope. 

Rock bolting is utilized to secure potentially unstable sections of the rock mass, improving long term rock stability.Self drilling hollow rock bolts are extensively used on all types of projects, from standard buildings to dams and nuclear power plants. 

They can also be used to firmly affix embed plates to a concrete foundation when used with a structural steel element. 

To accomplish complex drilling tasks like tunneling,grouting or slope stablization,Self drilling hollow rock bolt is utilized for efficient performance.Our production of rock bolt has increased progressively to cover the national markets due to the competitiveness level reached by our company after both the metal treatment technology innovation and the experience made in the field during these past years.
