Sinorock self drilling anchor products are all manufactured according to strict ISO rules. There are two important quality parameters for a Sinorock self-drilling anchor system.Firstly, that rods can withstand the stipulated breaking load and, secondly,that couplings and bits can be easily threaded. Ultimate load tests are carried out on all load bearing components in accordance with the strict quality process regulations. Should a system fall short of the given tolerances, production is stopped and the fault is rectified.

Self drilling rock bolt has played a crucial role in high slope of hydroelectric station. It has obvious features, such as single rock bolt has big tensile pulling force, great depth and small project amount, it is suitable for different geological conditions. Adopting self drilling rock bolt to construct project can control or reduce the occurrence of rock burst, enhance ability of anti-seismic and control deformation effectively.

To accomplish complex drilling tasks like tunneling,grouting or slope stablization,Self drilling 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.
