Self drilling anchor is a kind of hollow anchor bolts, can be used as drill bar and also grouting pipe. Seriflux, going through hollow anchor bar and ejecting from drill bit, fills cracks and drill holes in surrounding stratum, which makes Self drilling anchor integrate with surrounding soil body and then haves reinforcement effect. So Self drilling anchor is a new supporting technology combining functions of drilling, grouting and anchoring together.

Self drilling anchor also has character of lengthening. So short anchor bar can use small drill machine at narrow environment. Without casing pipe, self drilling anchor is suitable for hole collapse stratum to reinforce existing structure. Nowadays, self drilling anchor is widely used in infrastructure projects, such as slope support of hydropower station and railway tunnel support.

Sinorock self drilling rock anchors adopted the advanced manufacturing process and procedures inproduction,ensuring high quality steels and tungsten carbides to guarantee the consistent highquality of the products since being ISO9001 accredited,through our many years of effort,wegradually developed independent development of various designs and manufacture of self drilling rock bolt toosand formed a perfect service & quality control system including tight quality control procedureand a complete after sale service teams.

Our production of self drilling rock anchor 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.The updating of the production processes according to the quality assurance certification ISO 9001:2008, implemented since long time now, guarantees very high standards levels of our products.
