The self drilling anchor supporting structure must have a good ductility,in other words,no doubt the destruction is inevitable occurs if the self drilling anchor supporting system that has no the pressure and yield properties.The self drilling anchor can be lengthened as required so it is well applicable to railway,tunneling,mining,hyrdroelectric station,slope stabilization,dam,brige foundation,river,breakwater,high-rise construction frastructures and othe projects .And it is more suitable for settlement,collapsed hole,fissures,landslide and so on.Meanwhile,it’s also very convenient for operating in narrow space or with limitedheadrooms and the quality of anchorage material is incomparable.

Sinorock supplies quality self drilling anchor syetem which are made by her manafacture base in China,who is a certified factory according to ISO9001:2008 to our global clents with a competive price. Products are also with CE certification.We operate a business management system aiming to ensure that as a minimum, products and service quality meet this international standard.
The self-drilling anchor system may be used for any soil or rock anchor application within the specified loading limits. They are particularly well-suited for site conditions involving unstable or raveling soils where conventional anchor installation would require drill casing to mantain an open hole between drilling and anchor installation.
Stainless self drilling anchor bolt has good anti-corrosion quality and antioxidant activity which can resist corrosion in air or chemical corrosion conditions.Owning to its good welding performance & inoxidizability, stainless self drilling anchor bolt are mainly used in the permanent support of large initial stress of surrounding rock,or other projects which have special requirement for corrosion resistance, such as bay, pier, pile foundation, breakwater and some projects in the industrial pollution area.
Duplex coating anchor bolt has both hot-dip galvanizing and epoxy coating on the bolt surface. On one hand, the hot-hip
galvanizing coating has dense combination, high anti-corrosion and good toughness. On the other hand, the epoxy coating has excellent physical properties and chemical stability. Anti-corrosion of the combination of two methods determine that the duplex coating rock bolt can keep more than 100 years.
