R thread self drilling hollow bar anchor is composed by hollow anchor bolt, anchor nut, anchor plate, anchor coupler, drill bit, centralizer, and the hollow anchor bars can be cut and lengthened by coupling on request. Functions: R thread self drilling hollow bar anchor is an advanced system which can ensure the anchoring effect for complex ground conditions. It can be integrated with the functions of drilling, grouting and anchoring. Conditions: Tunneling Mining Slope Stabilization Foundation Support Features and advantages: 1. Safe, reliable, and time saving. 2. Simple installation & operation. 3. Choice of drill bits for different ground conditions. 4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively. 5. Anchor bars can be cut and lengthened on request, applying to narrow spaces. 6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.

Stainless steel self drilling anchor bolt is made of stainless steel materials. It is an alloy steel self drilling anchor bolt which can resist corrosion in air or chemical corrosion conditions. Functions: Owning to its good welding performance & inoxidizability, stainless steel rock 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 sub-sea tunnel, seaport, seawall and some projects in the industrial pollution area. Conditions: It applied to marine environment and chloride corrosion. It is also used to chemical industry and infrastructures of important equipment which requires high anti-corrosion quality. It widely used in bay, pier, pile foundation, breakwater and mooring system. Features and advantages: 1. Good anti-corrosion quality and antioxidant activity. 2. High temperature oxidation resistance, resisting fire at a certain extent. 3. Stainless steel has good strength and high wear resistance. 4. Its anti-corrosion and resistance to chloride is prior to other coating re-bars due to its repairing oxide layer. Cases: Stainless steel self-drilling anchor bolt system is mainly used for tunnel and underground engineering, slope engineering, ground and foundation engineering. It can be used for pre-construction support and can effectively enhance the stability of soil and rock mass.
