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.

The SupAnchor Self-Drilling Anchor is a unique anchoring system and is todayÂë answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil. Features and Advantages Fits SupAnchor standard Boomer, ROC and Mustang rigs. Particulary suitable for difficult ground conditions. A high rate of installation since drilling, placing and grouting can be performed in one single operation. Self drilling system eliminates the requirement for a cased borehole. Installation with simultaneous drilling and grouting possible. Easy installation in all directions, also upwards. Suitable for working in limited space, height and in areas of difficult access. Simple post grouting system.

Product description Luhui r32 self drilling hollow anchor bolts is mainly used in underground engineering , like weak surrounding rock, fault fracture zone, highland stress large deformation and other complex geology. Especially in serious hole collapse and deep fault rock situation, ordinary anchor rod is incapable of action. Lhz anchor bolt set drilling, grouting, lengthen and anchoring multifunction all in one, in all kinds of bad surrounding rock engineering applications achieved ideal support effect.

Connect the alloy drill and anchor rod one end, on the other end, connect the drill sleeve and shank adapter , then connect the drilling rig or hand-held drill. Then start drilling, fill the cooling water while drilling.( if you want to lengthen the anchor rod, can connect the coupling, and then drilling) 2. Take down the drill, put the stop-grouting plug into the rod, and insert it to the hole, then ready to grout. Special circumstances like surrounding rock grouting tension is over or surrounding rock is too broken, can use anchor agent to seal the hole. 3. Connect quick grouting coupling and anchor rod end, connect other end of grouting machine. 4. Start grouting, when grouting full and reach design value then power off . Grouting pressure according to the design parameters and grouting machine performance determine , cement/sand reference values is 1:0 ~ 1:1, water/cement reference value is 0.45:1 ~ 0.5:1. 5. Install anchor plate and nuts, and tighten nuts.

Anti-corrosion Mechanism Immerse the derusted anchor bar and accessories in liquid zinc for a certain time, so that the atoms can penetrate and diffuse each other, thereby forming an iron-zinc alloy layer, which is dense, uniform, firmly bonded, bright and corrosion resistant. Zinc is an amphoteric metal. In thermodynamics, zinc has a stable area. Hot-dip galvanizing is an electrochemical anti-corrosion method, which hinder further corrosion through insoluble chemical substances produced by interaction between zinc and concrete solution. Product Standard Sinorock has formulated the standard for galvanized products coatings in accordance with ISO 1461 " Hot dip galvanized coatings on fabricated iron and steel articles Specifications and test methods". The coating thickness of main products is as follows: Featurs and Advantages Excellent anti-corrosion properties: As zinc is an active metal, after coating surface is damaged, it will protect the steel by battery effect. Long service life: Zinc layer is consumed very slowly in the atmosphere, so its service life far exceeds that of any other coatings. Full protection: As immersed into hot-dip galvanizing bath, products are fully protected and anti-corrosion effect is better. Lower price: In most cases, the hot-dip galvanizing cost is lower. Zinc coating is more durable than others, and does not require maintenance in the future. High processing efficiency: Hot-dip galvanizing bath is simple and efficiency is higher than other coatings. Not affect steel performance: Hot-dip galvanizing is carried out in an environment of more than 400 �¢??, and will not affect the performance and toughness of steel. Service Life Generally, the service life of hot-dip galvanized products is more than 50 years in most environments, and it will be different according to corrosion level of the environment. According to ISO 12944-2 "Paints and varnishes- Corrosion protection of steel structures by protective paint systems-Part 2: Environmental classification" (equivalent to GB/T 30790.2), The table below lists the reference rates for different atmospheric-corrosivity environment categories.
