The Rebar
Advantage:
The core highlights of the LH anchors are the Thickest Rebar technology, which ensures ultra-high strength and durability for extreme loading environments, and the integration of Tiscon 500 high-standard material, which provides excellent seismic performance and corrosion resistance to extend the life of the project. In addition, the innovative introduction of the Titanium Rebar element significantly reduces weight and improves toughness, combining ease of construction with structural safety. The combination of the three makes this product the preferred solution for tunneling and slope support, with comprehensive performance far exceeding that of traditional anchors, providing customers with a reliable and cost-effective solution.
Product Description:
Left-handed anchor is a high-performance support product, adopting High Strength Rebar as the core material, with excellent tensile, shear and deformation resistance, suitable for reinforcement projects under complex geological conditions such as tunnels, foundation pits and slopes. Its unique threaded design enhances the occlusion with the geotechnical body and ensures the stability of the anchoring system.
As an industry-leading solution, The Rebar undergoes a special heat treatment process to further enhance its yield strength and fatigue life, maintaining excellent performance even under long-term dynamic loading. In addition, the product's innovative incorporation of Titanium Rebar technology not only reduces overall weight, but also significantly improves corrosion resistance and toughness, making it particularly suitable for long-term use in high humidity, salt or acidic environments.
With its comprehensive advantages of high load bearing, light weight and corrosion resistance, the left-handed anchor becomes an ideal choice for modern geotechnical engineering and underground structure reinforcement, which is easy to construct, safe and reliable, and can significantly extend the project life and reduce maintenance costs.

Product Description:
Left-handed anchor rods, for roadway support, are characterized by high strength, reasonable structure and large preload force. Left-handed anchor can increase the binding force on the surrounding rock, and the installation is mechanized, which is easier and faster. Lefty anchors can be end anchors, extension anchors and full anchors. According to the steel grade, the left-hand anchor is classified as MG335/MG500/MG600, and the diameter of the rod body is from 16mm to 22mm, which can also be processed according to the construction requirements. Left-handed resin anchor rods have high strength, reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can be mechanized for rapid installation. It can be used as end anchor, extension anchor and full anchor, mainly used for high strength support of large deformation roadway in highland pressure mines, and also can be used for high strength roadway support of various projects such as railroads, hydropower and so on.
The development history of rebar anchors:
In recent years, China's left-handed anchor industry has adopted a two-legged approach. On the one hand, increase the strength of independent research and development, increase scientific research investment. On the other hand, the left-handed anchor enterprises to go out through overseas mergers and acquisitions in overseas acquisition of technology, equipment and markets.
Usage:
Mining anchor is a kind of anchor rod commonly used in coal mine underground support and traditional metal anchor compared to its quality and solid full length and other strong length can be intercepted according to the specific needs of the rod body is easy to cut the operation is simple and convenient so that you do not make difficult to use so that the roadway and other construction sites are very favorable to the safety and construction.
Use method.
1. Determine the anchor hole position according to the design requirements, and drill the hole with drilling equipment.
2.Blow out the rock dust in the hole with pressurized air.
3. Send the anchoring agent to the bottom of the hole, hold it against the anchor and start mixing (mixing time is specified according to the type of anchoring agent), after mixing, unload the mixing tool, and after the waiting time is reached, unload the mixing connecting head, put on the anchor plate, ball washer, friction washer, and tighten the nut with a wrench.
