A new series that improves durability and breaking strength. Required for rock reinforcement where a specified cross-section must be maintained.
This product is suitable for conditions that require higher elasticity (when the rock bolt needs to function within the elastic range and reduce deformation in the excavation area more effectively). With the improvement of yield strength and fracture strength, the excellent features of "Suerex" can now be utilized under greater load conditions. The combination of material technology and Suerex bolt functionality enables reliable installation, support functions that are effective across the entire length of the bolt immediately after installation, and the ability to respond to harsh excavation conditions. 【Features】 ■ Quality can be verified with each installation ■ Safe and simple installation work ■ Provides support capacity as per specifications immediately after installation ■ Does not require harmful chemical products ■ Corrosion resistance suitable for long-term support ■ Not affected by vibrations from blasting ■ Reduction of working time is possible *For more details, please refer to the PDF materials or feel free to contact us.
The entire length is rolled with R32 rope screws to ensure slime discharge performance and stable adhesion performance!
The "IBO Lock Bolt" is a hollow lock bolt with R32 threads rolled along its entire length, making it very easy to handle on-site. It is effective not only as a self-drilling bolt but also as an injection bolt utilizing its hollow structure. It can be applied to a wide range of uses, including pattern bolts, fore-poling, tunnel repairs, LW urethane, and slope reinforcement. 【Features】 ■ R32 rope threads rolled along the entire length ■ Ensures slime discharge performance and stable adhesion performance ■ Allows simultaneous drilling and bolt insertion operations, reducing cycle time ■ Pursues cost-effectiveness through bit selection according to the target geological conditions ■ Applicable to a wide range of uses *For more details, please refer to the PDF document or feel free to contact us.

Instantly anchored in the ground! Introducing rock bolts that eliminate the "uncertainty of life"!
The steel pipe expansion-type friction lock bolt has been adopted as a solution for tunnel construction projects under challenging ground conditions. Its weakness is the "uncertainty of lifespan" of the thin-walled steel pipe that is anchored in direct contact with the ground. This product addresses that weakness. The introduction of the steel pipe expansion-type friction lock bolt, which is expected to have a semi-permanent function. 【Features】 ■ Higher hardness and less prone to scratches compared to other galvanized coatings ■ No peeling of the coating layer due to expansion during construction ■ Exhibits excellent corrosion resistance under ground conditions with a pH of 4 to 12, maintaining reinforcement effects over the long term ■ Utilizes a new material with excellent elongation properties, exhibiting superior deformation characteristics *For more details, please refer to the PDF document or feel free to contact us.
Easily inject and fill grouts of various viscosities! Long-term stable support that can be done manually or automated.
The "CT Bolt" is a combined type rock bolt that is temporarily installed and later permanently secured with grout. It allows for quick and easy installation, and various viscosities of grout can be easily injected and filled, while the polyethylene sleeve protects the bolt from corrosion. Manual installation is possible, and automated installation using a specially developed rock bolt setter is also feasible. 【Features】 ■ Combined type rock bolt ■ Quick and easy installation ■ Easy injection and filling of various viscosities of grout ■ Special hemispherical dome head ■ Unique anti-corrosion structure *For more details, please refer to the PDF document or feel free to contact us.
Introducing the RPE-G (NETIS registered) "multi-functional" friction-type steel pipe expansion lock bolt!
"Multi-functional" Friction Type Steel Pipe Expansion Lock Bolt ◎ Function (1) Water Drainage ■ After the expansion of the RPE lock bolt, applying further water pressure releases the end cap, allowing it to be reused as a hollow water drainage bolt. ■ The drainage hose processes the water flowing from the bolt hole as clean water. ◎ Function (2) Injection from the Tip ■ After the release of the end cap, it becomes a hollow bolt, enabling water-stopping injections, etc. (※ After the release of the end cap, it is possible to inject cement-based or resin-based materials using the hollow space.) ■ The water reduction effect from the water-stopping of the bolt hole can reduce the impact on water shortages caused by tunnel excavation. ※ For more details, please refer to the PDF document or feel free to contact us.
