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 difficult geological conditions. Its weakness is the "uncertainty of lifespan" of the thin-walled steel pipe that is fixed in direct contact with the geological formation. 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 products ■ No peeling of the coating layer due to expansion during construction ■ Exhibits excellent corrosion resistance under geological conditions with a pH of 4 to 12, maintaining reinforcement effects over the long term ■ Applies a new material with excellent elongation properties, excelling in deformation characteristics *For more details, please refer to the PDF document or feel free to contact us.
