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.
