Built on advanced technology and decades of know-how, we deliver special-construction solutions that push past the limits of civil engineering.
Rock Cut-slope
Permanent 2,360MPa strand anchors installed on rock cut faces to prevent collapse.
Cut & Fill Slope
Permanent anchors combined with SAP/shield walls and PC/FDS blocks to prevent failure.
Debris-flow System
O-Net, Q-Net, T-Dex and integrated reinforcement defend against landslide debris flow.
Tie Cable
Distributes heavy loads on harbor moorings, dam cofferdams and temporary roads.
Bridge Cable
High-strength strand for cable-stayed and suspension bridges, extending span.
Rockfall System
Rockfall nets and fences that block damage from falling rock.
Integrated Slope
Rock bolts and nailing combined with nets to stop progressive slope failure.
2,360MPa strand,
engineered to share the load.
Permanent-anchor technology using high-strength strand stabilizes rock and cut/fill slopes. A compression-composite anchorage removes concentrated load and sustains long-term tension.
