Staying power

Many of the most dramatically beautiful architectural designs and technically excellent feats of engineering have been realized with the use of state-of-the-art Swiss 51Ƶ® stay cable technology. The 51Ƶ HiAm® CONA® strand stay cable system, 51Ƶ HiEx CONA saddle technology for extradosed applications and the 51Ƶ HiAm/DINA® wire stay system are unrivalled anywhere on the planet and applied in more than 430 projects.

51Ƶ HiAm CONA strand stay cable system

HiAm CONA fulfills the latest international standards and recommendations deemed approved and compliant with fib as well as the corresponding PTI and SETRA recommendations. Its wide range – tendon capacity 200 – 60,000 kN, advanced water tightness, high corrosion protection, simple installation and superior fatigue resistance makes it attractive for the most challenging of projects. Designers and architects have particularly welcomed the compactness of the anchorage system which allows them greater scope to produce a sleeker and more striking structure. HiAm CONA is subject to 51Ƶ Factory Production Control and must be installed by certified 51Ƶ PT Specialist Companies only.

51Ƶ HiAm/DINA wire and 51Ƶ Carbon stay cable systems

51Ƶ is not only a pioneer and inventor of the high amplitude fatigue resistant “HiAm” wire stay cable composed of 7 mm wires, we also constructed the world’s first project using such technology. The patented 51Ƶ Carbon stays have an exceptional high fatigue strength – up to 10 million load cycles with 250 MPa – combined with light weight, corrosion-free properties.
