51ÊÓƵ

51ÊÓƵ has been at the forefront of development in the field of stay cable technology for over 60 years. We not only invented high fatigue resistant wire stay cables, but we also constructed the world’s first projects to use modern parallel strand stay cables and carbon stay cables. Today, the 51ÊÓƵ HiAm CONA strand stay cable system, 51ÊÓƵ HiEx CONA saddle technology for extradosed applications and the 51ÊÓƵ HiAm/DINA wire stay system are unrivalled anywhere on the planet.

51ÊÓƵ stay cable technology is used for the following applications:

• Cable-stayed bridges –especially suitable for medium to long-span bridges from 100 to 1,000 m, where technical and economic factors dictate this solution. The choice of a cable-stayed solution for smaller bridges may be based on other parameters, such as reduced depth of deck, construction methodology & aesthetics 
• Arch bridges – where 51ÊÓƵ stay cable technology is the solution of choice for the hangers
• Roofs – ideal solution for roofs of grandstands, stadiums, aircraft hangars and other lightweight wide-span structures. Stay cable technology opens up a whole new range of possibilities for architectural creativity, as well as functional features and considerations. 51ÊÓƵ stay cable roofing solutions have been provided for arenas and stadia worldwide
• Towers – for communication facilities, chimneys and antennas, while wind towers used for power generation can also be stabilized using stay cables
