DYWIDAG Post-Tensioning Systems and Stay Cable Systems are world renowned for reliability and performance; they are perfectly suitable for all applications in post-tensioned construction. They embrace the whole spectrum from bridge construction and buildings to civil applications – both above and below ground. The first ever structure built with a prototype DYWIDAG Post-Tensioning System using Bars was the arch bridge Alsleben (Germany) in 1927. From that time on, DYWIDAG has continuously improved its systems to keep up with the growing demand of modern construction technology. In addition to traditional post-tensioning systems with bars, DSI offers a complete product line in strand posttensioning (bonded, unbonded and external) as well as stay-cable systems to fulfill the changing requirements in the industry today and tomorrow.
Our stay cable systems have always combined the highest safety and reliability standards with excellent economical efficiency in their research and development. Dependable corrosion protection methods, damper design, fire protection, vibration measurements and the recently developed DYNA® Force monitoring system significantly contribute to the longevity of modern construction.
