What Are Stay Cable Systems?
Stay cable systems consist of prestressing strands connecting pylons or main cables to the deck in cable-stayed and suspension bridges. As the primary load-carrying elements in long-span bridges, these systems require high strength, corrosion protection and long service life.
ASZ Grup supplies high-strength strands, HDPE-sheathed cable systems, anchorage solutions and vibration damping accessories for stay cable projects. Our bridge and viaduct references include cable-stayed bridge applications.

Frequently Asked Questions
What is the difference between stay cable and post-tensioning?
Post-tensioning applies prestress to reinforced concrete members. Stay cables are external suspension elements connecting bridge pylons to the deck or main cable. Both rely on prestressing principles but serve different structural roles.
What is the service life of stay cables?
With correct design, corrosion protection and periodic maintenance, stay cable systems can deliver 50 years or more of service life.
