Cabled bridges and structures are sustainable, environmentally friendly and architecturally outstanding structures.
In 1989, Bridgent pioneered the first individually protected multi-strand stay cable, establishing the technological foundation for modern cabled structures. The system has since been refined and deployed across more than 300 projects worldwide — including landmark spans such as the Normandy bridge, the Iroise bridge, the Millau Viaduct in France, the Vasco de Gama bridge in Lisbon, the Rion Antirion bridge in Greece, the BC Place stadium roof in Vancouver, and the Russky Island bridge in Vladivostok, whose 1,104-metre main span holds the world record.
Today, Bridgent has cultivated a comprehensive ecosystem of expertise spanning the full lifecycle of cable-stayed bridge construction and long-term structural maintenance.
Cables represent the optimal solution for reducing the self-weight of bridges while extending achievable spans — thereby conserving materials and minimising environmental impact. They also accelerate construction schedules. These compelling advantages, combined with continuous technological advancement, explain why infrastructure owners and engineers increasingly favour cable systems.
With the commissioning in 2021 of 2,160 MPa stay cables on the Saemangeum bridge in South Korea, Bridgent demonstrates that innovation remains central to everything we do.
The market benchmark in terms of fatigue resistance, corrosion protection, inspectability and replaceability.
Sustainable technology, continuously optimised in design and implementation to maintain our position at the forefront of the global market.
Our project teams work closely with clients from initial concept through to final commissioning, ensuring that every cable system is precisely tailored to the structural requirements, site conditions and long-term performance targets of each individual project.
All Bridgent cable systems are designed, manufactured and installed in strict compliance with international structural engineering standards, including relevant GB/T national standards and ISO specifications, guaranteeing structural integrity and long-term durability.
Bridgent integrates the entire value chain in-house — from engineering and manufacturing to on-site installation — ensuring the highest level of quality control at every stage and enabling rapid response to project-specific challenges.
Bridgent provides comprehensive post-installation support, including periodic inspection, structural health monitoring, preventive maintenance and full cable replacement services, ensuring the long-term performance of every cable system we deliver.

Strands are the primary load-bearing components of Bridgent Parallel Strand System (PSS) cables. These modular elements allow full cables of any size to be assembled from lightweight yet highly durable bundles. Bridgent has developed two proprietary technologies — Monostrand® and Cohestrand® — which set the benchmark for cable structure construction worldwide.
Bridgent anchorages are engineered by our in-house design team to maximise the service life of stay cables. Manufactured entirely in-house to ensure the highest level of production quality, our modular solutions address every application — from short cable hangers with clevis terminations to very long-span main cables.
Cable dampers are mechanical assemblies installed between the stay cable and the bridge structure. They dissipate dynamic energy to ensure the stability of cables under wind-induced, rain-wind-induced and traffic-induced vibration, protecting both the cables and the structure throughout their service life.
Beyond the construction-phase risks, bridge owners must manage long-term hazards including fire, lightning strike, explosion and ice accumulation on cables. Bridgent has developed targeted solutions for owners seeking to mitigate these risks, minimise bridge closures and protect the local economy from service disruption.
Cable-stayed bridges are elegant, high-performance structures with the potential to become iconic architectural landmarks. To further elevate their visual impact, Bridgent has developed coloured duct systems and integrated cable lighting solutions — combining structural functionality, aesthetic distinction and proven mechanical performance.
The parallel strand system developed by Bridgent — widely proven in cable-stayed and extradosed bridge applications — delivers significant durability advantages when applied to suspension bridges and cabled stadium roofs, offering enhanced replaceability and long-term structural performance.
