What is stay cable protection?
Stay cable protection refers to the use of materials and systems designed to shield the cables of cable-stayed bridges from environmental and mechanical damage. This includes protection from corrosion, UV radiation, temperature fluctuations, and physical wear.
How does it work?
Protection methods typically involve the application of external barriers such as HDPE sheathing, double sheathing systems, or specialized protective wraps. These layers act as a shield against moisture, pollutants, and oth...
Your trusted partner for robust stay cables
At DYWIDAG, we know that no two bridges are alike. That’s why our cable protection services combine smart technology with customized execution to strengthen new and ageing stay cables from installation, through to maintenance and ongoing monitoring—ensuring your unique bridge configuration gets exactly what it needs to stand the test of time.
Unlike one-size-fits-all approaches, we start with a detailed site survey to assess structural and environmental conditions. Then, we design a bespoke prote...
Types of protection
Corrosion and UV protection
Steel cables and HDPE pipes degrade over time when exposed to harsh environments. Our high-performance wrapping systems prevent corrosion and UV damage, ideal for both maintenance and strengthening on new or existing bridges
Vibration and fatigue
Constant movement from wind and traffic can lead to long-term fatigue. We offer retrofit dampers, welded helical fillets, and engineered solutions to control vibrations and extend cable lifespan.
Fire Exposure
Stay cables need protection in high-temperature or fire-risk zones. Our fire-resistant wraps and coatings help safeguard structural performance and meet strict fire safety requirements.
Blast and impact
In critical or high-risk areas, stay cables must be ready for more than environmental stress. We provide blast protection systems that increase resilience against impact and intentional attack.
Ultimate protection with Cableskin® by DYWIDAG
DYWIDAG’s Cableskin® technology brings a time-proven pipeline coating method to bridge stay cables. Originally used on large-diameter pipelines since the 1960s, Cableskin® was re-engineered in 2004 for both new and aging stay cables, fusing multilayer butyl-rubber tapes into a single, seamless sheath.
Rather than relying on scaffolding or extensive surface prep, our self-driving CE-certified and semi-automated wrapping robots — alongside small, specialized crews — apply Cableskin® quickly, often ...

HDPE Sheathing for long-term stay cable protection
Beyond Cableskin, DYWIDAG’s HDPE (High-Strength Polyethylene) sheathing provides a durable outer barrier that protects stay cables from UV radiation, moisture, and environmental wear. This outer layer plays a crucial role in preserving the structural integrity of cable-stayed bridges by preventing corrosion and reducing fatigue over the asset’s lifetime.
Repair and Maintenance of PE Sheathing
Over time, exposure to sunlight, temperature cycles, and weathering can cause the sheathing to fade or cra...
Cable fire and blast protection
In critical infrastructure, cable-stayed systems must be designed to withstand not only environmental exposure but also extreme events such as fire and blast. DYWIDAG provides advanced passive protection systems that safeguard structural cables and their anchorage zones against high temperatures and sudden impact loads, preserving the integrity of the structure even under severe conditions.
Our cable fire protection systems are engineered to delay heat transfer to the cable core, maintaining load...
