Fighting fire
A developing market
Safety concerns are constantly changing. Traffic flows have become more and more dense in urban areas with growing populations, and the risk linked to the transport of dangerous goods hence grows. At the same time, bridges with very long spans are increasingly commonplace. During the past ten years, these factors have increased the demand for systems offering fire protection for cable-supported engineering structures.
Recognised expertise
Being a pioneer in this market, VSL has developed a patented fire protection system applied on multiple projects in Europe, the United States and Asia. The company offers solutions that have undergone the most stringent qualification tests and which can be implemented to protect stay cable systems as well as post-tensioning cables.
The patented VSL Fire Protection system has been designed and certified for use on stay cables. Its performance was tested under various hydrocarbon fire scenarios with strict qualification criteria.
How does it work?
The VSL Fire Protection system uses a combination of materials suited for exposure to high-temperature fires; this combination was developed to be fully integrated with the cable envelope to fully maintain the cables’ characteristics in functionality, robustness and durability.
