Rope护栏is a major representative form of flexible guardrails. It consists of a structure fixed to posts with several cables that are tensioned initially. It primarily relies on the tensile stress of the cables to resist vehicle collisions and absorb impact energy. The cables work within their elastic range during collisions, allowing for reuse and easy repair. The spacing between posts is quite flexible and less affected by uneven settling. Rope guardrails are aesthetically pleasing for scenic area roads. In snowy regions, they present less of a hindrance to snow removal.
