2. Space distance: The barrier post often installed with spacing from 6.3 to 32.6 ft. The longer spacing normally means the higher deflection distance.
3. Tensioning: Cables are fixed on the post and tightened to specific tension in accordance with the local temperature and environment. After tension, the reflection will be reduces and the ability to preventing vehicles from skidding off the road can be enhanced. Normally the tensions values range approximately from 2,000lb to 9,000lb.
Rope guardrail is the main representative form of flexible guardrail. It is a structure composed of several ropes that exert initial tension and are fixed on the column. It mainly relies on the tensile stress of the rope to resist the collision ofvehicles and absorb the collision ability.
