The straight W-beam guardrail can be lined up for transitioning smoothly and is suitable to the curves with a radius greater than 45m. For the radius less than 45m, the pre-curved W-beam guardrail product exploits its advantages to a full.

W beam guard railings can be used in expressway and highways to absorb maximum energy of the impact force when collision occures and reduce harms to cars and people. It can also protect the vehicles against skidding off roads, especially mountain roads and bridges and prevent the pedestrians from the danger of walking across highways.
