W-beam guardrail has a section or profile of W shape, it is also named as two wave beam guardrail. This is the major type of beam barriers for highways safety with symmetrical designs on each side of the beam. We supply two kinds of finishes for W beam guardrail panels: hot dipped zinc coating or plastic coating. According to the fabricated shapes, our W-beam guardrails can be divided into two types: the straight line w-beam,or the curved beams.
How to choose straight W beam or Curved Beam used for your uses?
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.
