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.
