    price: contact company for price

    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.

      The guardrails can be traditional beam type solid guardrail panels or economic cable guardrails.

      The steel guardrail panels are made of corrugated plates in symmetrical shapes of waves.

      It is either concave (bowing away from the traffic lane) or convex (bowing towards the traffic lane).

      The guardrail beams we supply are 10 gauge and 12 gauge materials, ranging from 5’ to 60’ radius.

      Made from strip steel coils, the guardrail panels have a normal thickness of 2mm to 10mm.

      Where the Guardrail Barriers are Used:

      Highway guardrail is commonly used as a passive barrier system for highway traffic security.

      The steel guard railings are installed widely along the roadway and highways, especially at curves and slopes, parking lots, road corners, dead end street and other site that may cause danger or accident to people or cars.

      How the Guardrail Panels Work:

      Guardrail panels fixed along the expressway can guide the direction of the vehicles and keep them running within the safe limit.

      In case any traffic accidents happen such as vehicle collision, the guardrail barrier will play an important role by decelerating the speed of the collided vehicles.

      Due to the designed curved shape of the guardrail panels, they will allow a slowing down of the crashed vehicle without hurting it seriously.

      In this way, the guard rails can reduce the danger level of the involved vehicles by keeping them safely within the road, allowing them slow down and directing them back to the right way.

      What are popular surface treatments for the guardrail beams:

      We supply three types of steel guardrail beams according to the finishes:

      Common galvanized steel guardrails , zinc coating quantity at about 550 gram/ m2 (40µ);

      Heavy hot dipped zinc plated guardrails, zinc coating quantity at about 1100 g/m2 (80µ) or 1200 g/m2 (85µ);

      PVC coated steel highway guardrails.

      Functions of the Surface Treatments to the Finished Guardrail Panels:

      Steel galvanized guardrail coated with zinc offers more durability and maximum strength.

      The zinc coating also prevents discoloration and weak points caused by rust and corrosion.

      The zinc or PVC coating enables the following five features for the steel guardrails:

      1, Anti-rusting;

      2, Anti-corrosion;

      3, Longer service life with protective coating layer;

      4, Ultraviolet proof;

      5, Anti-aging.

      Type I.

      W-beam guardrails

      Type II.
