W-Beam Crash Barrier

    • W-Beam Crash Barriers are safety barriers used on roads and highways to prevent vehicles from leaving the roadway and colliding with obstacles or entering opposing traffic lanes.
    • They are typically made of galvanized steel and consist of a series of W-shaped beams.


  • Material: Galvanized steel for corrosion resistance.
  • W-Beam Design: The W-shaped profile provides strength and energy absorption during collisions.
  • Post Structure: Supported by sturdy posts, often spaced at regular intervals.
  • End Treatments: Special end sections absorb impact energy and redirect the vehicle.
  • Reflectors: Reflective elements enhance visibility during low-light conditions.


  • Highways and Roads: Installed on medians, edges of roads, and bridges to enhance road safety.
  • Turns and Curves: Used to guide vehicles and prevent collisions on curves.
  • Toll Booths and Interchanges: Enhances safety in areas with high traffic flow.

Variants with Technical Specifications:

Standard W-Beam Crash Barrier:
    • Beam Dimensions: W-shaped beams with specific dimensions.
    • Post Spacing: Typically spaced at regular intervals, e.g., 3 meters.
    • Thickness: Varies based on design standards, commonly 2.67 mm.
Thrie-Beam Crash Barrier:
    • Beam Design: Thrie-beam profile for enhanced containment.
    • Applications: Suitable for areas with a higher risk of vehicle crossover.
    • Post Structure: Similar to the standard W-beam, with added reinforcement.
