W-beam Guardrail

W-beam guardrail is a kind of road crash barrier used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects. So it is most commonly fixed on the side of the highways, dock areas, aisles, especially on curves and slopes for protection against run-off-road collisions.

Thrie-beam Guardrail

Thrie beam guardrail features its shape of three waves, which has an added corrugation on the basic of traditional W-beam. Compared to two-wave shape products, this one has a stronger construction and higher impact endurance. It has been successfully impact-tested by a heavy truck and has showed its remarkable resistance against the crash force.
