Two wave beam also called w-beam guardrail which is a kind of road crash barrier made as per M180 standard, 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.
Three wave beam also called thrie beam guardrail features its shape of three waves, which has an added corrugation on the basic of traditional W-beam made as per M180 standard. Compared to two-wave shape products, this one has a stronger construction and higher impact endurance. It is a perfect combination of high quality material and excellent anti-rust zinc or PVC coating. All of these make it outstanding at long-term corrosion and rust resistance.
