Highway Guardrail Project Cases
The highway crash barrier is used to prevent errant vehicles from running out of the roads and impacting roadside buildings or other objects. It is most commonly fixed on the side of the highways, dock areas, and aisles, especially on curves and slopes for protection against run-off-road collisions. The galvanized W-Beam is the most common highway guardrail, which are longitudinal highway barrier designed to reduce the severity of run-off-road collisions.
