W-Beam Guard Rail is a highway safety barrier system used on roads, motorways, and elevated road sections. Its W-profile corrugated steel beam is mounted on steel posts and designed to absorb and redirect vehicle impact energy, helping contain errant vehicles and prevent them from leaving the roadway or crossing into opposing traffic.
