The three wave-shaped beam guardrail is an enhanced form of semi-rigid metal fencing for expressway and highway traffic guarding. Compared with the W-beam guardrails, the thrie beams cost high while offering more strength and better collision protection. Thrie-Beam Steel Guardrail is essentially two pieces of W-Beam Guardrail formed into one single piece structure. It is used in specific circumstances where additional coverage may be necessary, such as highway uses.

It works in a form of a continuous corrugated steel structure composed with waved steel guardrail panels connected together and supported by the posts. The beam guardrail works by adsorbing the crashing energy through the base, posts and the beams.
