Hot Dipped Galvanized Beam Guardrails Highway Safety Barrier System


Shanda supplies a complete system for highway security and construction uses. We supply galvanized steel guard rails used for traffic control in highways. Typical forms of beams are W beam and Thrie Beams. The guardrail two wave and three wava panels can be used together with Highway Noise Barrier System, or the metal security fencing system.

Work Principle:
Steel beam guardrails are designed to ensure minimum damage to the vehicle and its occupants. The waved metal panels can absorb maximum energy by flattening out laterally and restraining the vehicles from veering over during the collision. Once accidents happen, the guardrails will help prevents the vehicle from skidding back onto the carriageway by controlling exit angles through gradual deceleration and effective redirection of the vehicle back on to the road.
