W-beam Highway Guardrail with Excellent Anti-corrosion and Long Service Life
W-beam highway guardrails are widely used for highway safety, and fixed on the side of the roads or middle of the road especially on curves and slopes for preventing vehicles from riding out from roads.


Features:
- The barriers ensure minimum damage to the vehicle and its occupants.
- During collision, the beam absorbs maximum energy by flattening out laterally and restrains the vehicle from veering over.
- Preventing vehicles from skidding back onto the carriageway by controlling exit angles through gradual deceleration and effective redirection of the vehicle back on to the road.
- To enable quick repairs in case of accidents.

Galvanized w-beam highway guardrail is highly resistant to corrosion.

Plastic coated guardrail beams have smooth surface and high wear-resistant performance.
Application:
- To provide railing protection to motor vehicles at dangerous road areas such as steep slopes, high embankments, obscure curves/bends, sharp corners.
- To absorb sudden impact during collision thus minimizing injury to vehicle and passenger.
- To act as a directional railing for vehicles moving in the right direction.
- To act as a median barrier for avoiding head on collision.
- To act as a protective barrier for pedestrians along the highway.

Galvanized guardrail barrier acts as a protector, because its high impact resistance.

Reinforced guardrail are usually set on the curves, which can effectively reduced the damage caused by accident.
