Hot Dipped Galvanized W - Beam Highway Metal Guard Rails For Road Safey Barrier
Product Description:
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.

The grades of collision avoidance grades of corrugated highway guardrails can be divided in to A-class and S-class. S-class guardrails are enhanced for the roadside of particularly dangerous road sections. A grade guardrails are for accommodation highways. The grades of collision avoidance grades of common roadside guardrails cam be divided into 5 classes: B, A, SB, SA and SS.
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.

Function of W-Beam Guardrails:
I. Blocking: They can prevent vehicles and pedestrians from entering an area where they should not be.
II. Isolation: Separate cars, non-motor vehicles and pedestrians into different traffic lanes. Thus improving traffic safety for all.
III. Warning: they are usually installed with some sort of reflectors attached in order to alert drivers of their presence, particularly at night.
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.
