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.

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.
