1.The barriers ensure minimum damage to the vehicle and its occupants.

2.During collision, the beam absorbs maximum energy by flattening out laterally and restrains the vehicle from veering over.

3.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.

4.Enables quick repairs in case of accidents.

5.All components are galvanized for longer life.
