CASTING COMPOSITE FOR RAIL OF GUARD RAIL CASTING FOR RAIL OF GUARD RAIL AND GUARD RAIL WITH STRUCTURE FOR SHOCK ABSORPTION AND CLIMB-OVER PREVENTION USING THE SAME

摘要

The present invention relates to a guard rail with a structure for shock absorption and climb-over prevention and a rail material that is a component of the guard rail, which can relieve the shock of a vehicle through plastic deformation of a partial structure and multiple buffer structures in case of a vehicle collision, and protect a driver by preventing the vehicle from climbing over and overturning.
