This invention relates to a plastic guardrail, extruded into a structure having multiple layers and ribs between the layers using a thermoplastic resin, and configured such that an outer layer using a material having high strength to increase impact resistance, and an inner layer and the ribs using a material having lower strength than that of at least the outer layer to increase an internal cushioning effect are integrated with each other through a double extrusion process. The guardrail of the invention can exhibit both impact resistance and a cushioning function.
