Waveform beam guardrail plate and waveform beam steel guardrail

摘要

A waveform beam guardrail plate and a waveform beam steel guardrail are provided. In which, the guardrail plate includes a main body (15) and two rings (16, 17) with a same structure installed axial symmetrically on an upper and a lower edges of the main body; furthermore, a transverse section of the main body has an arc shape, and the upper and lower edges of the main body of the guardrail plate are curled inwardly and helically toward a protruding direction of the main body of the guardrail plate for forming the two rings (16, 17). The waveform beam steel guardrail includes numbers of guardrail plate units (1, 11), upright posts (2) and preventing blocks (3), and the guardrail plate units (1, 11) are connected with the upright posts (2) by the preventing blocks (3).
