ABSTRACT:
A guardrail for a road or highway includes spaced uprights or posts on which are mounted deformable spacers which carry a longitudinal rail. The rail is formed by two wave shaped strips mounted together in a FIG. 8 profile by fastening ribs positioned in the open areas of the FIG. 8. The spacer has a straight lower portion that extends diagonally upward from the upright to the rail, a center portion fastened to the rail, and an upper portion curved to meet the upright. The spacer deforms to lift the rail upon impact. Additional tubular rails are provided on the uprights above the rail height.
