A guardrail structure having a plurality of vertical support posts (32) supporting a plurality of guardrail beams (42). Each post includes a pair of flanges (141, 142) having free edge portions with edge folds defining tubular beads (144, 146) on the free edge portions to provide reinforcement that result in a minimum amount of material usage for the posts. Spacers or blockouts (35D) may be mounted between the guardrail beams and the posts to offset the posts from the guardrail beams.

L'invention concerne une structure de glissière de sécurité comprenant plusieurs montants verticaux supportant plusieurs poutres de glissières. Chaque montant vertical comprend une paire de brides dotées de portions libres de bordures, qui pliées, définissent des nervures tubulaires permettant d'obtenir un renforcement résultant en une quantité minimale de matériau utilisé pour les montants. Des espaceurs ou des découpes de blocs peuvent être montés entre les poutres de glissière et les montants afin de décaler les montants des poutres de glissières.
