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.
