Impact-resistant beam for guardrail-type crash barriers

摘要

The beam comprises an impact-resistant channel supportable on a row of upright posts (12). The channel incorporates stiffeners (30), each of which has an outer profile matching with the inner profile of the channel (20) along three walls thereof. Each stiffener consists of a metal plate (30) having a main wall (32) arranged transversely to the channel, and lateral, square-bent edges (34, 36, 38, 40) matching with three corresponding walls of the channel (20).
