Midwest Guardrail System

highwayssafer

MGS (Midwest Guardrail System), which has redefined the entire W-beam guardrail industry and is recommended by the Federal Highway Administration: We believe that States should consider adopting 31-inch guardrail as their standard because these systems exhibit superior performance at little or no additional cost which is a direct reflection of the 31-inch tall MGS. MGS is currently installed in a number of demanding applications, including at high flare rates (5:1), adjacent to steep 2:1 slopes, over long-spans culverts, on bridges as bridge rails, and in attachments to temporary concrete barriers.
