Three-beam guardrail are essentially to w-beam shaped structures side by side to form a large single structure. When compare to w-beam guardrails, the three-beam safety barrier design is stronger and can withstand larger impact forces.
We use only the finest quality raw materials to construct these highway guardrail barriers. They undergo surface treatments (zinc or PVC coating) to increase corrosion resistance.
Three-beam guardrails are often used as roadside barriers for transition to high speed roads.
Three-beam guardrails are built in different shapes and sizes depending on the location of their installation. We produce straight and curved three-beam guardrails.
