Thrie Beam Guardrails - Tri Beam Guard Rails Strengthened
Thrie-Beam Guardrails are a type of guardrail system with three alignment, w-shaped steel beams supported by posts and blocked at the two sides to form a continuous structure. It is mainly used for median and side barrier on highways, pedestrian, and roadside safety barriers. It is designed to absorb more energy from impact and provide better protection than traditional W-beam guardrail. Additionally, Thrie-Beam Guardrails have distinct advantages over other guardrail systems, such as weight savings due to reduced material compared to W-beam guardrail. It is also easier to install since the rails come pre-assembled in sections, so it requires less labor time. Furthermore, its reduced profile allows a larger range of view for drivers approaching curves in highways, as well as reducing soil erosion.
Thrie Beam Guardrail is also known as Tri Beam Guardrail or Three Waves Guardrail. Thrie beam guard rails have an additional beam or wave compared with W beam railings, suitable for safety barrier systems demanding superior strength. We supply Thrie Beam Guardrails with three wave beam plates, thrie beam terminal ends, posts, spacers / blockouts, anti dazzle board and bolts for the complete highway safety barrier project.
