Easy-Install Perforated Noise Barrier Weather-Resistant for Municipal Road

This easy-install perforated noise barrier adopts prefabricated concrete base and steel frame, with perforated aluminum plate (open area rate 25%) as the outer layer and glass wool as the inner sound absorption material. The installation process requires no on-site welding, only bolt connection and module splicing, greatly shortening the construction period. The product has excellent weather resistance, withstanding -40℃ to 80℃ extreme temperatures, and waterproof grade up to IP65, suitable for outdoor municipal roads, overpasses, and viaduct noise reduction. It can be combined with guardrails and street lamps to form an integrated traffic supporting facility, enhancing project comprehensiveness.
