Aluminium noise barrier is designed to use in the acoustic environment of highway, expressway, railway or roadside to reduce the traffic noise. The metal aluminum structure built in with fabrics or fibers offers excellent noise absorption, fire retardant property and wind loading property. We offer reliable aluminium perforated sheet solution for Architectural and Highway, Expressway and City Constructional Noise Control Projects. The noise barrier panels can be installed along the guardrails to form a dual system reducing wind and noise at the same time ensuring highway traffic safety.
Aluminum Highway Noise Barrier is composed of alloy frame, perforated plate, built-in absorbent cotton, H post and flange plate.. Suitable for sound insulation and noise reduction for High-speed Rail, highway, municipal, rail transportation.
