Characteristic

The sound barrier delivers three core performance advantages: efficient noise reduction, exceptional durability, and integrated ventilation and light transmission. Its design combines perforated metal panels with advanced sound‑absorbing layers, engineered through acoustic optimization to attenuate noise across diverse frequency bands — from low‑frequency engine rumble to high‑frequency tire hiss. The structure effectively reduces noise levels by 10–25 dB(A), meeting stringent highway and railway noise regulations. Each unit is built on a high‑quality metal substrate (aluminium or galvanized steel) and treated with triple anti‑corrosion technology: hot‑dip galvanizing, zinc‑rich primer, and durable powder coating. This layered protection ensures resistance to UV radiation, moisture, salt spray, and extreme temperature fluctuations, guaranteeing a service life of 15–25 years even in harsh coastal or industrial environments. Furthermore, the adjustable perforation pattern allows for natural ventilation and daylight penetration, preserving sightlines and air circulation around noise‑sensitive areas.

Application:

Transportation: highways, viaducts, railways, airports – ideal for reducing traffic noise in residential corridors and along critical infrastructure.

Industrial: power plants, chemical plants, machining workshops – contains equipment noise and protects workers and surrounding communities.

Municipal engineering: schools, hospitals, sensitive areas around residential districts – creates quieter learning, healing, and living environments.

Commercial facilities: noise reduction around large shopping malls and stadiums – improves visitor comfort and minimizes disturbance to adjacent zones.

Additional use cases include data centers, substations, music venues, and construction sites where temporary or permanent abatement is needed. The modular panel system allows for easy scaling and customization to fit any terrain or structural requirement.

Product Parameters:

Additional parameters include panel thickness (1.0–1.5 mm), standard dimensions (2440×1220 mm or custom up to 6 m length), acoustic performance (NRC 0.80–0.95, STC 25–35), and fire rating (Class A non‑combustible). All products comply with international standards such as ASTM E90, ISO 140, and EN 1793.
