The double-layer structure consists of a perforated 6063 aluminum alloy panel and centrifugal glass wool filling, providing a combination of sound absorption and insulation functions to reduce traffic noise by ≥35dB, effectively blocking high-frequency vehicle engine noise and low-frequency tire noise. The 6063 aluminum alloy panel has a UV-resistant coating with UV50+ protection, preventing fading and aging under long-term sunlight exposure, and its corrosion-resistant properties ensure a service life of ≥15 years in outdoor environments. The oval hole design with a 10mm diameter and 38% opening rate optimizes sound absorption efficiency while maintaining structural stability, preventing glass wool leakage. The centrifugal glass wool filling is non-toxic, odorless, and fire-resistant (B1 grade), ensuring environmental friendliness and safety. The modular design allows for on-site assembly, reducing construction time by 30% compared to traditional noise barriers, and it can be easily replaced in damaged areas without affecting the entire barrier system.
Each modular panel has dimensions of 2000mm×1000mm, with a total thickness of 100mm (including 80mm centrifugal glass wool filling and two 10mm thick aluminum alloy panels). The aluminum alloy panel is made of 6063 grade, with a surface treatment of electrostatic powder coating with UV-resistant additives. The hole type is oval, with a long axis of 10mm and a short axis of 6mm, resulting in an opening rate of 38% to maximize sound absorption efficiency. The noise reduction rating is ≥35dB, meeting GB/T19889.3-2005 noise barrier performance standards. The fire rating is B1 grade, ensuring flame retardant performance in case of accidental fires. The operating temperature range is -30℃ to 70℃, ensuring stable performance in extreme cold and heat. The product weighs approximately 18kg per square meter, minimizing the load on supporting structures. It passes national traffic infrastructure material certification and has a weather resistance of ≥10 years without significant performance degradation.
Ideal for noise reduction projects along highways, urban expressways, high-speed railways, and suburban railways, where it reduces traffic noise pollution by ≥35dB, improving the living quality of residents in nearby residential areas, schools, and hospitals. It is also suitable for industrial park boundaries to reduce factory equipment noise and protect nearby residential areas. The modular installation system allows for quick construction during traffic infrastructure expansion projects, minimizing road closure time and impact on traffic flow. In coastal regions, its corrosion-resistant properties effectively defend against sea salt mist erosion, extending the service life of the noise barrier. For urban landscape projects, custom color options are available to match the surrounding environment, balancing noise control with aesthetic appeal. Additionally, it can be used for airport peripheral noise reduction to reduce aircraft takeoff and landing noise, protecting nearby communities from noise interference.
