Compared with ordinary outdoor acoustic materials, this product uses hidden hanging installation, which improves the overall aesthetic effect of the building facade. The 15% perforation rate is optimized for traffic and industrial noise frequencies, achieving efficient sound absorption. The 2.5kPa wind pressure resistance meets the safety requirements of elevated buildings and outdoor curtain walls. The fluorocarbon coating has a service life of more than 15 years in outdoor environments, reducing later maintenance costs. The Class A fire rating meets the fire safety requirements of outdoor building engineering, and the lightweight design reduces the bearing load of the building.
The base material is 3003 aluminum alloy with a thickness of 1.5mm, with a perforation hole diameter of 3mm and a perforation rate of 15%. The total thickness of the panel is 25mm with a built-in 20mm rock wool sound absorption layer. The standard size is 1500x3000mm, and the weight per square meter is approximately 6.8kg. The surface is treated with fluorocarbon powder coating, which has passed 1500 hours of salt spray resistance test. The wind pressure resistance is 2.5kPa, and the waterproof rating is IP65. The sound absorption coefficient αw reaches 0.72, and the color can be customized according to customer needs.
This product is suitable for outdoor acoustic treatment projects such as highway noise barriers, elevated rail transit noise barriers, commercial building curtain walls, outdoor square sound insulation walls and industrial park peripheral sound barriers. It can effectively reduce traffic and industrial noise, improving the acoustic environment of surrounding areas. Its excellent weather resistance and corrosion resistance make it suitable for long-term use in various complex outdoor environments.
