About this product
Product information from the supplier.
Our premium Bridge Noise Barriers are engineered to provide superior acoustic insulation for highways, railways, and urban infrastructure. By utilizing a sophisticated blend of reflective and composite sound insulation technologies, these barriers effectively mitigate traffic noise, protecting nearby residential areas and improving the overall quality of urban living environments.
Designed for versatility and durability, our noise barriers are available in multiple materials including perforated aluminum, stainless steel, and acrylic. Whether you require a high-performance sound-absorbing core for industrial sites or a transparent aesthetic for municipal bridges, our customizable solutions ensure maximum noise reduction coefficients (NRC) and exceptional wind resistance for long-term stability.

Frequently Asked Questions
Q: What is the difference between reflective and composite sound barriers?
Reflective barriers simply block and bounce sound back, while composite barriers combine a perforated outer layer with sound-absorbing infill to both absorb and block noise, providing a much more effective solution.
Q: Can these noise barriers be customized for specific project dimensions?
Yes, we offer full OEM/ODM customization. You can specify the metal thickness, panel height, length, color, and the specific shape (such as top arc or vertical) to meet your project requirements.
Q: Which materials are best for high-humidity or coastal areas?
For coastal or high-humidity areas, we recommend stainless steel or aluminum alloys due to their superior natural corrosion resistance compared to carbon steel.
Q: How is the wind resistance of the noise barrier measured?
Wind resistance is measured by calculating the vertical and horizontal force and the bending moment relative to wind pressure values (KN/M2) and the height of the installation.
Q: What is the Noise Reduction Coefficient (NRC)?
NRC is a scalar representation of the amount of sound energy absorbed by a surface. Our composite barriers achieve high NRC values (up to 0.84), meaning they absorb a significant portion of incident sound.
Q: Where are these barriers typically applied?
They are primarily used along expressways, elevated roads, urban light rails, subways, bridge edges, and industrial factory boundaries to reduce noise pollution for residents.
