The Highway Aluminum Acoustic Barrier boasts unique features that set it apart from standard noise reduction solutions. Its 6061-T6 aluminum alloy core delivers an optimal balance of strength and lightweight design, making installation easy while providing robust resistance to impact and structural deformation. The powder-coated finish enhances aesthetic appeal and creates a protective layer against rust, corrosion, and environmental wear, ensuring the barrier maintains performance and appearance for decades. With an NRC of 0.9, it efficiently absorbs sound waves rather than reflecting them, minimizing echo and secondary noise pollution. The Class A fire rating ensures compliance with strict safety regulations, reducing fire spread risk in accidents. Its 120km/h wind resistance makes it suitable for coastal and high-wind areas, where traditional barriers may fail. Additionally, the modular design allows for easy expansion or modification, and low maintenance requirements mean minimal upkeep costs over its 25-year service life, addressing key pain points like long-term durability and effective noise control.
The Highway Aluminum Acoustic Barrier features precise technical specifications tailored for optimal performance. Each panel measures 3 meters in height and 2 meters in width, providing extensive coverage per unit. Constructed from 6061-T6 aluminum alloy, the panel has a thickness of 2mm, ensuring structural integrity while keeping weight manageable at 45kg per panel. The NRC is tested and certified at 0.9, with sound insulation capacity of up to 40dB, effectively blocking high-frequency traffic noises. It holds a Class A fire rating, meeting ASTM E84 standards for flame spread and smoke production. The powder-coated surface has a hardness rating of 2H, resistant to scratches and abrasions. Wind resistance is validated to withstand gusts of up to 120km/h, compliant with ASCE 7-16 wind load standards. The service life is rated at 25 years under normal outdoor conditions, thanks to the corrosion-resistant coating and durable aluminum material. Pre-drilled mounting holes are spaced 50cm apart along edges, facilitating quick and secure installation using galvanized steel posts. Custom color options are available upon request.
The Highway Aluminum Acoustic Barrier is ideal for a wide range of traffic noise mitigation applications. Primarily designed for highway and urban expressway projects, it is installed along roadside verges to protect nearby residential neighborhoods from constant traffic noise, creating a quieter living environment for families and reducing sleep disturbances and stress. It is also suitable for use on bridges and overpasses, where noise travels further due to elevated structures, affecting pedestrians and adjacent buildings. Commercial zones such as shopping centers, office parks, and schools located near busy roadways benefit from this barrier, as it maintains a peaceful atmosphere conducive to business operations and learning. Additionally, it can be used in industrial areas adjacent to highways to reduce noise interference with manufacturing processes. Approved for use by transportation departments, urban planning agencies, and private construction firms, it complies with local and international noise control regulations, making it a versatile solution for any outdoor noise reduction project.
