Global urbanization and transportation infrastructure expansion have made traffic, railway and industrial noise pollution a prominent environmental problem. Long-term high decibel noise disturbs residents’ daily life, reduces work efficiency and fails to meet municipal environmental protection standards. Traditional simple partition walls only provide weak sound insulation, with poor weather resistance, easy water accumulation and low noise reduction efficiency. To solve the pain points of insufficient sound absorption, short service life and complicated construction of ordinary noise isolation structures, our factory launches full-series modular Noise Barrier (Sound Barrier / Acoustic Barrier) products, providing high-efficiency noise reduction, wind-resistant and anti-corrosion acoustic isolation solutions for global highway, railway, viaduct and factory noise control projects.
Main Classification & Structural Characteristics
We supply three mainstream noise barrier series to cover all traffic and industrial application scenarios.
1. Perforated Metal Sound Absorbing Noise Barrier
The most widely used standard type. Front panel adopts galvanized aluminum/steel perforated plate, with internal fire-retardant hydrophobic glass wool or rock wool filling. Perforations guide sound waves into the inner absorption layer to convert noise energy into heat, with excellent medium and low frequency noise reduction performance. Thickened metal frame and column support strong wind resistance, suitable for highways, urban roads, railways and factory boundary noise isolation.
2. Transparent PC/Acrylic Noise Barrier
Light-transmitting sound insulation panel made of polycarbonate or PMMA acrylic material, light transmittance over 80%. It avoids the closed, depressing visual effect of full-metal barriers, maintains road landscape and driving sight, and is widely used for urban viaducts, landscape highways, bridge decks and residential roadside sections. High impact resistance, anti-aging and not easy to crack under long-term sunlight exposure.
3. Combined Hybrid Noise Barrier
Combines lower metal sound-absorbing panels and upper transparent acoustic panels. Balances noise reduction efficiency and landscape permeability, the optimal solution for municipal urban trunk roads, overpasses and scenic traffic lines. Custom curved top design optional for extra 3–5dB noise improvement.
Raw Material & Multi-Layer Anti-Corrosion Treatment
- Outer Panel: Hot-dip galvanized steel plate, aluminum alloy plate, transparent PC/acrylic sheet; surface polyester powder coating, anti-UV, anti-fading, anti-rust for 15–20 years outdoor service.
- Sound Absorbing Core: 50–150mm high-density hydrophobic glass wool/rock wool, Class A fire retardant, no water absorption, no mildew, stable sound absorption coefficient long-term.
- Back Plate & Support Column: Thickened galvanized steel, fully welded and polished, all bolts and accessories hot-dip galvanized to prevent local rust failure. All materials support customized thickness, color and panel size according to project drawings. Coastal high salt fog areas can choose full aluminum alloy or stainless steel accessories for extended service life.
Core Product Advantages
First, dual sound absorption & insulation performance. Composite structure realizes efficient interception of traffic and mechanical noise, noise reduction range 25–40dB, effectively improving surrounding living environment. Second, superior weather and wind resistance. Modular reinforced frame withstands 12-level typhoon wind load, stable structure without deformation, applicable to all climate zones. Third, long service life & low maintenance. Double-layer anti-corrosion metal panel + hydrophobic sound-absorbing cotton, no frequent replacement, only simple surface cleaning required. Fourth, fast modular installation. Prefabricated standard panels, on-site splicing without complex welding, greatly shortening project construction cycle; single damaged panel can be replaced separately to reduce maintenance cost. Fifth, diversified landscape matching. Multiple colors, curved shapes and transparent combinations available to coordinate with urban architecture, roads and park landscapes.
Wide Application Scenarios
Transportation engineering: Highway, urban viaduct, railway, subway line, bridge deck noise isolation. Industrial environmental protection: Factory workshops, compressor stations, power plants, mechanical processing plants, logistics yards noise control. Municipal supporting: Residential districts, schools, hospitals, park surrounding noise protection, scenic road landscape sound barriers.
Global Customization & Export Service
We provide full customization of barrier height, panel thickness, sound absorption grade, color, top shape and installation accessories based on customer project parameters and terrain conditions. Free technical construction drawings, acoustic test reports and sample support are offered for engineering tender verification. Strict pre-shipment inspection of panel flatness, coating adhesion, sound absorption performance and wind resistance structural strength. Products wrapped with waterproof film and loaded into export fumigated wooden pallets, supporting mixed container loading with guardrails, anti-slip plates and filter elements to save ocean freight. Our noise barriers are exported to Southeast Asia, Middle East, Europe, Australia, Africa and South America, maintaining long-term stable cooperation with municipal engineering contractors, environmental protection companies and traffic infrastructure suppliers worldwide.
