Industrial factory noise barrier, 4.0m high. Sound-absorbing steel panel with mineral wool core. NRC 0.85, STC 34. For power plants, steel mills, cement plants, heavy industry. MOQ 100 m2, 10-20 day delivery.
Industrial factory noise barrier walls are heavy-duty acoustic structures engineered for high-noise industrial environments. The 4.0m height provides enhanced noise reduction for tall industrial equipment and multi-story noise sources — exceeding the 3.0m highway standard by 33%.
## Why 4.0m for Industrial?
Industrial noise sources differ from traffic noise: - **Taller Sources**: Factory buildings, cooling towers, and stacks emit noise at 10-20m height. 3.0m barrier insufficient. - **Lower Frequencies**: Industrial equipment (compressors, generators, presses) produces more low-frequency noise than traffic. Requires thicker panels. - **Continuous Exposure**: Industrial noise is 24/7, not intermittent. Higher barrier reduces cumulative exposure. - **Multiple Sources**: Factory perimeters face noise from multiple simultaneous sources. Taller barrier creates larger shadow zone.
## Acoustic Construction
- **Traffic-Side Face**: 0.8mm perforated galvanized steel (allows sound entry) - **Core**: 80mm mineral wool insulation (100 kg/m3 density — heavier than highway grade) - **Interior Face**: 0.6mm solid galvanized steel (sound barrier) - **Frame**: 2.0mm galvanized steel edge channel (heavier than highway grade) - **Acoustic Performance**: NRC 0.85, STC 34, IL 12-18 dB(A)
## Key Advantages
- **Enhanced Noise Reduction**: 12-18 dB(A) insertion loss — reduces perceived loudness by 60-80% - **Industrial-Grade**: 80mm core + 100 kg/m3 density — handles low-frequency industrial noise - **Weatherproof**: Galvanized steel + moisture-resistant mineral wool. 20+ year outdoor life. - **Modular**: Standard panel 2.0m x 0.5m. Any length/height achievable. - **Structural**: Heavier frame and posts (HEB 120) for industrial wind loads and potential impact. - **Fire Resistant**: A1 non-combustible. Meets industrial fire codes. - **Chemical Resistant**: Optional PVC coating for corrosive environments (chemical plants, coastal).
