Composite Material Noise Barrier Wall Corrosion-Proof for Coastal Traffic Route

The composite material noise barrier wall combines fiberglass-reinforced plastic (FRP) outer plate and polyethylene foam sound absorption layer, corrosion resistance grade up to C5-M, specially designed for coastal and humid areas. The FRP material resists salt spray erosion and moisture damage, service life up to 30 years in coastal traffic routes and wetland surrounding projects. The sound insulation effect reaches 32-38dB, blocking traffic noise while ensuring air permeability (air flow rate ≥0.3m³/(㎡·s)). The product is lightweight and earthquake-resistant, suitable for areas with high humidity, strong corrosion, and complex geological conditions, and can be used with drainage punching plates and geogrids to form a comprehensive engineering solution. It has passed ISO 9001 quality certification and CE certification, reliable for export-oriented noise control projects.
