Metis Flow Metal
Our galvanized steel noise barrier wall adopts a three-layer composite structure: outer galvanized steel plate (thickness 1.5-2.0mm), middle glass wool sound absorption layer (density 48kg/m³), and inner perforated plate (aperture 3mm). The overall sound insulation effect reaches 35-40dB, effectively blocking low-frequency traffic noise (50-2000Hz) from highways, railways, and interchanges. The galvanized steel surface is treated with electrostatic spray coating, corrosion resistance grade up to C3, service life up to 25 years. Standard module size 2.0m (width) × 3.0m (height), supports on-site splicing to form large-scale noise barrier systems, widely applied to transportation infrastructure noise control projects.
