This galvanized steel composite sound-absorbing perforated metal panel is specially designed for industrial machine rooms, highway sound barriers, and urban rail transit noise reduction, adopting a composite structure of galvanized steel and centrifugal glass wool, combining excellent sound insulation and noise reduction performance with structural strength. Its micro-hole perforated structure can effectively absorb sound waves in the air, and the centrifugal glass wool interlayer further blocks sound wave transmission, with a sound insulation level of over 35dB, which can significantly reduce the impact of industrial equipment noise and traffic noise on the surrounding environment. Complying with national Grade A fire safety standards, it has good corrosion resistance and a service life of over 20 years, making it a core material for industrial noise reduction and urban acoustic environment management. Custom sizes and sound insulation levels are available according to different scene requirements.
