Muffler color steel panel
The surface of the sound-absorbing board is covered with holes of different depths, shapes and apertures.
Because the sound-absorbing composite board panel is made of perforated color steel and the core material is made of 120kg/m'rock wool composite molding, it can well prevent air flow, hinder sound waves, improve the sound absorption coefficient, and improve the board itself.
