Description ·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. · It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, splicing, simple construction, good stability, strong impact resistance, good independence, and high cost performance.
