The aluminum strip gap sound-absorbing board is the only type of sound-absorbing material on the market that is assembled using aluminum profiles and has a surface with slot holes. Its appearance features long, narrow grooves. When installed in large areas, the overall effect is very ideal. The surface can be powder-coated in pure colors, transferred with various wood-grain or stone-pattern designs, and even electroplated with metallic colors. Almost all conceivable surface effects can be achieved.
