The structure is perforated panels and perforated backplates, which rely on high-quality adhesive and aluminum honeycomb cores to be directly bonded to aluminum honeycomb laminate structures, with a sound-absorbing cloth attached between the honeycomb core and the panel and the back plate. Because the honeycomb core in the honeycomb aluminum plate is separated into a large number of closed chambers, preventing the air flow, so that the sound waves are obstructed, improve the sound absorption coefficient (can reach 0.9 or more), while improving the strength of the plate itself, so that the size of a single sheet can be made greater, further increase the design freedom. According to the indoor acoustic design, different perforation rate design, in a certain range to control the sound absorption coefficient of the combination structure, not only to achieve the design effect, but also can reasonably control the cost.rnBy controlling the perforated aperture, hole distance, and according to customer use requirements to change the perforation rate, the maximum perforation rate of 30%, aperture generally selected0.5mm、1.0mm、 2.0mm, 2.5mm, 3.0mm and other specifications, back plate perforation requirements and panel the same.

     1, the plate surface is large, high flatness

     2, plate strength, light weight

     3, sound absorption effect is good, fire proof, waterproof

     4, easy to install, each board can be separately disassembled, replaced 

      5, in size, shape, surface treatment and color, etc. can be customized according to customer needs, to meet customer personalized needs
