It adopts precision numerical control perforation process, the perforation diameter is 3mm-5mm, and the perforation rate can be adjusted from 20% to 30% as needed. The sound absorption coefficient reaches 0.75 (1000Hz), which effectively improves the indoor acoustic environment and reduces echo and reverberation time. The surface is treated with electrostatic powder coating, and the color can be customized, which combines beauty and durability. The Class A1 fire rating meets the safety requirements of public buildings. The suspended installation structure reserves enough acoustic cavity to improve the sound absorption effect. It is easy to clean and maintain, and the perforated surface is not easy to accumulate dust.
The standard length of a single tube is 6 meters, which can be cut to any length. The thickness ranges from 0.8mm to 1.5mm, the width ranges from 50mm to 200mm, and the height ranges from 60mm to 180mm. The perforation diameter can be customized from 2mm to 8mm, and the perforation patterns include round, square, diamond and other optional options. The installation spacing is 100mm-250mm. It is equipped with special sound-absorbing cotton and hanging keels, and the acoustic cavity height is ≥150mm to further improve the sound absorption performance. The weight per meter is about 2.8kg for the specification of 1.0mm thickness, 80mm width and 120mm height.
It is widely used in multifunctional conference rooms, academic lecture halls, cinemas, libraries, recording studios and other places with high acoustic environment requirements. It can also be used for ceiling decoration of school classrooms and public corridors of office buildings to reduce environmental noise and improve space comfort. At the same time, it has good decorative effect and matches the design style of modern office and education places.
