Ultra-Microporous Pinhole Plate

Ultra-microporous pinhole plate is also called triangular pinhole plate, has a thickness of 1mm aluminum plate and a mesh size of 0.15mm,the maximum width is 1250mm. It is commonly used as an environmental noise control barrier in transportation and municipal facilities such as highways, railways, and subways that cross urban areas. It is also used as a sound insulation and noise reduction board for building walls, generator rooms, factory buildings, and other noise sources. It can also be used for sound absorption of ceilings and wall panels in buildings. The sound absorption effect of ultra-micro porous sound-absorbing aluminum plate is more than 30% higher than that of traditional perforated aluminum plate.
