Perforated metal mesh is a mesh material with regularly spaced holes punched into the surface of metal or non-metal sheets using a stamping process. It is commonly made of stainless steel, low-carbon steel, galvanized steel, and PVC, and its core function is sound insulation and noise reduction. The hole shapes include more than twenty types, such as round holes, diamond holes, and staggered holes. The sheet thickness ranges from 0.2-20mm, and the hole diameter ranges from 0.5-200mm. It is widely used in traffic and municipal noise barriers, building sound-absorbing wall panels, machinery protective covers, and decorative building materials.
Perforated metal mesh refers to perforated metal with holes of different shapes punched into the same material to meet various needs. It can be used as an environmental noise control barrier in transportation and municipal facilities such as highways, railways, and subways passing through urban areas, as well as a sound-absorbing panel for sound insulation and noise reduction in building walls, generator rooms, factory buildings, and other noise sources.
