Galvanized or Aluminum Noise Barrier for Highway and Railway

Micro hole noise barriers are installed on the railway.
PMNB-1: Noise barrier is widely used in the highway and railway for absorbing noise.

Noise barrier, also called sound barrier, is a type of fence barrier used in the highway, railway, residences and other places for sound insulation and reduction. Perforated metal noise barrier with light weight, firm structure durable and other features are popular in both industrial and commercial applications. Here are the detailed information of noise barrier, refer to them and choose the perfect one you like.

Structure of noise barrier
Noise barrier is a three-layer structure.

  • The first layer is the perforated metal sheet. The common material of perforated metal sheet is aluminum. Mild steel, galvanized steel or powder coated steel sheet are also available. The hole type of perforated metal sheet can be micro holes or louver holes.
  • The second layer is sound absorbing material infill. The sound absorbing material has excellent sound or noise absorbing performance, it can reduce the noise and keep quite. The main infill material is glass wool. Other absorbing materials are available.
  • The third layer is metal sheet. The material of metal sheet is same as the perforated metal sheet. But there is no any hole on the metal sheet.
Several pieces of glass wool are placed into the noise barrier.
PMNB-2: Glass wool is mainly for absorbing noise.
