Fabric Wrapped Metal Plate Wall Acoustic Fencing

Higway sound barrier wall panels are made of metal plates or non metal economic PC sheets. The plates are use together with sound insulation materials to achieve enhanced noise reduction effect. The acoustic walls uses metal and non metal plates wrapped with fire resistant polyester wool or fabrics.
