Noise control barrier is mainly used for reducing noise of roads, highways, viaducts, railways, factories, residential areas, industrial equipment and other noise sources.
Noise control barrier / sound barrier is made of steel pillar and absorbing sound and insulating sound board. One of important features of noise control barrier/sound barrier produced by Zhongdi is that the absorbing sound and insulating sound board consists of aluminum sheet (or galvanized sheet) and absorbing sound materials. The surface of board is treated by high voltage electrostatic spraying. It has anti ultraviolet and anti corrosion ability and various color choice. The absorbing sound board is often assembled with transparent panels to provide a better view and framework is built by standard steel. They cooperate with each other to form a unified effective whole in application.
The two sides of noise control barrier / sound barrier are sealed by EPDM, which play a continuous soundproof effect. If any damage occurs, two sides of board or one side of board can be exchanged and replaced, which reduce the cost of loss and improve the efficiency of products.

1. It has good absorbing sound performance. Noise reduction coefficient (NRC)≥0.90
2. It has waterproof performance. It can prevent deformation caused by damp environment.
3. It has strong impact resistance. It may be deformed but not pulverized when impacted.
4. It has light weight: 30kg/m2-35kg / m2
5. It has environmental protection: the products can be recycled, and the degree of secondary pollution is small.
Nowadays, We can provide sound insulation walls / sound barriers. The shape of noise control barrier / sound barrier is mainly erect, folded and arc.
