Glass Reinforced Plastic Highway Sound Barriers Corrosion Resistant
Glass Reinforced Plastic Sound Barrier For Viaduct In Microporous Railway District
Description
An acoustic barrier is a device inserted between the source and the receiver that causes a significant additional attenuation of sound wave propagation, thereby reducing the impact of noise in the area where the receiver is located.The design of sound barrier takes into full consideration the wind load of viaduct, urban light rail and subway, the impact of traffic vehicles and the all-weather open air corrosion protection.Hebei Jingchuang fiberglass Co., Ltd. has been committed to the research and development and innovation of fiberglass products for many years, and its products are sold well all over the world and enjoy a good reputation.The sound barrier is mainly composed of glass fiber reinforced plastics, perforated on the front, filled with rock wool inside, and pultruded FRP profiles on the back.It bears strong wind load, good acoustic.
Characteristic
It is beautiful and elegant in appearance, exquisite in production, convenient in transportation and installation, and long in service life. It is especially suitable for the use of anti-noise of elevated expressway, urban light rail and subway. It is an ideal sound insulation and noise reduction facility in modern cities.
The product selects material fine, the processing manufacture is careful, the product kind is much
