frp acoustic barrier The main parts are steel posts and the sound barrier. The steel post is stressed member which are fixed on the armor plate embedded in advance by welding or bolting.The sound barrier is the main component for sound insulation which is fixed in the H type slot by high spring clips.It is the most ideal method to insulate the noise in modern city today with beautiful appearance and it is easy to transport and maintain with long life.The novel design of the construction is that sound absorption plates are used on the top and bottom which can weaken the diffraction of the noise effectively and water white reflective sound barrier is used in the middle which can interrupt the transmission route of sound wave and it can give the driver and dweller along the road a wide sight. Features: 1, Novel structure and no rust2, High strength, bending strength ≥2.34KN/m2 and no deformation;3, Light weight (weight: 16kg/m2),4, Different shapes may be designed as per buyer's requests5, Noise reduction coefficient NRC ≥ 0.8; or sound insulation capacity Rw ≥ 28dB (A)6, Easy maintenance, no color changing, easy washingCurrently the products have been applied in the sound barrier projects along the railways, expressways and subways. The products with size of 300 mm (H) * 80 mm (thick) * L (length) are available with the length to be customized according to customer requirements.
