Zhongtai Automotive Sound Barrier China Manufacturers Acoustic Barrier 2500mm Railway Noise Barrier

ZHONGTAI Automotive Sound Barrier China Manufacturers Acoustic Barrier 2500mm Railway Noise BarrierProduct IntroductionSound barriers are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers that are pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to wall structures installed beside railways and highways to reduce the impact of traffic noise on nearby residents.Soundproof walls are also called sound barriers, which are divided into traffic soundproof barriers, equipment noise attenuation soundproof barriers, and industrial factory boundary soundproof barriers. Roads and highways are the places where most types of sound barriers are used.Perforated metal sound barrier specificationsMetal material: aluminum, steel, stainless steel, copper.Metal plate thickness: 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm.Three-layer sound barrier thickness: 80 mm, 100 mm.Width: 1220 mm, 2100 mm.Weight : 0.8 kg/m2, 1.2 kg/m2, 1.4 kg/m2, 1.6 kg/m2, 1.9 kg/m2, 2.2 kg/m2, 2.4 kg/m2, 2.6 kg/m2, 3.0 kg/m2, 3.3 kg/m2.Colors: Clear, lake blue, green, blue, opal, brown, silvery gray, red.Note: Any size or color can be customized according to your requirements.Aluminum noise barrier specificationsMetal material: aluminum steel.Three layers structure:The first layer is a perforated aluminum sheet.The second layer is sound-absorbing material infill.The third layer is a non-perforated aluminum sheet.Metal plate thickness: 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm.Barrier forming thickness: 80 mm, 100 mm, etc.Length: 1960 mm, 2460 mm.Width: Commonly is 500 mm.Note: You can customize it according to your requirements.  PVC sound barrier specificationsMetal material: aluminum or steel sheet.Filling: EPDM, fiberglass, or aluminum foam.Metal sheet thickness: 0.8 mm-1.0 mm.Length: 1960 mm, 2460 mm.Width: Commonly is 500 mm.Note: You can customize it according to your requirements.Usually, PVC sound barrier can be applied to various aspects:Commercial sites have sound barriers such as luxury buildings that are near noisy areas.
