PC Panel Noise Barriers Upgrade Urban Traffic, Reducing Viaduct Noise by 35 Decibels

     Urban renewal and traffic noise reduction projects are fully promoted in 2026. High-performance PC panel noise barriers have become the preferred material for noise reduction projects of viaducts, expressways and light rails. Represented by Shanghai Yan'an Road Viaduct and Shenzhen Binhe Avenue, the new generation of multi-layer composite PC sound insulation panels have three core advantages: 35 decibels noise reduction, transparent and beautiful appearance, and 20-year aging resistance, reshaping the urban traffic landscape.

     Traditional metal noise barriers are easy to rust, poor in light transmission and bring visual depression; glass noise barriers have problems such as fragility, excessive self-weight and potential installation safety hazards. The PC noise barrier adopts a design of solid PC sheet, hollow structure and composite sound-absorbing cotton, with a light transmittance of over 70%, ensuring a transparent driving vision without depression. Its impact resistance is 250 times that of ordinary glass, and it will not splash and break when hit by hail or traffic accidents, with an extremely high safety factor. It is UV-resistant and aging-resistant, never turning yellow or deforming after 20 years of outdoor use with no maintenance required.

      After replacing with PC noise barriers on Shanghai Yan'an Road Viaduct, the noise of surrounding residential areas dropped from 75 decibels to below 40 decibels, meeting the national residential area noise standard. Shenzhen Binhe Avenue adopts colored PC panels matched with lighting design, forming a popular urban landscape at night. In 2026, more than 20 cities across the country have launched the replacement and renovation plan of PC noise barriers, with a market scale exceeding 5 billion yuan.
