Core Viewpoint - The sound barrier industry in China is experiencing significant growth driven by urbanization, increased demand in transportation and construction sectors, and heightened public awareness of environmental issues. The production and demand for sound barriers are expected to rise steadily, with market size projected to reach 115.36 billion yuan by 2025 [1][5]. Industry Definition and Classification - Sound barriers are measures used to block direct sound between a source and a receiving point. They can be classified based on usage (traffic, equipment noise reduction, industrial), material (metal, concrete, PC, fiberglass), and purpose (railway, highway, urban landscape, residential noise reduction) [2][3]. Industry Development Status - The development of sound barriers in China began in the 1970s. The industry faces challenges due to high customization requirements and varying specifications. The production is expected to grow from 4,828 million square meters in 2024 to 5,358 million square meters in 2025, with demand following a similar upward trend [3][5]. Market Size and Growth - The market size for sound barriers in China is projected to reach 105.23 billion yuan in 2024, with significant contributions from the transportation sector (75.4 billion yuan) and industrial production (16.48 billion yuan). By 2025, the market size is expected to grow to 115.36 billion yuan [5][18]. Industry Chain - The sound barrier industry chain includes upstream raw material supply (metal materials, PC boards, glass), midstream product manufacturing, and downstream application in construction, industrial production, and urban transportation. The collaboration across these segments is crucial for industry growth [7][18]. Competitive Landscape - The sound barrier market in China is characterized by a large number of manufacturers with relatively weak overall strength. Key players include state-owned enterprises, private companies, and foreign firms, with notable participants such as Hengxiang Technology, Tibet Zhongchi Group, and Changzhou Tiansheng New Materials [9][12]. Key Companies - **Tiansheng New Materials**: Focuses on high polymer material processing, with significant patents in sound barrier products. The company reported a revenue of 531.2 million yuan in 2024 [12][13]. - **Hengxiang Technology**: Provides integrated solutions for traffic noise control and has a diverse product range including sound barriers and engineering rubber products [15][18]. Industry Development Trends - The sound barrier industry is expected to benefit from China's stable economic growth, accelerated urbanization, and advancements in technology and materials. Environmental sustainability will also play a crucial role in shaping the market [18][20].
