With the breakthroughs and popularization of high-speed rail technology, the demand for high-speed rail interior panels has become a key driver of market growth. High-speed rail interior panels not only require aesthetics and comfort but also need to meet high standards for flame retardancy and environmental protection, which has enabled enterprises with high technical capabilities in the industry to gain greater development space.
Since 2015, China's rail transit interior panel industry has entered a critical period of transformation and upgrading. As the country attaches increasing importance to environmental protection and energy conservation policies, traditional high-pollution and high-energy-consumption production processes have been gradually phased out. Leading enterprises in the industry have begun to increase R&D investment in environmental protection technologies and launched a series of products that meet international environmental standards. For example, interior panel products adopting environmentally friendly technologies such as water-based paints and low-VOC materials have gradually become mainstream in the market. In addition, the application of intelligent production technologies has significantly improved production efficiency and product quality. The adoption of advanced equipment such as automated production lines and intelligent testing systems has made the production process of interior panels more precise and efficient. According to industry reports, the compound annual growth rate (CAGR) of China's rail transit interior panel market is expected to further increase to approximately 15% during 2020-2025, with the market size expected to exceed 30 billion yuan RMB.
From 2025 onwards, China's rail transit interior panel industry will embrace broader development prospects. With the in-depth advancement of the "Belt and Road" Initiative and the continuous improvement of domestic urban rail transit networks, the demand for rail transit interior panels will continue to grow at a high speed. Especially in the high-speed rail sector, as the technology for high-speed trains with a speed of 350 km/h and above becomes more mature and widely applied, the demand for high-performance and high-standard interior panels will become even stronger. At the same time, the construction of urban rail transit systems such as metro and light rail will also drive the continuous expansion of the interior panel market. According to predictive plans, by 2030, the market size of China's rail transit interior panels is expected to reach over 40 billion yuan RMB. During this phase, enterprises in the industry will further enhance their product competitiveness through technological innovation and cross-sector cooperation. For instance, they may collaborate with enterprises in fields such as new materials and new energy to develop more environmentally friendly and efficient interior panel products; utilize technologies like big data and artificial intelligence to optimize production processes and product designs; and actively expand overseas markets.
In terms of technological development directions, "greenization", "intelligentization", and "personalization" will become the main trends of China's rail transit interior panel industry in the next few years. In terms of greenization: the industry will continue to promote the R&D and application of environmentally friendly materials; in terms of intelligentization: more investment will be made in intelligent manufacturing technologies; in terms of personalization: interior panel products will be custom-designed according to the needs of different lines and vehicle models. In addition, "lightweighting" will also become an important development direction; by adopting new materials and structural designs to reduce product weight, energy consumption can be lowered and operational efficiency improved. "Health-oriented development" will also become a key direction for future development: by using antibacterial and mildew-proof materials and technologies, the air quality inside vehicles will be improved to provide passengers with a healthier and more comfortable travel environment.
In terms of materials, rail transit interior panels are mainly divided into three categories: metal panels, composite materials, and wooden panels. As an emerging interior decoration material, composite materials have gradually increased their market share in recent years. Composite materials are mainly composed of glass fiber, polyurethane, vinyl, and other materials, and have the advantages of being lightweight, flame-retardant, and moisture-proof. They are increasingly widely used in high-speed rail carriages and some new-type metro vehicles. According to market data, the share of composite materials was approximately 8% in 2024, and is expected to grow to 12% by 2030. This growth is mainly driven by the continuous maturity of composite material technology and the gradual reduction of costs.
From the perspective of application scenarios, rail transit interior panels are mainly used in high-speed rail carriages, metro carriages, light rail vehicles, and station halls and platforms. High-speed rail carriages are one of the application scenarios with the largest demand for interior panels, as their internal decoration has high requirements, and strict standards are imposed on the durability and aesthetics of materials. According to statistics, the proportion of interior panels for high-speed rail carriages was approximately 40% in 2024, and is expected to rise to 48% by 2030. The demand for interior decoration in metro carriages and light rail vehicles is also relatively large; their market shares were 30% and 15% respectively in 2024, and are expected to grow to 35% and 18% by 2030. For public areas such as station halls and platforms, metal panels and composite materials are the main interior decoration materials; their market share was approximately 15% in 2024, and is expected to remain at this level by 2030.
From the perspective of segmented markets, the high-speed rail interior panel market is one of the fastest-growing segments. In recent years, China's high-speed rail technology has made continuous breakthroughs, and the performance requirements for interior panels have been increasing. For example, high-speed trains have stricter requirements for the flame retardant grade, sound insulation performance, and lightweighting of materials, which has driven the demand for high-performance composite materials and environmentally friendly interior panels. It is expected that by 2030, the market size of high-speed rail interior panels will reach approximately 12 billion yuan RMB, accounting for 30% of the overall market.
With the continuous improvement of rail transit networks and the in-depth advancement of technological innovation, China's rail transit interior panel industry will move towards a new stage of high-quality development featuring "safety and reliability, green and low-carbon, intelligence and comfort", and provide a "Chinese solution" for the upgrading of global rail transit equipment.
