Dual-driven by policies and technologies, the light wall panel production line industry is advancing towards a new stage of intelligent and low-carbon development.
By 2025, the light wall panel (also known as lightweight partition board) industry in China has witnessed explosive growth under the dual impetus of strengthened green building policies and technological innovation. As a core component of prefabricated buildings, the light wall panel production line, leveraging its advantages of efficiency, environmental friendliness, and customization, is expected to drive the industry's market size to exceed 430 billion yuan. Among this, the composite lightweight wall panel segment will reach 201 billion yuan, becoming a key engine for the transformation of the building industrialization process.
Policy dividends are being released, and market demand is continuously expanding.
The policy orientation has laid a solid foundation for industry development. The Ministry of Housing and Urban-Rural Development's "14th Five-Year Plan for the Construction Industry" clearly stipulates that by 2025, the proportion of prefabricated buildings in new construction should exceed 30%. The construction of "good houses" has further raised the standards for wall sound insulation, environmental protection, and energy efficiency, directly driving a surge in demand for light wall panels. In 2024, the newly started prefabricated construction area across the country reached 850 million square meters, leading to a breakthrough in the application volume of light wall panels at 1.53 billion square meters, with a year-on-year growth of 9.3%.
The market demand shows diversified characteristics. Residential buildings remain the core application field, accounting for 62.4% of the total. Affordable housing and urban renewal projects have become the main sources of demand; public buildings such as hospitals and schools have high requirements for fireproofing, sound insulation, and environmental protection, driving the demand for gypsum-based composite wall panels to rise to 27.6%. Industrial factory buildings prefer high-strength, fast-installation metal-faced sandwich panels. In terms of regional distribution, the East China region leads with a 37.2% market share, and the penetration rates in the Yangtze River Delta and Pearl River Delta economic development regions exceed 30%. The accelerated urbanization process in the central and western regions is giving rise to new growth poles.
Technological innovation leads the way, and production lines are moving towards intelligent and low-carbon.
Intelligent upgrading has become the core competitiveness of the industry. Leading enterprises have launched fully automated production lines, integrating intelligent control throughout the process of batching, mixing, pouring, demolding, and stacking, reducing labor costs by more than 60% and maintaining a product qualification rate of over 99%. Companies such as Beike Building Materials and Sanli Machinery have introduced industrial robots and BIM technology to achieve real-time control of production parameters, increasing the daily production capacity of a single line by 40% compared to traditional processes, and enabling the flexible production of various types of products such as hollow strips (K type), solid strips (S type), and composite strips (F type).
The transition to low-carbonization has achieved remarkable results. Production lines generally use industrial solid wastes such as fly ash, slag, and desulfurization gypsum as raw materials, with the utilization rate of solid waste increasing to over 80%. The "Cai Nong Ning Xin" technology developed by Zhengzhou University has achieved 90% or higher utilization of solid waste, eliminating the need for high-temperature autoclaving processes and reducing energy consumption by 90%. The innovation of environmentally friendly materials has accelerated, with emerging categories such as foamed ceramic wall panels and plant fiber boards expected to account for 9% of the market share, and the demand for A1-level fire-resistant products to reach 45%. This aligns with the requirements of the "dual carbon" goals.
The industrial landscape is optimizing, and full-chain collaborative development is taking place.
The industry's concentration continues to increase, with leading enterprises strengthening their competitive advantages through industrial chain integration. Leading companies such as Beike Building Materials and Kousheng Co., Ltd. have established national production bases, and the market share of the top ten enterprises is expected to increase from 38% to 55%. Regional leaders focus on specific market segments, forming differentiated competitive patterns. The synergy of supply chain is prominent, with upstream raw material enterprises achieving direct supply in their regions, reducing logistics costs by 37%; downstream construction enterprises and equipment manufacturers jointly develop modular mobile production lines, compressing the construction cycle to 90 days.
The export market has steadily expanded, becoming a new growth point. In 2024, the export volume of light wall panels accounted for over 46% of the total, with products gaining international recognition for their high cost-effectiveness and environmental performance, mainly from Southeast Asian and Middle Eastern markets such as Vietnam, Malaysia, and Saudi Arabia. With the advancement of infrastructure projects along the "Belt and Road" route, the proportion of overseas production capacity deployment has increased from 5% to 8%, and the growth potential is promising in the future.
Looking ahead, under the continuous policy support and the promotion of market demand upgrading, the light wall panel production line industry will accelerate its transformation towards "intelligent, efficient, low-carbon, and environmentally friendly, and full-chain collaboration". Industry enterprises need to continuously increase research and development investment, improve the standard system, and solve challenges such as raw material price fluctuations and regional production capacity imbalance, to provide solid support for the high-quality development of the construction industry and the realization of the "carbon neutrality" goal.
