Founded in 2003 and strategically located in Changzhou, Jiangsu Province, the company operates from a facility situated approximately 140 kilometers from Shanghai Port. Yijing positions itself as a professional large-scale manufacturer covering cold room design, freezer room production, and refrigeration systems integration. Core business areas include cold storage rooms, polyurethane sandwich panels, cold room doors, and related accessories for industrial, pharmaceutical, and food processing applications.
The High Efficiency PU Cold Room Panel is constructed using advanced polyurethane foaming technology combined with precision metal sheet folding machinery to ensure uniform foam density and consistent manufacturing quality across each panel. This product enables modular cold storage construction with joinery facilitated by quick-action eccentric mechanisms, allowing for rapid assembly, straightforward disassembly, and future capacity enlargement without extensive reconstruction. When integrated with high-density polyurethane insulation panels, the system provides excellent thermal insulation performance, effectively blocks external heat invasion, reduces cold energy loss, maintains stable internal temperatures, and significantly lowers long-term operating energy consumption in freezing and refrigeration systems.
The global cold storage insulated panels market is undergoing rapid expansion. According to QYResearch, the worldwide market for cold storage insulated panels was valued at approximately USD 2.61 billion in 2025, with Asia-Pacific representing the largest regional market with roughly 43 percent of global share. As part of the broader sandwich panel ecosystem, global sandwich panel market size reached USD 11.57 billion in 2025 and is projected to expand to USD 24.12 billion by 2034. The insulated sandwich panel market, a key proxy for polyurethane cold room panel demand, was valued at USD 8.22 billion in 2025, with year-on-year growth of 7.9 percent in 2026. Within the specific cold storage metal panel segment, Global Info Research reported a value of USD 934 million in 2025, with polyurethane panels representing the dominant product type [10†L2-L4].
Cold storage construction activity is accelerating substantially. According to 360iResearch, the market was valued at USD 18.44 billion in 2025 and is projected to reach USD 60.91 billion by 2032, driven by increasing demand for processed food storage, growth of pharmaceutical cold supply chains, and the global expansion of temperature-sensitive e-commerce logistics networks. The Business Research Company confirmed the cold storage construction market size grew from USD 17.04 billion in 2025 to USD 19.77 billion in 2026, representing a robust 16.0 percent CAGR. A key driver is the surge in processed food consumption, which requires extensive refrigerated storage and distribution capabilities throughout the supply chain.
Yijing maintains an annual production capacity of 5 million square meters of cold room panels and currently exports its cold storage solutions to the United States, France, Australia, Italy, and more than 20 other countries and regions. The company attained ISO9001:2008 quality management certification in 2012 and continues to pursue advanced core materials and edge jointing innovations to reduce thermal bridging, improve long-term energy efficiency, and maintain compatibility with strict international food safety and pharmaceutical storage standards.
The High Efficiency PU Cold Room Panel is now available through Yijing’s global distribution network for industrial contractors, cold chain developers, food processing facility operators, and pharmaceutical storage providers requiring high-performance, rapidly deployable modular cold storage insulation systems. Yijing will initiate the second phase of its development strategy while focusing on research, product innovation, and international market expansion for the coming years.
