Product Introduction
Polyurethane O-slot cold storage panels are specialized high-performance envelope materials designed for cold chain logistics and low-temperature warehousing projects. Different from regular roof panels, these products are optimized with an O-slot structural design and use rigid polyurethane foam with a closed-cell rate of over 95% as the core material, compounded with high-quality corrosion-resistant surface plates via automated production lines. The panels integrate superior low-temperature insulation, enhanced sealing waterproofing, lightweight high-strength and cold-resistant durability into a single solution. With an ultra-low thermal conductivity of 0.022 W/(m·K), they can stably maintain the internal temperature of cold storage facilities from -25℃ to 15℃, effectively preventing cold loss and condensation. They are the first-choice roofing materials for high-standard cold storage, cold chain logistics centers and low-temperature processing workshops.
Product Advantage
The core material of the O-slot cold storage panels is formulated for low-temperature environments, with a thermal conductivity as low as 0.022 W/(m·K). Its insulation performance is 3 to 5 times that of traditional cold storage insulation materials. This excellent insulation capability can stably maintain the low-temperature environment inside the warehouse, minimize cold energy loss and prevent condensation on the panel surface. It ensures the quality and safety of refrigerated goods, significantly reducing the energy consumption of refrigeration equipment in cold storage facilities.
The exclusive O-slot lock seam lap joint system is the core structural advantage of these panels. Compared with regular lap joint methods, the O-slot design enhances the sealing performance of the roofing system, effectively preventing cold air leakage and external moisture intrusion. Meanwhile, the structural design simplifies the installation process, shortens the construction period by 30% compared with traditional cold storage roof materials, and is especially suitable for the rapid construction needs of large-scale cold chain logistics projects.
Manufactured with advanced composite molding technology, the panels have a compressive strength of over 150kPa, with excellent wind resistance and load-bearing performance. They can withstand the low-temperature contraction and expansion stress of cold storage environments, and support direct walking for maintenance operations. With a density of 40-45kg/m³, the panels are over 90% lighter than concrete roofs, reducing the structural load of cold storage buildings and lowering foundation construction costs. The 55% aluminum-zinc alloy surface layer has a corrosion resistance life of over 25 years, adapting to the humid and low-temperature working conditions of cold storage.
The core material of the panels meets the B1-level flame-retardant standard, and A-level fireproof composite core material is optional for projects with strict fire requirements. The production process uses cyclopentane-based fluorine-free foaming technology, which does not contain harmful fluorine-containing substances. The product has obtained China Green Building Materials Product Certification, complying with the environmental and hygiene standards of the food and medicine industries. It is suitable for cold storage facilities that store food, pharmaceuticals and other high-standard products.

FAQ
Yes. The high closed-cell rate polyurethane core material and O-slot sealing design can effectively isolate the internal and external temperature difference. They prevent water vapor from condensing on the panel surface, maintaining a dry environment inside the cold storage and avoiding damage to goods and equipment caused by condensation.
The O-slot design is optimized for installation convenience. It only requires basic training for construction teams to operate, and the installation speed is faster than regular cold storage panels. We can also provide detailed installation guidelines to ensure the construction quality of the roofing system.
No. The panels integrate insulation and moisture-proof functions. The closed-cell structure of the polyurethane core material and the sealed O-slot lap joint system can fully block external moisture from entering the cold storage, eliminating the need for additional moisture-proof layers.
Absolutely. The 15-year quality warranty for the roofing system fully covers the cold storage environment. It includes the core performance indicators of waterproofing, insulation and structural stability under low-temperature and high-humidity conditions, providing long-term guarantee for cold chain projects.
