PU Sandwich Panel

The Polyurethane Sandwich Panel combines a color-coated steel surface with a rigid polyurethane (PU) core, offering stable thermal insulation and reliable structural performance. The continuous production process ensures strong adhesion between the steel sheets and the core material, preventing delamination over time. With a low thermal conductivity, the PU core effectively reduces heat transfer, helping maintain stable indoor temperatures while lowering energy consumption. The tongue-and-groove joint system simplifies installation, reduces seam treatment work, and creates a clean, flat wall surface suitable for hygiene-controlled environments. This product is designed for projects that require efficient installation without sacrificing long-term building performance.

Our factory brings 24 years of industry experience to the production of PU sandwich panels, supported by an in-house R&D team and a 5,000㎡ production base. We maintain strict quality control throughout the manufacturing process, from raw material sourcing to finished product inspection. While we do not offer OEM/ODM services, our mature product line is fully adaptable to a wide range of project specifications. We use high-quality color-coated steel with thickness options from 0.35mm to 0.5mm, paired with a rigid PU foam core that delivers consistent density and insulation performance. Every production batch is monitored to ensure compliance with confirmed order requirements, giving buyers clear visibility into product quality before shipment.

To meet varying project needs, the panel thickness is available in 50mm, 75mm, and 100mm, with a standard width of 1150mm and length customized to order. Buyers can choose from multiple steel sheet thicknesses and surface finishes, including color-coated steel or stainless steel options. Whether for temperature-controlled facilities or general industrial enclosures, we help clients select the right configuration for their application. Production typically takes approximately 10 working days for standard orders, with real-time progress updates available upon request. From specification confirmation to packaging and loading, we support clear communication to help buyers coordinate with their project timelines.

With its balanced performance in insulation, strength, and surface hygiene, the polyurethane sandwich panel is widely used in food processing facilities, biopharmaceutical plants, electronics workshops, laboratories, medical cleanrooms, cold storage, industrial factories, warehouses, logistics centers, and commercial building envelopes. The panel meets the wall and partition requirements of these environments through stable core performance, ease of cleaning, and compatibility with standard cleanroom construction systems.

Quality control begins with the selection of raw materials and continues through each production stage, with final inspection carried out before dispatch. Panels are properly packaged to prevent damage during transit, and loading is coordinated based on order quantity and delivery schedule. We provide timely manufacturing status updates to assist with project planning. While we do not offer design or installation services, our team can provide specification guidance based on the intended application, helping buyers choose the most suitable material configuration. Production timelines are confirmed upon order placement and adjusted according to quantity, ensuring reliable delivery for both small-scale and large-scale projects.
