Handmade PU Sandwich Panel

The Handmade Polyurethane (PU) Sandwich Panel features a rigid polyurethane foam core sandwiched between color-coated steel or stainless steel sheets, with added internal supports for enhanced strength. Produced using a manual lamination technique, this panel offers high structural integrity and is particularly suitable for cleanroom projects, industrial buildings, and cold chain engineering. The PU core provides one of the most efficient insulation performances among common core materials.

The panel delivers excellent thermal insulation, which is critical for maintaining stable environmental conditions in controlled spaces. Its high strength-to-weight ratio and excellent dimensional stability make it suitable for large-span walls and ceilings. The flat, seamless surface is easy to sanitize and maintain, while the manual production process allows for non-standard sizes and customized structural adjustments to meet unique installation challenges. Secure jointing is achieved via tongue-and-groove or middle aluminum profile systems, ensuring consistent alignment across large surface areas.
