Cold Room Structure

Modular cold storage is assembled using the insulation panels, cold storage door and on-demand configured bearing chassis. Insulation panel uses rigid polyurethane with good heat insulation performance as the core material, uses colored steel plate, stainless steel plate, or pattern aluminum plate as panels, and is compounded by overall foaming. It has a low bibulous rate, high strength, good insulation performance, is lightweight, and is easy to install. According to the use of different parts, it is divided into three types: floor panel, wall panel, and coping panel. Physical performance indicators of the insulation panel are shown in the table below:
