PU sandwich panel structure
Cam-lock type PU sandwich panel is connected by cam-lock, it is easy to install, and has advantages of fire resistance, high compressive strength, good sealing, and etc. It is suit for temperature of -50°C to +100°C, and nonperishable.
Taking polyurethane with excellent insulation performance as core material and pre-painted galvanized iron (PPGI/color steel), 304 stainless steel or aluminum as external material, PU sandwich panel can reduce the heat conduction due to difference between internal and external temperature to achieve maximum efficiency of freezing and refrigeration system.
