Our refrigerated truck body features advanced construction with new type FRP outer skin for roof, walls, and doors. The sandwich panel construction combines a middle layer of fluorine-free polyurethane foam or extruded polystyrene foam (75-150mm thick) with high-strength adhesive and screw fixation to a steel frame, delivering exceptional thermal insulation and mechanical strength.
