High-Quality Insulated Composite Panels

Our refrigerated truck body panels are mainly made of extruded polystyrene (XPS) and polyurethane (PU) sandwich panels, covered with fiberglass reinforced plastic (FRP) skins. Both the insulation core and the FRP surface layer can be customized in terms of thickness and type.

In addition, we can provide various internal reinforcement structures according to customer requirements, ensuring the panels meet the needs of different applications and usage scenarios. These high-quality insulated panels are also widely used in the manufacturing of compact cold chain solutions, such as the freezer box for pickup truck, delivering excellent thermal efficiency and durability.

By choosing TS Brothers composite panels, customers can build reliable refrigerated bodies or a freezer box for pickup truck with superior insulation, lightweight strength, and long-lasting performance.
