PU Foam Sandwich Panels for Trailer & Truck Bodies
To ensure excellent insulation performance for refrigerated truck and trailer bodies, selecting the right insulation material is crucial. Among various materials, composite panels with PU (Polyurethane) foam as the core material are the ideal choice.
Polyurethane Foam – Thermal Insulation & Lightweight
PU foam has an extremely low thermal conductivity, effectively blocking external heat and ensuring a stable internal temperature, thereby improving energy efficiency and reducing energy loss. Additionally, the lightweight and high-strength characteristics of PU foam allow for effective weight control of the vehicle body without compromising structural strength and durability. Its moisture resistance also ensures that refrigerated trucks maintain insulation performance even in humid environments, adapting to harsh transportation conditions. Therefore, using PU foam composite panels as insulation material for refrigerated trucks and trailers significantly enhances the efficiency and reliability of cold chain transportation.

Skin Materials
FRP/GRP Sheets
FRP sheets are an ideal material for truck and trailer bodies due to their lightweight, high strength, corrosion resistance, good thermal insulation, and weather resistance, making them widely used in various transportation vehicles such as refrigerated trucks and dry cargo trucks. They not only effectively reduce vehicle weight and improve transportation efficiency, but also possess UV resistance, impact resistance, and low maintenance costs, ensuring long-term vehicle stability in harsh environments. Furthermore, the excellent mechanical properties and aesthetically pleasing design of FRP sheets make them an essential component of various commercial vehicles.
CFRT Sheets
CFRT sheets, as a new type of thermoplastic FRP material, offer highly reliable vehicle body solutions thanks to their advantages such as high strength, lightweight, high temperature resistance, impact resistance, and corrosion resistance. Whether for refrigerated trucks, dry cargo trucks, or special-purpose vehicles, CFRT sheets can improve vehicle safety, durability, and transportation efficiency, while reducing maintenance costs and extending vehicle lifespan.
Aluminum Alloy Sheets
Using aluminum alloy sheets for truck and trailer bodies provides numerous advantages, including a lightweight structure, high strength-to-weight ratio, corrosion resistance, and low maintenance. These benefits lead to improved fuel efficiency, increased payload capacity, and lower operational costs. Additionally, aluminum’s recyclability and ability to withstand extreme conditions make it an environmentally friendly and durable option for commercial vehicle manufacturers.
Coated Steel Sheets
Coated steel sheets offer a highly durable, cost-effective, and versatile body solution. They combine high strength, corrosion resistance, and aesthetic appeal, while providing long-term protection against environmental and mechanical stresses.
