PVC Foam Sandwich Panels for Trailer & Truck Bodies
PVC(Polyvinyl Chloride) foam core composite panels are a new type of truck and trailer body material, primarily used for constructing high-performance cargo boxes or camper bodies.
PVC Foam – Balanced Performance
PVC foam is a rigid closed-cell foam material. Compared to other foams (PET, EPP, EPS, XPS, etc.), it has many advantages such as high strength, light weight, corrosion resistance, high temperature resistance, and water resistance.

Structure of PVC Foam Core Sandwich Panels
Standard Structure
A typical skin-core-skin sandwich structure is simple in design, easy to process, and suitable for most cargo boxes or camper vehicle bodies.
Reinforced Structure
Structural strength is improved by adding energy-absorbing felt layers and internal embedded parts. Suitable for vehicle bodies requiring high structural strength.
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.
