From CKD Kits to Complete Van Bodies
Breaking away from the complicated processes of traditional box van body assembly, TOPOLO-TRUCK adopts a standardized modular body structure design. Kits can be quickly connected and assembled without complex manufacturing procedures or highly specialized installation requirements. This greatly simplifies the complete body assembly process, making it ideal for large-scale production and vehicle conversions. The modular system effectively improves production efficiency, shortens delivery lead times, and helps vehicle manufacturers and body builders reduce labor costs while increasing overall operational efficiency.
No Size Limitations for Van Body Construction
Whether for light-duty, medium-duty, or heavy-duty van bodies, thermoplastic honeycomb composite panels can be used for construction.
| Duty Type | Length Range (m) | Width Range (mm) | Height Range (mm) |
|---|---|---|---|
| Light Duty | 2.8 – 5.2 | 1810 | 1900 |
| Medium Duty | 5.2 – 6.7 | 1810 – 1900 | 1900 – 1950 |
| Heavy Duty | 6.7 – 12 | 1810 – 2500 | 1950 – 2700 |
Structure of The New Fiberglass Honeycomb Panel
The new thermoplastic fiberglass honeycomb panel is manufactured using CFRT (Continuous Fiber Reinforced Thermoplastic) skins combined with a polypropylene honeycomb core.
- Unlike conventional “skin-core-skin” fixed structures, this advanced system allows different CFRT layer configurations, fiber orientations, and honeycomb core densities to be selected according to actual vehicle body requirements, achieving the ideal balance between structural performance and lightweight design.
- Compared with traditional thermoset FRP honeycomb panels bonded by adhesives, this thermoplastic fiberglass honeycomb panel adopts a thermal lamination process for integrated bonding, effectively avoiding common delamination and cracking issues during long-term use while greatly improving structural reliability and service life.
Different Honeycomb Panels for Different Body Sections

- Smooth, aesthetically pleasing, and with excellent sealing.
Key Advantages of Selecting Thermoplastic Honeycomb Composite Materials
☑ Extreme Lightweight Design for Enhanced Operational Efficiency
The biomimetic honeycomb structure inherently possesses lightweight properties. A standard 30mm thick honeycomb panel weighs no more than 5.0 kg/m². According to extensive field data from the TOPOLO-TRUCK laboratory, under the same thickness conditions, thermoplastic fiberglass honeycomb panels weigh only 1/10 to 1/6 of steel hollow panels, 1/4 to 1/3 of aluminum hollow panels, 1/2 of foam core panels, and 1/5 to 1/3 of plywood. This significant reduction in vehicle weight effectively increases the vehicle’s rated cargo volume and load capacity, while simultaneously reducing fuel consumption and extending driving range. The widespread adoption of honeycomb composite structure in van bodies has already helped major logistics and freight companies reduce costs and increase efficiency, creating considerable economic value.
☑ High Structural Stability, Resistant to Deformation
Lightweight design without sacrificing structural strength or service life. Utilizing advanced thermoplastic lamination technology and TOPOLO-TRUCK’s exclusive patented structural design, the industry pain point of large-size honeycomb panels being prone to bending and deformation is completely overcome. Even in large box-type vans with bodies ranging from 9m to 12m, overall rigidity and stability remain excellent. Verified by end-users under actual road conditions, the vehicle has undergone long-term operation on rugged mountainous areas and bumpy roads without any loosening, deformation, or abnormal noise.
☑ Long-Term Durability
The panel formula incorporates specialized anti-aging additives and functional modifiers, significantly enhancing its weather resistance, corrosion resistance, and anti-corrosion properties. It can withstand the erosion of complex media such as moisture, acids, alkalis, and salt spray, ensuring safe transportation of everyday goods, general dry goods, as well as special cargo such as chemical raw materials and corrosive materials. Suitable for all-weather, multi-scenario operations, it is resistant to aging and damage over long-term use.
☑ Aesthetic Appearance Comparable to Gel-Coat FRP
The surface treatment of thermoplastic fiberglass honeycomb panels is comparable to traditional gelcoat FRP materials, and can be finished with various textures such as high-gloss, matte, and frosted. A rich and diverse range of colors are available, including classic white and black, and support for custom color matching based on the full range of RAL industrial color cards. The overall vehicle body boasts a high-end look and premium feel, balancing practicality and aesthetics.
