High-Quality Foam Core
☑ Low thermal conductivity: ensures excellent thermal insulation properties.
☑ Low water absorption: Effectively prevents performance degradation caused by moisture, maintaining panel stability.
☑ Low deformation: Resists collapse and cracking, maintaining flatness over long-term use.
Available Foam Core

High-Performance GRP/FRP Facing
☑ Smooth Surface: Easy to clean and maintain.
☑ Various Color Options: Meet the design needs of various off-road trailers.
☑ Weather-Resistant and UV-Resistant: Ensures color retention and resistance to fading and chalking even after extended outdoor use.
☑ Durable: Provides excellent impact and abrasion resistance.

Superior Bonding Technology
The use of high-viscosity waterproof adhesive combined with vacuum negative pressure composite technology ensures a close bond between the foam core and the FRP skin, effectively eliminating common problems such as delamination, warping, and bulging, and significantly improving the overall life and stability of the composite panel.

Structural Reinforcement
By integrating a lightweight internal “skeleton” (wood, metal, composite) within the composite panels, structural strength is greatly improved while maintaining a lightweight appearance, making it an ideal choice for weight reduction and enhancement in off-road trailers.

Excellent Post-Processing Capabilities
TOPOLOGROUP is equipped with advanced high-precision CNC machining centers, capable of integrated cutting and processing according to customer design drawings. This ensures that each composite panel accurately replicates the design, reduces secondary processing errors, and improves assembly efficiency.
Accessories Support
TOPOLOGROUP not only provides high-performance composite panels, but also provides customers with comprehensive accessories support to ensure the coordination and unity of vehicle body structure and overall performance.

Connecting Profiles
We customize panel connecting profiles based on customer design requirements, offering a full-process service from design to production, including mold-making and production of various aluminum extrusion profiles.

Trailer Chassis
TOPOLOGROUP offers a wide range of trailer chassis specifications, including fully assembled chassis, CKD (Completely Knocked Down) or SKD (Semi-Knocked Down) chassis, tailored to customer needs, for convenient local assembly and installation. The chassis is constructed of high-strength steel, ensuring durability and safety over the long term.
