The ramp door is a unique trailer design. It is a ramp when loading and unloading goods, and a rear door when the trailer is driving. After the trailer is equipped with a ramp door, it is very convenient to transport large items such as cars, motorcycles, bicycles, large furniture, industrial equipment, etc.
At present, most cargo trailer ramp doors are made of wood or metal plates. Wooden ramp doors are light but not durable; steel ramp doors are very strong and durable, and can bear the weight of heavy goods, but they are relatively bulky and have poor operability; aluminum alloy materials are lighter than steel, and also have good strength and corrosion resistance, but their prices are higher.
Composite trailer ramp doors developed by TOPOLO reduces weight, increases structural strength, is easier to operate, and is economical. It is favored by many international cargo trailer brands.

- Strong and durable: Waterproof and chemical-resistant, long-term exposure to the outdoors will not affect its structural strength.
- Anti-slip: The surface friction resistance is large, and it can be stable and non-slip even in rain, snow, frost and other weather conditions.
Materials and Performance
The trailer ramp door is composed of composite panels, metal frames, corner profiles, etc. The structure is simple and reasonable, and each material gives full play to its performance advantages.
External composite panel: 15mm FRP skin PET foam sandwich panel. The appearance is flat and smooth.
Frame: It is welded from high-strength galvanized steel pipes and sprayed with anti-corrosion paint, serving as the “skeleton” of the ramp door to provide the main structural support.
Internal composite panel: 15mm anti-slip CFRT skin honeycomb sandwich panel, with dense anti-slip texture on the surface, and outstanding anti-slip effect. Ensure the stability of goods and personnel when operating on the ramp.
Edge profile: It is extruded from 6061 aluminum and treated with anti-corrosion coating, with a unique “T” cross-sectional structure.
