Enclosed cargo trailers are widely used in transportation for their ability to offer protection and security for goods. Especially in North America, Europe, South America, and Australia, enclosed cargo trailers are very popular, primarily due to their robust cargo protection features, ensuring that goods are unaffected by weather or external environmental factors during transport. They provide excellent protection for goods in both cold and humid regions.

Choices of materials for enclosed trailer bodies
As the demands of the logistics industry continue to evolve, the optimization and development of enclosed cargo trailers has become a crucial issue in the industry. The choice of body materials directly impacts the trailer’s weight, durability, and transportation efficiency. The TOPOLO-TRUCK new composite material panel offers significant advantages over traditional metal composite panels.

Insulated Foam Core Composite Panels
Foam-core panels are commonly used for their thermal insulation properties, making them suitable for transporting temperature-sensitive goods while maintaining a lightweight structure.

Lightweight Polypropylene Honeycomb Core Panels
These panels are lightweight yet strong, offering a great combination of strength, insulation, and weight reduction. They are an ideal choice for trailers where reducing weight is important without sacrificing structural integrity.

Waterproof Plywood Composite Panels
This is an affordable option; waterproof and flame-retardant plywood combined with fiberglass reinforcement offers excellent strength and durability.
Common Rear Door Designs for Enclosed Trailers
The design of the rear door of an enclosed trailer directly affects the efficiency and safety of loading and unloading goods.

Hinged Wing Doors
Simple design, suitable for loading and unloading small to medium-sized goods. Wing doors can open in a small space, suitable for scenarios requiring quick opening and closing.

Roll-Up Doors
Using a roll-up structure, the entire trailer can be fully opened, suitable for transporting larger items. This type of door is typically used in situations where goods frequently enter and exit.

Ramp Doors
Commonly used for transporting large, heavy goods, such as cars, motorcycles, snowmobiles, etc. Ramp doors allow heavy items to be easily pushed onto the trailer, reducing the difficulty and risk of manual handling.
