Curtain side trailers have retractable curtains on the sides that allow for efficient side loading and unloading, which is particularly useful in industries such as logistics, construction, and retail distribution. Our curtain-side trailers are engineered for performance, combining strength, durability, and advanced features to meet a variety of transportation needs.
- The sides are made of durable, weatherproof curtains that can be pulled apart for side loading and unloading.
- Cargo is secured with ratchet straps attached to the truck’s internal frame to prevent movement during transport.
- The curtain-side system and body structure are generally lighter than hard-sided trucks, which can improve fuel efficiency.

Trailer Bodies are Made From a Combination of Materials

Curtains
Both sides of the vehicle are made of durable, weatherproof curtains that can be pulled apart for loading and unloading from the side. The curtains are made of PVC coated polyester fabric, which is UV-proof, mildew-proof, frost-proof, anti-static, anti-bacterial and flame-retardant.

Frame
- High-strength Aluminum Alloy: It helps reduce overall weight while maintaining structural integrity.
- Galvanized Steel: It provides strength and durability in harsh weather conditions without rusting, but adds more weight than aluminum.

Roof
- Fiberglass Composite Panels: Fiberglass composite panels for the roof can add insulation and reduce weight.
- Aluminum or Steel Panels: Curtain side truck roofs are typically made from lightweight aluminum or steel, providing structural support and weather protection.

Rear Doors
Usually made of fiberglass composite panels or aluminum, multiple door locking systems are available for installation to ensure security and easy operation.

Flooring
The materials for flooring are rich and varied, and can be selected from marine plywood, aluminum panels, thermoplastic honeycomb panels, etc., depending on the application, and their surfaces are treated with a non-slip coating.

Fixings and Fastening Mechanisms
- Polyester Ratchet Straps: Polyester straps are used to secure cargo inside the truck.
- Steel Ratchet Buckles: The straps are tightened using steel ratchet buckles, which provide a secure fastening and are abrasion resistant.
