Best Selling Cargo Transport Dry Van Type Box 60 Tons 40ft Open Wing Van Box Semi Trailer

A curtain-sided semi-trailer, also known as a curtain-sider, is a versatile freight transport vehicle characterized by its flexible side curtains and reinforced aluminum framework. The primary structure features durable polyester or PVC-coated fabric curtains tensioned across an extruded aluminum roof bow system, providing weather-resistant protection while enabling full lateral access to cargo.

This design combines the security of rigid walls with the operational flexibility of open-platform trailers, allowing rapid side-loading through complete curtain retraction. The lightweight aluminum superstructure (typically 6,500-7,500 kg tare weight) maximizes payload capacity while maintaining aerodynamic efficiency.
