Product Description

Product Description

    3/4 Axle High Quality Curtain Side Semi Trailer for Cargo Transport

    Our Curtain Side Semi Trailer is specially designed for efficient loading, unloading, and safe transportation. It combines the strength of a container with the flexibility of a box trailer. Equipped with high-tensile PVC curtain sides and sliding mechanisms, it allows fast side access to cargo, significantly reducing loading time and operational costs. This model is widely used in logistics, distribution, and industrial transportation across Europe, Southeast Asia, Africa, and South America.
    The Curtain Side Semi Trailer offers a perfect balance between protection and accessibility. Unlike traditional box trailers, this model allows for side, rear, and even top loading, making it ideal for palletized goods, long structural items, or mixed cargo. Its curtain mechanism is reinforced with tensioning straps and lock-in buckles to keep goods secure even in harsh weather or rough road conditions.
    The strong steel frame and anti-corrosion coating ensure long-term durability even in humid or coastal environments. The rear doors are made of galvanized steel or aluminum alloy and equipped with robust lock systems to guarantee cargo safety
