Trailer Cage

A trailer cage is an add-on steel framework bolted onto the sides and rear of a flatbed or utility trailer to confine and secure loose or bulky cargo, effectively forming high walls to prevent spillage and enhance load versatility. These structures typically consist of side panels, a front panel, and a hinged or swing rear gate with locking provisions, and are built from structural hollow sections or mesh grids (e.g., 40 × 40 mm RHS frames with 100 × 50 × 4 mm mesh) that offer clear visibility while maintaining strength. Cage kits are often hot-dip galvanized to resist corrosion and rugged enough for regular commercial use, and can be installed or removed in minutes to adapt to different haul scenarios.
