Foldable storage cages, also known as butterfly cages, foldable iron frames, logistics turnover iron cages, and express sorting cages, can be used as logistics carts with wheeled feet added. The main body is made by welding low-carbon steel wire of Q235, reinforced with thickened channel steel at the bottom, and treated against rust using galvanizing or electrostatic spraying. They feature butterfly-style folding hinges, allowing the empty cage to be folded up to save storage space. A movable cage door with safety latches is provided on the front, enabling retrieval even when stacked in multiple layers. Sturdy corner supports ensure stable stacking, and the transparent mesh allows easy visual inventorying of goods. Optional accessories such as universal brake wheels, label cards, top covers, and partition boards are available; a wide range of specifications allow customization. With excellent load-bearing capacity, they are suitable for handling by floor cranes and forklifts. Widely used in express sorting, e-commerce cloud warehouses, factory workshops, hardware and auto parts turnover, and cargo storage, they enable unitized storage, sorting, and circular circulation of goods. They are sturdy, resistant to impacts, and can be reused over long periods.
