By form, common warehouse cages include metal cages, foldable cages, rack cages, turnover cages, mobile cages, export cages, supermarket cages, and in-plant cages. They are widely used to store raw materials, semi-finished goods, and finished products for storage, sorting, transport, and turnover. They stack three-dimensionally for loading and unloading, double as logistics turnover containers, and even serve as sales containers in supermarkets. From raw-material inbound to finished-goods outbound, they appear at nearly every logistics step — especially in large warehouse-style supermarkets and manufacturing. Xintongnuo's warehouse cages stand out in several ways. Specifications are uniform and capacity fixed, so stocktakes are quick. They are welded from quality steel with a strong load capacity, handling a wide range of goods. Use is flexible: as a standalone storage container, paired with a forklift for turnover, or pushed around once wheels are added. Stacking is strong — up to four or five layers when stable, enabling three-dimensional storage. Whether stacked or not, the half-side mesh door opens for easy picking. The core is the foldable structure. Empty cages fold flat and stack together, saving warehouse space and back-haul freight. With careful material selection they resist corrosion, aging, and deformation under normal use, often lasting ten years or more.
