Storage cages (also known as folding cages or butterfly cages) are collapsible logistics containers made of high-strength steel through cold-rolling hardening and welding. They can be used for transportation, handling, loading and unloading, storage and safekeeping, etc., in conjunction with forklifts, lifts, cranes, and other equipment. With uniform specifications and fixed capacity, they are easy to count and are widely used in manufacturing, e-commerce logistics, cold storage, and the pharmaceutical industry, supporting cargo classification, turnover, and automated management.
