A foldable warehouse cage is welded from cold-hardened steel, giving high strength and a heavy load. Used in a warehouse, its value shows in two main ways. First, it makes warehouse tidying more orderly. Cages of the same spec, shape, and size each hold a fixed amount of material, so everything sits neatly after storage, and staff stocktake each category easily. Different materials can be layered independently, and partial unloading does not create a mess. Second, it saves warehouse space. When loaded, cages can be stacked high by machine for three-dimensional storage; when idle, the cages fold down to a fraction of their footprint, so empty cages do not fill the warehouse. This is why Xintongnuo recommends that manufacturing and logistics companies choose the foldable version: neat in daily use, compact when stored.
