Foldable cages deliver real gains. They use quality steel, cold-work-hardened before welding, for high strength that carries heavy material. In a warehouse, the most immediate payoff is order. First, the storeroom gets tidy. Uniform specs, shapes, and sizes, and a fixed load per cage, mean a neat, uniform layout that lets warehouse staff stocktake fast. Different materials sit in different cages with clear layers — no more rummaging around. Second, space saving. A stacker lifts cages three-dimensionally to claim height; idle cages fold flat and stack together, taking almost no floor space. On return trips, one truck carries many folded cages, cutting back-haul freight.
