The foldable wire mesh cage, also called a storage cage, is welded from strong wire with bottom U-shape weld reinforcement. It is strong and load-heavy; ratings run 0.8 to 2.0 tonnes by model, and it stacks four layers for three-dimensional storage. It is widely used by manufacturers and large warehouse supermarkets to temporarily store, transport, sort, and hold raw materials, semi-finished goods, and finished goods. There are many specs, from 200 kg to 2000 kg, foldable and stackable. High-quality steel wire is spot- and press-welded, with a bottom U-channel reinforcement. As a special packaging form it resembles a pallet, but it both stacks and stores three-dimensionally and doubles as a logistics turnover box. The foldable structure eases loading, turnover, and storage, keeping units neat and unit-managed; idle cages fold flat to save space. The galvanized surface looks good, resists oxidation, lasts long, stays hygienic, and keeps turnover, storage, and recycling pollution-free.
