Warehouse cages are welded from cold-hardened steel, giving high strength and a large load capacity. They can be stacked four layers high for three-dimensional storage. Depending on the model and specification, each cage carries 0.8T to 2.0T. The foldable structure makes loading, turnover, and storage easy; cages sit neatly and support fixed-position, unitized storage management. Empty warehouse cages fold flat when not in use to save space. The galvanized surface looks clean, resists oxidation, and lasts a long time. It stays hygienic, and turnover, storage, and recycling do not pollute the environment. Forklifts, cranes, overhead traveling cranes, lifts, trolleys, and hand pallet trucks can load, move, and stack them, saving time and labor. The cage door opens, so materials can be retrieved without unpacking the whole stack. Nanjing Tongnuo Storage Equipment Manufacturing Co., Ltd. is a manufacturer and supplier of warehouse cages.
