Storage cages are also called warehouse cages and butterfly cages. They are a very important type of logistics container in warehousing and transportation. They have the advantages of fixed storage capacity, neat stacking, clear storage, and easy inventory counting. At the same time, it also improves the effective utilization of storage space. . The storage cage can be folded freely, and can be folded and stored when not in use, saving warehouse space. The main components of the storage cage are divided into mesh manufacturing and chassis manufacturing. The mesh is made of raw material Q235 or Q195 high-speed wire through drawing processing into thin wires with a wire diameter of 5.8 or 6.2 or more, and then cut into various lengths, and the mesh is touched by a welding machine to produce semi-finished mesh. Most of the meshes are galvanized, but also sprayed. The rust-proof galvanizing is better than sprayed. The wire diameter is an important parameter of the load. The chassis is processed by the raw material plate through a bending machine. The plates are usually 1.8 and 2.5, then cut and manually welded into channel steel. Chassis is an important parameter of load bearing. There are two types of bottom mesh and bottom channel steel welding. One is manual welding, which cannot guarantee that each contact point is welded; the other is full welding technology, where each contact point of the channel steel and the mesh is passed through a machine welder. The bearing capacity is stronger. Finally, the mesh and the chassis are assembled through the spring and the rebate. The design of the foldable storage cage is to provide convenience for access at any time. During stacking storage, the small door can be opened to deposit or take out items at any time, eliminating the trouble of turning over the warehouse. Moreover, it is stored after folding, which greatly saves space.
