Shelf shelves can be divided into the following categories according to load-bearing capacity and usage scenarios:
Light-duty shelf shelves: This type of shelf is usually made of cold-rolled steel sheets, which are made by bending, forming, welding and reinforcement. It adopts a plug-in combination structure, does not require connecting bolts, and the layer height can be freely adjusted according to demand. The load-bearing capacity of each layer of the light-duty shelf is between 100 and 300 kg, which is suitable for the storage of small parts and lighter goods. Its cost is relatively low, and it is strong and not easy to deform.
Medium-duty shelf shelves: Medium-duty shelf shelves are similar to light-duty shelves, with simple installation, plug-in structure, and convenient and flexible combination and disassembly. Its columns adopt a butterfly hole structure, which can be locked by the weight of the stored goods, and a punching hole is set every 50 mm, which can be adjusted up and down, left and right. The load-bearing capacity of each layer of the medium-duty shelf shelves is between 300 and 500 kg, which is suitable for storing large and heavy goods. Its structural features include large moment of inertia, strong layer capacity, strong impact resistance, etc. It is one of the most widely used shelves.
Heavy-duty shelf: Heavy-duty shelf has the largest load-bearing capacity, generally between 500 and 1,000 kg, and is suitable for storing small batches of multiple varieties or large batches of a few varieties, especially for use in higher warehouses. It is mostly used in manufacturing and distribution centers. Heavy-duty shelf is also a plug-in combination, which is easy to install and disassemble.
In addition, there are some special types of shelf, such as rivet shelf, which is made of angle steel material, without bolt connection, and the height of the shelf interval can be adjusted arbitrarily, which is suitable for the storage of small quantities and a variety of goods.
