The shelf factory teaches you how to distinguish the main and secondary shelves of storage shelves.wire shelving units on wheels Processing

　　1. In the types of storage shelves, both heavy-duty and medium-sized shelves have main and auxiliary shelves. Although their composition is different, the basic structure is the same, consisting of beams and columns. However, medium-sized shelves have more layers than heavy shelves, and each main shelf consists of two pairs of structures and beams, while auxiliary shelves consist of one pair of structures and beams.

　　2. Storage shelves can be distinguished between main and sub racks based on whether they can be placed independently, which means that the main rack can be placed separately, while the sub racks can only be placed as needed. In other words, the secondary shelves cannot be placed separately.

　　3. Because the subframe has one less column structure than the main frame, the price cost of the subframe is lower than the cost of the main frame, and the price difference is the price of one column.

　　However, some storage shelves, such as attic shelf platforms, do not have a distinction between main and secondary shelves. In the loft type shelf system, the medium or heavy shelves are generally used as the main supporting floor. The floor is generally cold rolled steel floor, striped steel floor or steel grating floor. In recent years, cold-rolled steel flooring has been increasingly applied, with advantages such as strong load-bearing capacity, good integrity, good load-bearing uniformity, high accuracy, flat surface, and easy determination. There are many types to choose from, easy to equip with lighting systems, and easy to access and operate. The load on each layer of unit shelves is generally less than 500 kilograms, with a layer spacing of generally 2.2 to 2.7 meters, and the height of the top shelf is generally about 2 meters, fully considering the convenience of staff operation.
