The shelf manufacturer tells you what the main and secondary shelves of the warehouse shelves are

　　When purchasing a warehouse shelf that suits your needs, you first need to understand its structural characteristics. Each product in each industry has its own unique name and characteristics. If you are not familiar with this industry and do not understand this product, it is difficult for you to understand what it is.

　　In the warehouse shelf industry, in general shelf types, when actually installed and used, it is usually presented in the form of an organic combination of the main and auxiliary shelves. Such as heavy-duty shelves, gravity shelves, etc. So, what is the main frame and what is the sub frame

　　Modern modular shelves mainly form a large storage structure through continuous connections between columns and beams. In theory, wireless combination connection can be achieved. The main frame is the "support" of the subframe. It generally consists of two columns and two crossbeams and can be used independently. If you continue to hook the crossbeam at the back, you can continue to increase a lot of usage space, and the part behind the column is the subframe.

　　In fact, a main frame can connect countless sub frames. Due to the omission of columns from the subframe, the total cost has been reduced. If this form is not adopted, the cost of manufacturing and using warehouse shelves will increase. The selection of main and auxiliary shelves should be determined based on actual storage requirements.
