When you want to buy warehouse shelves that suit 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 the industry and the product, it will be difficult for you to understand what it is.
In the warehouse racking industry, in general rack types, when actually installed and used, they are usually presented in the form of an organic combination of the main rack and the sub rack. Such as heavy duty racks, gravity racks, etc. So, what is the main frame and what is the sub frame?
Modern modular racks mainly form a large storage structure through continuous connections between columns and beams. In theory, a wireless combination connection can be realized. The main frame is the “support” of the sub frame. Generally consists of two uprights and two beams, which can be used independently. If you continue to hook the beam at the back, you can continue to increase a lot of use space, and the part behind the column is the subframe.
In fact, one main frame can connect countless sub-frames. Since the column is omitted from the subframe, the total cost is reduced. If this form is not adopted, the cost of manufacturing and using warehouse shelves will increase. The choice of main and auxiliary shelves should be determined according to actual storage requirements.
