　　Many buyers who have not customized storage shelves are unclear about the difference between the main and auxiliary shelves, or have never heard of these two terms. There may be differences between main and sub racks in some types of warehouse shelves, but not all types of warehouse shelves are divided into main and sub racks. What types of warehouse shelves do the main and secondary shelves exist in, and what are their differences? So today we'll talk about the difference between the main shelf and the sub shelf!

　　First of all, let's talk about the main frame. The main frame is composed of two frames+beams and other components, and it is called the main frame when there are two frames. The main shelf can be placed and used separately. If you want all shelves to be placed and used separately, you can directly customize all the main shelves.

　　The subframe is composed of a frame and beams, and other components. The difference between it and the main frame is that it has one less frame than the main frame and cannot be placed and used separately. It needs to be connected to the main frame in order to be used. For example, if a row of shelves is divided into 10 small shelves, it can be used by assembling one main shelf and 9 sub shelves together.

　　Why should we divide the main frame and sub frame? Because the subframe is one frame less than the main frame, the price will be cheaper than the main frame. If the number of shelves in the warehouse that need to be purchased is large, and the number of sub racks used is much larger than the main rack, it can save a lot of procurement costs.

　　The common warehouse shelves that distinguish between main and auxiliary shelves are pallet shelves, crossbeam shelves, shelf shelves, and fluent shelves. Not every type of shelf has its own main and auxiliary shelves, so before purchasing storage shelves, you can first understand whether the shelves you want to purchase are divided into main and auxiliary shelves, in order to avoid wasting costs by ordering all the main shelves instead of all the main shelves.
