When customers ask what the starter bay and add-ons are, do you find it difficult to explain verbally? Please take a look at this article.
In the shelving and storage rack industry, among the common types of shelves, they are usually presented in an organic combination of main and auxiliary shelves during actual installation and use. For example, heavy-duty racking, gravity racking etc. So, what are the starter and add-on bays? Let’s first take a look at a clear racking identification diagram.

Modern modular shelves primarily form a large-scale storage structure through the continuous connection of vertical upright and horizontal beams. A typical type of shelf is the heavy-duty shelf, which is generally composed of a main frame and auxiliary frames to create a large storage space. Theoretically, they can be connected in an infinite combination. Here, the main frame of the shelf can be seen as a “support” for the auxiliary frame; it is usually made up of two vertical uprights and two horizontal beams, and can be used independently.

If horizontal beams are further connected at the back, it can significantly increase the usable space, and the part connected to the vertical posts is the auxiliary frame.

In fact, one main frame can connect to countless auxiliary frames. Since an auxiliary frame omits one vertical post, the overall cost is reduced. If this form is not adopted, the costs of manufacturing and using the shelves would increase. The choice between main and auxiliary frames should be based more on actual storage needs.
