Firstly, it is important to consider the size and capacity of the rack. Determine how many trays the rack can hold and whether they will suit your needs. Also, pay attention to the height of the shelves to ensure that your long pans or trays will not collide with the top shelf.

Secondly, pay attention to the materials used. Commercial racks should be sturdy and durable to withstand heavy use. Preferred materials include stainless steel or aluminum.

It is also helpful to choose a rack with adjustable shelves. This will allow you to adapt the rack to different sizes and shapes of dishes. Additionally, pay attention to additional features such as wheels for easy movement or protective coating for easy cleaning.

Hey there! I've been using a commercial bakers rack https://www.amgoodsupply.com/storage-shelving/bakery-racks/ for a while now, and it's been a game-changer in my bakery. One crucial factor to consider when purchasing is the spacing between the shelves. Make sure there's enough clearance to accommodate your tallest items comfortably. Additionally, think about the environment the rack will be in. If your bakery tends to get humid, you might want to look for a rack with rust-resistant coating to ensure longevity. As for where to buy, I've had good experiences with both online restaurant supply stores and local commercial kitchen equipment vendors. It's worth checking out both options to compare prices and find the best deal!
