If your company handles only one type of inventory or SKU, you will fill your warehouse with an entirely different type of racking system than you would if you have a wide range of inventory types to be handled.
Minimal variety in inventory means you can pack identical pallets -one after the other- into push back, drive-in, or skate wheel systems that offer awesome storage density due to their lack of need for aisles.
Conversely, if your company handles a wide variety of material, you’ll need the ability to access that material and thus will need to store your pallets in conventional rack systems with aisles. But, even conventional aisle-based rack systems can be optimized to increase storage density and pallet positions. More about that later.
