What is the storage system that allows pallets to be stored multiple units deep or high called?

The storage system that allows pallets to be stored multiple units deep or high is referred to as high density storage. This method maximizes the use of vertical and horizontal space within a warehouse, making it possible to store a greater number of items in a smaller footprint. High density storage typically involves systems such as pallet racking or shelving that are designed to accommodate more units vertically, which is especially beneficial in operations where space is limited or where there is a need to increase storage capacity without expanding the physical building.

Utilizing high density storage can improve efficiency in inventory management and reduce costs associated with warehouse space. It is particularly effective for businesses that deal with a high volume of goods, as it allows for faster retrieval and organization of items.

The other terms do not accurately describe a storage system capable of handling pallets in this manner. Inventory turnover refers to the rate at which inventory is sold and replaced, kitting involves assembling different items into a kit for shipping or sale, and order typically refers to the act of requesting or purchasing goods, rather than a storage method.
