Also known as gravity flow racks or dynamic flow racks, are a type of storage system that facilitates continuous inventory rotation. They are designed to optimize the storage and retrieval process for date-sensitive products, especially those stored on pallets. This system is particularly beneficial for companies dealing with perishable goods or products with limited shelf life.

The flow-through rack system operates on a FIFO principle, ensuring that the first pallet loaded into the system will be the first one to be picked for distribution or use. This helps prevent product expiration and reduces waste by ensuring that older products are used before newer ones.

Flow-through racks maximize storage density by utilizing the depth of the rack for pallet storage. Pallets are loaded from the back aisle, and they glide smoothly down inclined rollers or wheels toward the front picking aisle. As a result, space is efficiently utilized, and products are easily accessible for picking.

The design of flow-through racks enables faster order picking since products move toward the front automatically. This reduces the time and effort required for manual handling and can increase overall warehouse productivity.

With a continuous rotation of inventory, it becomes easier to manage stock levels and monitor expiration dates. This helps in maintaining optimal inventory levels and reducing the risk of stockouts or expired products.

The flow-through rack system streamlines the picking process, reducing the need for excessive manual labor. This can result in cost savings and increased efficiency in warehouse operations.

Flow-through racks are particularly suitable for items with short shelf lives, such as perishable goods, pharmaceuticals, and certain consumer products.
