A solid wall of pick faces at hand level, pallet storage overhead...

Pallet racks that utilize carton flow tracks are an excellent way to mix slow and fast-moving items in the same storage footprint. With overhead pallet storage, bulk quantities are easily transferred to active operation later. Placed along a line of conveyors, or used with cart-based picking, flow racks provide a solid wall of pick faces operators can quickly access to service incoming orders.
Gravity flow modules work best for multiple-item orders, when average supply holding time is minimal, and when item weight is important. First-in, first-out (FIFO) storage gives you automatic inventory rotation. Whether you need a bay or two of flow storage or a long row of gravity-driven pick faces with pallet storage above, utilizing rack-mounted flow storage gives you the flexibility to change and reconfigure.
