Carton flow expedites pick operations by making stock accessible in an easily replenished first-in/first-out pattern. Gravity flow racks can reduce labor costs up to 75% in pick operations compared to static storage picking by delivering cartons and split case goods to the pick aisle rather pickers pulling from the static pallet rack storage. It is a commonly used storage/picking method in many operations, but there are many options and types of flow storage available. Which fits your need best?
