Interroll vs. Spantrack: Which Carton Flow System Is Right For You?

July 9, 2020

The smartest of storage rack systems, carton flow rack is a gravity flow-based racking solution used mostly by warehouses and distribution centers. Essentially, carton flow racking systems follow the dynamic FIFO (First-In-First-Out) method of product inventory management and use a back-load design. Products are first loaded into rear part of rack which are then slid forward for easy picking. Here you have shelves set at a slight pitch with wheels to slide products automatically to frontal part of racking. The moment a product is picked up from the front part of the rack, the item immediately behind it moves forward in its place and thus the cycle goes on.

Carton Flow racking keeps the merchandise set up in perfect order and also eases the product pick-up process. It can reduce the volume of labor involved for picking as well as stocking tasks. Interestingly, carton flow racks can save around 75% labor costs in comparison to static dated storage solutions. Compared to traditional pallet racks, the carton flow option can save you up to 50% of floor space.

The storage rack accessory market is packed with a diverse range of options, especially when it comes to carton flow racking. The post below offers a brief on the most popular carton flow racking models so that you can make an informed selection.
