Carton flow rack systems: 

Known as sliding shelves, fluent rollers using aluminum, sheet metal and other smooth strips etc..

Use the weight of the inclination angle, shelf-level goods from one side of the channel inventory.

Pick up the other side of the channel achieve FIFO, convenient storage . 

High fluent shelf storage efficiency, there is commonly a sliding container turnover box, parts boxes and cartons, suitable for large quantities of goods and short-term storage and picking.

These systems are essentially miniature versions of pallet flow systems where movement is largely driven by gravity to transport a load from one side of the system to the other. 

Carton flow rack is used for light load packages. 

Flow rack storage is highly efficient and suitable for short-term storage and warehousing of large quantities of goods.
