Pallet Flow Systems
Introducing the DeepFlo™ Pallet Storage System, the high density, first-in/first-out storage system that reduces your warehousing costs while it increases your total usable storage space. DeepFlo Storage Systems consist of two elements - a rack structure and dynamic flow components set at a constant pitch.
The DeepFlo System maximizes your storage density by putting gravity to work. The system's flow-through gravity-fed design allows pallet loads placed at the entry end of the system to flow under continuous speed control to the discharge end for convenient, timely removal. As a result, pallets automatically index for accumulation.
As pallets in different lanes are unloaded, those located behind move forward as replacements. If the storage lane, or stock keeping unit (SKU), is empty, the pallet load moves to the first position.
The DeepFlo System also transforms wasted aisle space into valuable FIFO storage, with flow lane depth limited only by the size of your building, so you can put nearly every foot of floor and air space to profitable use. It's as remarkable - and as effective - as it sounds.
Pallet flow systems are designed to interface with future equipment including AS/RS, WMS and Order Pick Modules. With over 30 years of experience DSS provides the most effective solutions to meet your warehousing needs.

The number of flow rails required under each pallet depends on:
- Pallet weight
- Bottom boards surface
- Type of bottom boards (hard surface or soft wood)
- Bottom board thickness
When typical GMA pallets are used, standard rail configurations can be used:
- 200lbs - 2,000 lbs per pallet – (2) rails
- 2,000 lbs - 2,800 lbs per pallet – (3) rails
- 2,800 lbs - 3,500 lbs per pallet (4) rails
If weights fall between two ranges, other pallet and load conditions will be reviewed to assist in selecting the proper rail configuration.
Different pallet weights, within a given range, can be stored in the same lane.
