PALLET RACKING SOLUTIONS

SELECTIVE PALLET RACK
A selective rack is a steel storage system arranged in either single or back-to-back (double) rows. Each of the rows offers a bay or number of bays in the down aisle direction.

DOUBLE DEEP RACK
Double deep rack can accommodate two pallet loads, stored back-to-back and requires a special fork truck called a deep reach truck. The double deep rack offers medium storage density and low cost.

DRIVE-IN RACK
Drive-in systems offer a highly efficient method of storing large quantities of similar loads, by allowing the forklift driver to enter the rack system and place the load on structural rails.

PUSH-BACK RACK
Push back racks offer the same storage density as drive-in racks but with greater selectivity. Loads in each lane rest on a cart on a rail that slopes slightly toward the front.

PALLET-FLOW
In this first-in/first-out (FIFO) system, pallets are loaded at the top end of the slightly inclined rack and glide safely and effortlessly at a controlled pace to the other side.

CARTON-FLOW
Carton Flow Rack can be used for both cartons and pallets. The systems may be many units deep and are most often used in situations where the carton or pallet at the front is going to be picked first.
RACK SYSTEM CONFIGURATIONS: STORAGE LOGIC
| Racking System | Density | Selectivity | Inventory Flow | Best Application |
|---|---|---|---|---|
| Selective | Low | 100% | FIFO | High variety of SKU's; fast turnover; requires immediate access to every pallet. |
| Double Deep | Moderate | 50% | LIFO | Storing 2 pallets of the same SKU deep; increases density while maintaining reasonable access. |
| Drive-In | Very High | Low | LIFO | Storing large quantities of the same SKU; minimizes aisle space; ideal for cold storage. |
| Push Back | High | Moderate | LIFO | High-density storage (2-6 deep) that allows access to different SKUs on different levels. |
| Pallet Flow | Very High | Moderate | FIFO | High-volume perishables or time-sensitive goods; pallet flow via gravity from load to pick face. |
| Carton Flow | High | 100% (for cases) | FIFO | Piece picking or case picking; gravity-fed rollers for smaller items rather than full pallets. |
| Roll Out | Low/Moderate | 100% | N/A | Storage of heavy dies, molds, or motors; shelves extend out 100% for crane/hoist access. |

PALLET RACKING TYPES
WELDED PALLET RACKING
Roll-formed welded pallet racking is the most popular selective pallet racking type, as it is the most versatile. There are variety of column sizes and gauges available to accommodate any load size or capacity, and is readily available from stock.
KNOCK-DOWN RACKING
Roll-formed, knock-down pallet racking differs from welded pallet racking, because the frame structure is bolted together, rather than welded. Knock-down pallet racking is easy to install, and is available in many configurations.
STRUCTURAL STEEL RACKING
Structural steel pallet racking is designed for high-capacity loads, and can be used in multiple configurations. The open channel design and thick cross-section makes the structural steel racking strong enough for any application.
CONSTRUCTION & MATERIALS
| Type | Definition | Durability & Impact Resistance | Key Characteristic |
|---|---|---|---|
| Structural Steel | Made from hot-rolled c-channel steel (like I-beams) | Extreme. Can withstand significant forklift impacts. | The "heavy duty" option. Easy to keep clean (open channel); usually bolted connections. |
| Roll Formed (Standard) | Cold-rolled steel sheets formed into column shapes. | Moderate. Susceptible to forklift damage. | The industry standard. Versatile, lighter weight, and generally lower cost than structural. |
| Welded | Frames are welded together at the factory. | High. Rigid connections. | Shipped as one piece. Saves installation time but higher freight cost. |
| Knock Down | Frames are bolted together on-site. | Moderate to High (dependent on assembly). | Shipped efficiently (compact). Parts can be easily replaced if damaged without replacing the whole frame. |
