The Complete Guide to All Types of Pallet Racking

Pallet Rack, Types of Pallet Racking

If you’re running a warehouse or distribution center, your racking system is more than just shelving — it’s the backbone of your operation. The right pallet racking system can maximize floor space, improve workflow, and reduce safety risks.

But with so many options, how do you know which type is right for your space?

We’re breaking down every major pallet racking system to help you make the smartest choice for your business.

1. Selective Pallet Racking

✔ Most Common. Most Versatile.

This is the classic go-to system. It allows direct access to every pallet and is ideal for facilities with many different SKUs.

  • Best for: General warehousing, fast picking
  • Inventory method: First-In, First-Out (FIFO)
  • Pros: Simple, cost-effective, easy to install
  • Cons: Lower space utilization than high-density systems
2. Drive-In Racking

✔ Store deep, save space.

Forklifts drive into lanes of the rack system to load and retrieve pallets. This style is great for storing large quantities of the same product.

  • Best for: High-volume storage of similar items
  • Inventory method: Last-In, First-Out (LIFO)
  • Pros: High density, maximizes space
  • Cons: Limited access, higher chance of forklift damage
3. Drive-Through Racking

✔ Like drive-in, but with access on both ends.

Same structure as drive-in, but open on both sides — so forklifts can enter from one end and exit the other.

  • Best for: High-turnover goods that still need density
  • Inventory method: First-In, First-Out (FIFO)
  • Pros: Efficient inventory rotation
  • Cons: Requires more aisle access than drive-in
4. Push-Back Racking

✔ Smart, gravity-assisted storage.

Pallets are loaded onto nested carts that roll backward. When one is removed, the next rolls forward automatically.

  • Best for: High-density storage with moderate selectivity
  • Inventory method: Last-In, First-Out (LIFO)
  • Pros: Great for maximizing selectivity and density
  • Cons: Higher cost, LIFO only
5. Pallet Flow Racking (Gravity Flow)

✔ High-throughput, automatic rotation.

Pallets move on roller tracks from the loading side to the picking side using gravity.

  • Best for: Perishables, high-volume SKUs
  • Inventory method: First-In, First-Out (FIFO)
  • Pros: Fast picking, efficient space usage
  • Cons: Higher setup cost, requires precision
6. Double Deep Racking

✔ Two pallets deep = better space usage.

Selective racking, but placed two deep. Requires a deep-reach forklift for access.

  • Best for: Warehouses storing pallets in bulk
  • Inventory method: LIFO (or limited FIFO)
  • Pros: Higher density than standard selective
  • Cons: Less access, special equipment needed
7. Carton Flow Racking

✔ For boxes and case picking.

Uses gravity-fed roller tracks to move boxes or cases to the pick face.

  • Best for: Order picking, e-commerce, retail
  • Inventory method: First-In, First-Out (FIFO)
  • Pros: Increases pick efficiency
  • Cons: Not for full pallet loads
8. Mobile Pallet Racking

✔ Maximize storage in minimal space.

Racks are mounted on tracks and can move to create or close aisles as needed.

  • Best for: Cold storage, small-footprint facilities
  • Inventory method: Varies
  • Pros: Extremely high storage density
  • Cons: Slower access, higher investment
9. Cantilever Racking

✔ Store long, bulky items.

Great for items that don’t fit on a pallet — like lumber, pipes, or steel.

  • Best for: Furniture, building materials
  • Inventory method: Manual or forklift
  • Pros: Flexible for non-standard sizes
  • Cons: Not suitable for pallets
10. Mezzanine Racking Systems

✔ Go vertical — double your space.

Combines racking with elevated platforms to add extra floors for storage or picking.

  • Best for: High ceilings and growing operations
  • Inventory method: Varies
  • Pros: Efficient use of vertical space
  • Cons: Requires planning, structural approval
Which Racking System Is Right For You?

The right system depends on your:

  • Inventory volume and movement
  • Access and rotation needs
  • Forklift type and aisle width
  • Budget and growth plans
