Good news: an array of warehouse-hacking pallet storage solutions exist to turn your facility into an organized and profitable picking machine. Bad news: without underpinning your precise needs the options for racks can be a little difficult to sift through.

pallet racks warehouse essentials

Before your company spends significant chunks of the budget for a system that isn’t a true solution, get clear on the following:

  • Your max spend for a racking solution
  • The total floor space and ceiling height available for pallet storage
  • Number of different products for which you need rack storage
  • Frequency with which you need to access products in your racks
  • Shelf life of your products
  • What kind of truck access you’ll need including lift height

From there you’ll have the basics you need to approach the following pallet solutions from an informed place. We’ve also listed some pro/con factors for quick reference:

Cantilever Racks

Maximizing space is top-priority in any warehouse operation. When storing lengthy, over-dimensional products like tubing or lumber it becomes positively critical. Structural or Roll-Formed Cantilever Racking offers compact and adaptable storage that differs from standard, less flexible pallet racking.

An absence of front columns means bulky or oddly shaped items like furniture can easily take up residence across an entire row without impacting your limited space. These racks also accommodate substantial handling clearance for larger, over-length items like piping or carpet rolls thanks to the increased horizontal space.


  • Long and open clearance leads that are perfect for lengthy items like building materials or furniture
  • Flexible multi-length levels can be adjusted for different SKUs


  • Warehouse space typically needs to have generous aisle widths large enough to accommodate picking and restocking

Drive In Pallet Rack

High-density warehouse spaces that accommodate products with long shelf lives are always in need of more storage capacity. Cost-effective drive-in pallet racks can help increase storage by up to 75%. They’re especially great for Last in, first out (LIFO) or First in, first out configurations (FIFO) where products don’t always require immediate accessibility.

The decreased aisle space reduces the square footage requirement and simplifies forklift paths by making the entry and exit point at each opposite end the same.


  • Cost-effective solution for LIFO or FIFO access
  • Unmatched storage potential for items which don’t require immediate access


  • Difficult to reach all non-end rack pallets by forklift
  • Potential for rack damage from fork trucks as they navigate narrower aisles

Push Back Rack

Push back racks are often the front-runner solution for warehouses challenged by limited space. That’s because they offer as much as 90% more product storage than selective rack systems by eliminating the need for multiple loading/unloading aisles.

Push back racks work similar to a vending machine. Once a product is selected, subsequent pallet carts to roll forward. The mechanism consists of a series of nesting carts that move along steel rails. This provides easy access to an array of products and SKU’s that can each be stored at different levels. Not unlike a drive-in pallet rack, the system uses an LIFO inventory control approach. However in this system, the fork trucks needn’t enter the rack.


  • High storage density without the need to drive into the rack, limiting potential damage
  • Front loading/unloading eliminating the need for multiple aisles


  • Inability to access all pallets
  • Limited depth– restricted to 4-5 lanes max

Pallet Flow Rack

High volume and fast moving product is a unique combo that requires a special solution to stay on top of picking. A high-quality gravity-fed pallet flow rack system is just the solution to help cut costs while saving on valuable space.

Inclined shelves use gravity’s natural force to naturally draw palletized loads forward to the designated picking position. Deep pallets save on square footage by acting as substitutes for aisles. Product is loaded from one side and picked from the opposite side.


  • Products can be stored 20+ pallets deep creating an ideal high-density storage solution
  • Singular loading/unloading point limits damage from forklifts
  • Flow racks can be added to nearly any existing pallet rack configuration


  • Can be a more costly investment than other storage options
  • Poor accessibility to all pallets

If your warehouse could benefit from additional floor space and increased storage, these pallet storage options can help.
