If you require alternate or additional pallet and storage rack options, we have the ability to provide what you need. Please contact us directly and we will make every effort to accommodate your requests.

  • Selective Racking Application

    Selective Rack

    Select Rack - Single Selective Racking - Standard Rack: The “selective” pallet rack is the most common in the materials handling industry. These racks provide 100% selectivity and accommodate a wide variety of load types. It is the lowest cost per unit stored. This type of rack can be used with virtually any type of forklift equipment. Using Deep-Reach forklift trucks and Swing-Reach forklifts with this type of rack can increase storage density dramatically.

  • Arbor Double Deep Racking System

    Double Deep Racking

    Double deep pallet rack uses selective rack configured so one pallet is stored behind another up to two pallets deep. This requires a special forklift that is only slightly more expensive than a regular reach truck. Because one pallet is stored behind another this type of storage requires multiple pallets of the same SKU. Double deep pallet storage will increase storage density by 15-20% over selective pallet rack.

  • Deep Lane Pallet Racking - Maxipacker Pallet Shuttle

    Combining the ability to store 6-100+ pallets deep as high as you'd like creates incredible density while minimizing the need for fork lifts or other equipment to transport pallets. Unlike Drive-in rack there is less honeycombing and much greater selectivity. Maxipacker deep lane pallet racking can be used for LIFO or FIFO storage solutions. The most common applications for Maxipacker deep lane pallet tacking systems include the storing and transporting of time sensitive product of production high volume just-in-time cross docking, and consolidation of outbound loads at the shipping dock, where each lane can represent an outbound order. Originally designed for the freezer industry, Maxipacker deep lane pallet racking has found many uses in ambient temperatures as well

    Arbor Drive In Racking Applications

    Drive-in Racking

    When you have an even greater number of pallets per SKU you may consider Drive-In or Drive-Thru racking. In this type of rack system the forklift truck drives into the rack structure to pick up or drop off the pallet load. By doing so you remove wasted aisle space and improve the use of the warehouse cube. Selectivity is limited to those pallet loads facing the aisle and it is very difficult to maintain a high degree of storage density in the racking structure. The difference between Drive-In rack and Drive-Thru rack is simple. Drive-in rack is accessed from one side. Drive in Rackingis accessed from one side. Drive-Thru rack can be accessed from either side and the lift equipment can literally be driven thru the system.

  • Push Back Racking Application

    Push Back Racking

    When loaded this rack will look like Selective rack. However, similar type SKU pallets are placed one behind another from 2 – 7 pallets deep. Unlike Double deep rack a special forklift is not needed. Push back rack can produce even better cube utilization with less of a honeycombing effect you may experience in Drive-in rack. This type of rack has carts that the pallet rests on. As you place the second or deeper load in the forklift truck actually pushes the previously placed pallet(s) back. As pallets are pulled form the system the carts with the pallets on them will ease forward towards the aisle. This type of system is for First In Last Out (FILO) storage and is not the best for time sensitive materials.

  • Cantilever Racking System

    Cantilever Racking - Long Load Storage

    This is the selective racking for long loads and is common in the materials handling industry for loads over 12' long. These racks provide 100% selectivity and accommodate a wide variety of load types. This type of racking can be used with any type of forklift equipment although space efficiency is greatly improved using a Raymond 4-D® or Raymond Sideloader forklift truck.

  • Arbor Deep Lane Pallet Storage

    Pallet Flow Racking - Deep Lane Pallet Storage

    Pallet flow racking is loaded from one end and unloaded from the other. It’s best applied to storing multiple pallets of the same SKU in a high velocity operation. Pallet flow rack can store many pallets deep. Pallets flow down a slope from the loading end down to the discharge end. Because each pallet flow lane is sloped the deeper the number of pallets stored the higher the loading end of the system. Often times the flow lane depth is determined by the available vertical clearance in the building. This guarantees (FIFO) storage and is well suited for date sensitive materials.

    Pallet Rack Storage Q&A

    Pallet Rack Storage can be a complicated topic without an expert to guide you. That's why Arbor Material Handling is available to answer any questions you have by using the query form at the bottom of this page. Ask us anything and we will respond to you with a helpful and comprehensive answer. Here are some of the top questions that are often asked about Pallet rack Storage.

Can you explain warehouse's pallet rack distribution order?

The two primary methods of inventory valuations are "first in, first out" - also known as FIFO - and "last in, last out"- which is also referred to as LIFO. If your operation is involved in managing perishables- like food- then there is a very high likelihood that your facility is designed with FIFO as a strategy. FIFO storage operations benefit from high storage density and should be using pallet flow racks, which are also know as “gravity flow racks”. For products that are held in storage for a long period of time - and that use the LIFO strategy - you would look at configurations that use Push Back Pallet Racking Systems.

What are your order picking and placing practices?

Is your facility’s focus on high-density storage, ie. is the layout more about tall, elevated racks? Do the pallet racks need to accommodate special equipment like lift trucks, or pallet jacks, or possibly warehouse conveyors because these will impact the design of aisle widths and pallet rack dimensions? Be sure to also assess your warehouse’s picking processes. Determine if your warehouse staff picks full pallets, or partial loads or perhaps are they more inclined to pick individual products. How you answer that will dictate the setup for maximum productivity.

Why are pallet rack load parameters important to understand?


Pallet rack weight capacity is an important consideration for both efficient warehouse operations and maintaining safety. Your warehouse design consultant or pallet rack storage expert will examine, consider and design for the upper limits of your pallet rack, as well as the average weight of each pallet load.

What is Carton Flow Racking?

A carton flow rack system is designed to move cartons or boxes. It is designed to move a high volume, of fast-moving inventory.  It’s FIFO (first in, first out) design allows for the carton flow rack system to be loaded and unloaded at the same time. This allows for maximum order-picking efficiency. Since it is used to store individual cartons and not full pallets, it can accommodate a big volume of SKUs. Industries that tend to use this design include food and beverage, medical, frozen foods, automotive and general carton distribution. Carton flow rack is also ideal for liquor or beer storage applications, as it allows cases to be loaded from one side and picked from the other.

Carton Flow Racking systems are built with upright frames, cross beams, and metal rollers (or skate wheels) that span the width between the two beams. One beam is elevated higher than the other so that it is gravity driven. This creates a sloped surface that cartons slide on. When a carton is loaded onto one side it moves down the slope pulled by gravity and when it arrives, it is ready to pick on the other side. If it is behind other cartons then it moves towards the picking side of the rack system. The boxes ahead of it are removed by warehouse workers (or in retail applications by consumers). 

Carton flow tracks come in several different designs. One version is built on a full wheel bed and is made up of several rows of aligned wheels.  This design is not as common as it once was.  A newer style is made from a heavier duty steel roller track and is used for more demanding applications.  A second, newer style is similar to the traditional wheel bed, but it has key differences. It features wheel beds that consist of smaller pieces. The wheels are often staggered and they are also stronger than smaller traditional wheels.
