Selective Pallet Racking


Selective Pallet Rack Overview

Selective rack is the most common type of storage solution found across the United States. It is a static system 
combining beams and frames to provide proper storage for pallets and other large items. Selective rack also comes with a variety of accessories and options.

Frames are the vertical elements of the racks. They are rectangular in shape and come in a variety of heights, widths and depths depending on the load being stored and the model of frame being used. A standard frame consists of two posts connected by a series of horizontal and diagonal struts and includes a foot plate welded or bolted to the bottom of each post.


Beams are the horizontal elements of the system and are typically orange. Interlake Mecalux offers several different sizes and profiles of beams with varying capacities to fit the needs of the customer and the items being stored. Pallets are placed directly on the beams. Special accessories can be added to help support loads or store specialty loads such as drum coils.



General Design Considerations



Pallets are flat transport structures that support goods in a stable fashion while being lifted by a forklift. They supply the structural foundation of the unit load and as such are an important consideration for the design of any warehouse.

Interlake Mecalux products are optimized to the dimensions of the standard pallet used in the U.S., the Grocery Manufacturers' Association or GMA pallet.




In any design, it is important to consider the vertical clearances required to successfully lift the load and pallet off the rack using a forklift or pallet jack. As an industry standard, the distance from the top of the pallet load overhead is 4" to 6".

The pallet mus extend 3" beyond the frame depth on either side to ensure proper pallet support.



Clearances Between Pallets and Posts

Each pallet should be positioned 3" or 4" from any adjacent post or pallet, unless the bay has a 3 pallet width. In this case, a 5" clearance should be provided between pallets and 4" between post and pallet.
