Laying out warehouse pallet racking can be a frustrating task, especially when it comes to figuring out how to accommodate building columns. It may seem that no matter how you rearrange your layout, you may still have difficulty placing the columns out of the rack or not in the aisles.
At Cranston Material Handling, we’ve put together some tips on how to space your building columns to avoid these frustrations and design a pallet racking system that best suits your needs.
In most cases, architects and engineers will space building columns 40 or 50 feet apart., following standard steel mill member lengths. Although this is the general practice, you can make the best use of your space by designing the building around what you intended to use it for and the equipment inside, allowing you to modify these lengths to make the best use of your space.
When optimizing your pallet rack layout, there are two measures you can take to avoid having your building columns fall outside of the racking or within the forklift drive aisles:
To avoid losing storage locations, it is essential to try to position the building columns within the flue spaces.
Below we’ve put together the best building columns spacings for a variety single-deep pallet racking design. As an example, we’ve determined the building column spacing for 12” x 12” building columns and 48” deep pallets, with no pallet overhang. To determine these measurements, we use the formula:
For this example, we will look at a 40-ft building column spacing for single-deep pallet rack. For 48” single-deep pallet racks with 12” flue spaces, you would have 11’-0” aisles.
Wide Aisle – A wider aisle may be needed if your operations require faster loading and unloading. With a 156” aisle width, you would need to increase the building column space by 44’-0.
Narrow Aisle – A narrow aisle, with a 120” width can help you optimize your space and save on square footage. This size aisle requires on a 38’-0” building columns space.
Very Narrow Aisle (VNA) – If you have the proper equipment a 60” very narrow aisle with will allow you to an on an additional set of pallet racks. Very narrow aisles only require a 42’-0” building column spacing.
At Cranston Material Handling, we understand how challenging it can be to layout and design a pallet rack system while determining the best building column spacing in your building to ensure you get the most out your space.
