The purpose of installing a pallet racking system is to utilize the storage space of your warehouse in the most efficient manner possible. To this end, there are many points to consider when choosing the rack components, including the space they take up and how much weight they can safely hold. To give you some insight into how to calculate pallet racking needs, we explain the key factors in choosing the rack parts.
Thinking of Weight
An initial point to consider is the weight of the items you plan to store. This will affect the dimensions of the vertical uprights and the horizontal beams that you pick. The more depth, or thickness, that an upright and a beam have, the more weight they can support. However, this strength is offset by the length of the components, as a longer beam or upright with the same thickness of a shorter one will not be as rigid as that shorter version. You need to know the maximum load capacity you will need from the racks so that you can select the correct parts.
Fitting It Into the Available Length
Next, you must figure out how to fit the racks into the length you have available for them in the warehouse. Say you have 80 feet of space that can contain a rack lengthwise. The total length of each rack must then be less than or equal to 80 feet. As an example, say the beams that will work for your inventory loads are individually 6 feet. You divide 80 by 6 to get about 13.3, which you then round down to get 13 bays total that you can fit. Take the 13 bays you’ve just calculated and multiply them by 6 feet to get 78 feet.
This leaves 2 feet for all the uprights, which will be one more than the number of bays (14). If the width of each upright is 2 inches, you multiply this by 14 to get 24 inches, or 2 feet. In total, you have filled up the 80 feet you had allotted. If the length goes over 80, you’ll need to adjust the dimensions of the beams and uprights.
Finding the Number of Parts
Once you know how many bays will be present in each rack, you can figure out the number of each part that you will need. For instance with regards to beams, you know that you will need to form 13 bays and each bay will need 2 beams, so you get 26 beams for one level of racking. Since your racks will be multistoried, multiply this number by the amount of levels your rack will have. If your rack will have 3 shelves, you will multiply 26 by 3 to find that you need 78 beams for a rack.
In the end, though, you need an expert to assist you in calculating your pallet racking needs to check that no mistakes are made at any point along the way, as well as to keep the racks within regulations.
