Longspan Shelving Guide


Longspan Shelving is United Racking’s Heavy-Duty shelving system which is ideal for use in a Warehouse, Store, Garage, Workshop or the even the Back Shed – pretty much anywhere!!

The United Range of Longspan Shelving is so extensive that we think we have the biggest range in Australia. We have 20 standard frame sizes, 6 beam lengths and 3 shelf material materials. This adds up to literally thousands of options, all readily available so we are pretty sure there is not a space we can’t fit out with our Longspan. Being a modular system means you don’t have to have 3 or 4 levels, you may need to add some extra shelves and have 6 or 7, not a problem with Longspan Shelving perth, it’s all easy.

Longspan Shelving consists of 4 key features making it the easiest storage solution to set up, modify and build. To help with understanding these features we have outlined them in the below summary …. but if there is anything else you need to know, give us a call or send us a message, we love to chat about this stuff.


End Frames “Uprights”

The End Frames, or more commonly knows as Uprights are the vertical sections on each end of the bay. Each frame comes pre-assembled (here in Australia) and ready for easy installation. This means we have done up all the bracing and bolts so you just need to clip your beams in place … not a single nut or bolt for you to worry about!! We often get asked why our frames are bolted together and not welded, the simple answer is it’s stronger. For example if you look at the big brother of Longspan Shelving “Pallet Racking” you will not find a weld anywhere and this is a product that is Engineered and Tested to be as strong and durable as it can possibly be.

Our frames are available in 5 standard heights (900mm, 2000mm, 2500mm, 3000mm & 4000mm) and 4 depths (400mm, 600mm, 800mm & 1200mm). Our frames have pre-pressed holes every 50mm meaning that when you set you shelf heights they are adjustable in 50mm increments.

Each frame is supplied with heavy duty base plates allowing for the system to be bolted down making it super secure. The base plates have multiple pre-pressed holes allow for various anchoring points. The larger size of the base plate make the entire system more stable, kind of like having really big feet….


Longspan Beams simply click into the Upright Frames making the shelves. You will require 2 Beams for each shelf(one at the front and one at the back).

Our beams are available in 7 standard lengths (900mm, 1200mm, 1500mm, 1800mm, 2000mm, 2400mm & 3000mm). The load rating of each shelf is determined by the beam length, the shorter the beam the higher the load rating, or the longer the beam the lower the load rating.

Each beams is supplied with 2 “Safety Locking Pins” designed to stop the Beam from being dislodged from the Upright Frame



Longspan Shelving has 3 different shelf material options, timber, steel or wire. Timber Shelving is easily the most popular option as it is strong and economical. All our timber shelves are made with 18mm Particle Board (Manufactured here in Australia) and pre-cut ready for easy installation. The steel and wire option is ideal for specific environments like “fire safety” or storing products where the shelves may get wet from time to time like paints and oils.



If you’re likely to be storing heavy items we also have an option to upgrade the storage capability by including “Timber Support Bars”. These support the shelf from front to back and spread the load evenly over the beams. If you are not sure if you need these, give us a call and we can discuss the options with you.

Frame End Caps are also available to cover the exposed steel frames, these are ideal on workbenches or anywhere you may want the extra protection.

Storage Bins are an ideal accessory to Longspan Shelving Adelaide, perfect for sorting everything out and keeping organised. Pallet Racking System has an extensive range of storage solution that work perfectly with Longspan Shelving.



Bay Length: When measuring to see what bay or combination of bays are going to be the perfect fit for you there are a couple of things to consider.

The main thing to consider is that the beam length refers to the internal span of the shelf not the external dimension of the shelf. You will need to add 60mm for each frame required, this will work out to be 120mm for a “Standalone Bay” and 60mm for each “Add on Bay”

Here are a couple of examples to show you what we mean:

If you are looking for a single bay the space you have available is 2000mm wide then you will need a bay that has 1800mm beams. The external length of this bay will be 1920mm. The length of the bay is made up with the 2 frames (60mm on the left, and 60mm on the right) and the 1800mm beam length (internal shelf span).

When you are joining multiple bays together you will need to allow 120mm for the first bay, and 60mm for each additional bay. Here is another example, the same as the above example, but with 3 joining bays. In this instance the the external length of the Pallet Racking System will be about 5640mm. This is made up from the 4 Upright Frames (4x 60mm) and 3x beam lengths (3x 1800mm). The first bay, also known as the “Starter Bay”, will have 2 frames (2 x 60mm = 120mm) and each of the additional 2 bays “Add on Bays” will have 1 frame each (60mm).

Bay Height: Selecting the height of the shelving required is usually limited to the height you have available, for example if you have a space that is 2700mm from the floor to the roof then you could choice between the 2000mm high frames or the the 2500mm high frames. The 2000mm high frames would be perfect if you are storing larger items on the top shelf whereas the 2500mm high frames may allow for an extra shelf but it may require a ladder to allow you to reach the top.

Bay Depth: The depth of the shelving is usually based on the space you have available and what you will be storing on the shelf. If you’re only storing small items and have limited space, the the 400mm depth could be perfect for you. If you are storing larger, bulky items and want the extra depth and could consider the 600mm or 800mm depths. We have a really deep shelf that is 1200mm deep and this is perfect when you have access from both sides of the shelving, like in a storeroom or warehouse.


No need to panic …. This can all be a bit confusing but you don’t need to worry about a thing. We can work it all out for you and come up with the ideal bay, or combination of bays to maximise your storage area. Just give one of our branches a call, or send us a message and we will sort it all out for you…
