How to Build a Shelf (Step-by-Step Assembly)

Want to build your own shelving? Then this step by step guide will show you exactly how to do it. 

Using the 923 kit, this guide will show you how to build a shelf entirely from TubeClamp fittings and tubes. The benefits of these fittings is that unlike traditional pipe fittings that connect to tubes using a threaded connection, TubeClamp fittings slide over the tube and is secured by tightening a set grub screw on the fitting. This makes them easier, faster and more convenient to use as well as giving the advantage of disassembly. 

Your shelving structure can easily be disassembled and reassembled completely or partially, making it easier to transport, as well as adjusted, giving you the freedom to redesign your shelf with the parts. The only limit is your creativity. 

Colour options

Tubeclamp fittings and tubes comes in a galvanised steel finish which has a simple aesthetic charmHowever, we also offer a wide range of powdercoated colours and finishes (for an additional charge). To view the list of colours available, click here to view the dulux powder coating range.


As with most TubeClamp projects, you can assemble the project in any way that makes sense to you. there is no 'set' order for assembling a Tubeclamp project. However, it is recommended to start from the bottom and work your way up. This guide shows what we believe to be the easiest way to assembling this shelf. 

Tools required: 

Hex Key size B

Other materials:

Wooden/metal or other material panels for shelving

Fittings and Tubes for assembly (Or purchase them in a kit here: 923)


Assembled size: 

L 180 x W 60 x H 90 cm

Tube size: B 25NB/33.7mm  

Step 1:

Fit all of the TC131 Base Flange into the ends of the 900mm tubes. Lay them on the ground to make things easier for you while assembling.

Step 2:

Slide two TC116 Corner Middle Cross onto each of the 900mm tubes from step 1. Slide a TC128 Corner Top Cross onto the top. 

Step 3:

Attach a 600mm tube to each of the three fittings for two of the 900 posts from Step 2.

Attach the other end of the 600mm tubes to on of the other two 900mm post from Step 2. Repeat once more for the remaining post. Tighten the grub screws holding the 600mm tube, at the levels you want your shelf, securely with a hex key. 

You should have two support structures.

Step 4

Slide two TC199 Single Lug Bracket onto each 1800mm tube.

Join the two side support structures from Step 3 with two 1800mm tubes per level, for three levels as shown in the image.

- Fasten the ends of the 1800mm tubes to the TC116 Corner Middle Cross from the previous steps for the middle and bottom rungs. 

- Fasten the ends of the 1800mm tubes to the TC128 Corner Top Cross for the top rungs. 

Tighten the grub screws on the fittings securely with a hex key. At this point, the structure should be standing. Complete a final check to make sure all the screws on each fitting is tight. 

Step 5: 

You can now add shelves of your choice. Secure them by screwing them to the TC199 Single Lug Brackets.

Congratulations! You are done! You should now have a practical and durable storage/display shelf. 


You can try various alternatives, such as adding castor wheels for mobility, more shelves, less shelves, adding brace support for increased stability or changing the size of the project.
