How to attach wire trellis onto a Colorbond fence and shed?

Hi Team


I have a corner of a garden where I plan on growing climbing plants to hide our fence as well as our shed.


I am looking at installing wire trellis so that my plants can grow upwards. 

I am assuming I need to use some kind of wood and attach it to the fence, and then drill eye hooks down the wood and then I can feed the wire into it and run it down the fence and shed.


I want to make sure i bring the wire forward of the fence so that the heat of the metal doesn’t burn the leaves.


I guess my main questions are


1. what type of wood do I need to use?  don’t want termites or the wood rotting from the water.
2. how would I go about attaching the wood to the fence?  The fence I am guessing I would attach it to the vertical piers, but what type of screws or system would I use to attach?

3. How would I do about attaching this to the shed?  Unlike the fence the shed doesn’t have piers.


thank you!!

Hello @jono1983


Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thank you for sharing your question about how to attach wire trellis to your Colorbond fence and shed.


I suggest using Porta 40 x 18mm 2.4m Treated Pine DAR to be attached from post to post. In order to increase the distance between the timber and the Colorbond fence, you can use Carinya 50 x 50 x 20 x 4mm Galvanised Angle Bracket - 4 Pack to be placed on the end of each long timber piece. Painting the timber piece will add an extra layer of protection and will make it last longer. I recommend using Buildex 14 - 10 x 25mm Climaseal Hex Head With Seal Metal Cladding Tek Screws to attach the angle brackets to the Colorbond post. You then attach the timber to the angle brackets and then attach the trellis to the long pieces of timber.


Attaching to the shed will be a bit trickier. I suggest pre-drilling your mounting holes so that you will know where the angle bracket will be attached. I suggest putting a timber backing on the inside wall of the shed for you to drill in. This will then hold the angle bracket in place in order for you to attach the long timber piece. I've placed a sketch below for you to see how it will be attached. 


If the distance I've recommended is too far, you can attach the timber directly onto the fence post but the gap will be around 20mm only. Usually, screws are drilled into the top of the Colorbond fence and the wire is simply wound onto it. If you go with my recommendation, It's important that you use a lightweight trellis only or wire mesh so that the long timber piece will not droop or sag. It sounds like a great project for climbing plants. Any updates you can provide while building it would be much appreciated.
