Hi all,
Which timber would I need to build something like this picture? It’s to be used outside and probably cheaper to buy instead of making but DIY allows us to customise the size to fit our space
The frame is thin so I’m not sure treated pine or hardwood dresser can be used?
Can I used hardwood like 30x12 and 32x32 DAR Tasmanian oak? Are they strong enough to support multiple plant pots like the pic? If yes do I need any specific oil or stain to use them outside?
Hi @minhletn,
You could use Tasmanian Oak, though keep in mind it’s a relatively soft hardwood and may not hold up as well outdoors compared to other options. If you go this route, you'll definitely need to treat it with a high-quality outdoor oil or water-proof varnish regularly to prevent moisture damage, as Tasmanian Oak isn’t naturally resistant to decay.
For a project like this that will hold plant pots and be exposed to the elements, treated pine or hardwood like Merbau might be better choices. They’re more durable outdoors and can handle the weight of the pots. If you’re set on using the thinner frame design, make sure to reinforce the joints well.
Here's a rendering of what it could look like using 42 x 19mm 2.7m Pre-Oiled Merbau Solid Screening.
Please let me know if you have any questions.

Hello @minhletn
If you are using the 42 x 19mm 2.7m Pre-Oiled Merbau Solid Screening or a Merbau timber with a thickness of 19mm, I suggest using Zenith 10G x 35mm Galvanised Type 17 Wafer Head Timber Screws - 50 Pack to anchor them together. Just keep in mind that when joining two pieces of timber together the screw you are using can't be greater than the thickness of the two joined timber pieces. I also suggest having a look at this guide - How to choose the right screw for the job by @Adam_W.

Hi @minhletn
Please note that the pre-oiled Merbau might still be sweating tannins. If you don't wish to use the timber prep/cleaner, you'll need to let the timber weather for 6 to 12 weeks out in the sun while the tannins leach out of the wood. To eliminate the waiting time, you'll need to use the timber prep/cleaner. Just keep in mind that if you choose to let the timber weather out, to keep it in a place where you don't mind the ground getting stained with tannins.
If you need further assistance, please let us know.

Yes, you can @minhletn.
I used those Cypress timbers on a plant stand several years ago and they've held up exceptionally well in the weather, even without seasonal oiling or any protection.
