What timber for outdoor plant stand?

[minhletn]

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?

The screening is a Special Order, but what about using the 66 x 19mm 0.9m Square Cypress Pine Fence Pickets?
