What size treated pine for bench seat?

[Redboy65]

G'day, I'm building an outdoor bench seat that will be under cover of a third floor outdoor deck/balcony BUT very close to the ocean (Phillip Island) - therefore exposed to the elements. It will get wet during rain periods. I'm going to be using Spotted Gum as the cladding/outside of the bench seat and treated pine for the frame (as it needs to withstand the elements). Question I have is do I use 90x35 or 90x45 treated pine for the frame? There is an obvious price difference between the two sizes and I need to reduce my overall cost BUT also need to ensure that the bench seat is going to be sturdy and strong. Any help appreciated!

Cheers, Redboy65

Hi @Redboy65,

Nice work! 

Your frame looks nice and sturdy, the natural colour of the decking looks fantastic and you've got some nice tight mitres that give it a clean finish.

I can't wait to see if finished once that pesky weather holds out and you can finish up. 

Thank you for sharing.
