Hi

I was wanting know what size joist i have to use to span 700-800mm. I was wanting to use treated pine. can i get away with using 90x45mm H3.

Cheers

No Probs.

F7 TP is typically spec'd for up to 1200mm span as a joist

Hope this helps

Latest span table for F5 H3 treated pine used in single span for decking says
90 x 45 is good for 1100mm Single span
90 x 45 is good for 1300 continuos span ( over 3 or more supports)
