How to calculate posts and bearers for a deck?

[felipenm]

Hey there!

I am thinking about building a DIY deck and I put together this decking design. I am now working on the decking frame plan. I know that for the posts it is better to use H4 treated and the bearers and joists can use H3 treated. As for the joists' spacing, I know that I should be spacing them no more than 450mm. Now, I've done some research and I can't get my head around those span tables to decide how many posts I need and the spacing between bearers. Does anyone out there would be able to help me with that?

Your help is much appreciated.

Thanks

Felipe

That attachment method would be fine, @felipenm. Just ensure you bolt or screw through the timber to secure it.

Thanks. Do you recommend any bolt or screw for this type of work?

Galvanised bolts would be the way to go, @felipenm. Just select some that are long enough to pass through the timbers.
