Ordering wood question

[beckhamk]

I have a question on the type of wood to be ordering.....  On Johns plans it says to get DF #2 or better.

So I gave my list to 84 lumber here in ohio and they can provide PT lumber in southern yellow pine.  The other dimmesional lumber is a mix of souther yellow pine #2 or better and spruce pine #2 or better.

So is this ok to use or should I be insisting on the DF #2 or find another supplier?

#2 SYP has higher strength values than DF so is "better"
#2 SPF has lower strength values than DF so is not "or better"
however these plans are not designed for any specific area and for unkown loads. If you are talking about floor joists then the above is probably fine. If we are talking about rafters subject to higher snow load this might need to be visited further.

The mix of SYP/SPF is for the floor joists and the outside and inside walls - So is the SPF on for the walls then? 

We are actually going with engineered trusses, so we are convered there.

Thanks for your input don!

I'd say yes, around here three or four years ago all the lumber yards carried was SPF , these days we are back to just DF for wall framing lumber.

With a truss roof you are covered I'd say.

If your floor joist could be the SYP or DF  you might be a bit better off.  In my experience the SPF stus twist and warp quicker and 'more' than DF , but all wood can go "fruit cake" on you if left uncovered and not nailed to other parts , sheathing / plates , etc.

So I guess what ever you get for lumber I'd stack it carefully on a nice flat area and cover the pile well between weekends. This assumes you are building yourself  and the build will be on weekends so relatively slow.

I'd also suggest IF that is the case you lay down two strap clamps  that would be under the pile , so you could also strap clamp the lumber together , sort of like the bands they use on the slings of lumber for shipping , this might help with  keeping the lumber some what straight.

Good luck, PEG.
