Just use the span tables in the IRC..treated has nothing to do with the span...only the species does.
This one is handy. :thumbsup:So I can follow the table for southern pine, US lumber?
Thanks Greg, lots of info there.http://www.southernpine.com/spantables.shtml
Anything you'd every want for SYP.
'Bout the only time we see itI don't think we have incised lumber out here.
I think that is the stuff you see the nicks all over it, right?
