Our area suppiers don’t seem to stock
0.060 retention pressure treated posts.
They are all 0.040.
How critical is this detail for fence posts and pole barn posts ?
I’m needing to bury 12′ tall 6×6 beams at 4′ depths.
Will use gravel instead of concrete for fill.

.060 is always special order at my lumber yard..
and i alway order an extra two or three (about 10%)..
this allows for the bows.. and the oops .. and the ""wish i had one more post right here...""
but .060 is code for foundation work.. for anything structural buried in the ground..
decks , fences.. we use .040.. but habitable spaces or poles for pole barns.. you should use the .060
also.. buy the 16 ft. poles...you got 4 ft bury.. a foot of grade..
only leaves 7 ft. ....IF your site is dead level.. we usually wind up with 2.5 to 3 ft cut-offs...
*For fences and pole barns in my area, .40 is perfectly ok. Of course, we only have to go down 12" for frost line, but we go 24" to 36" for structural integrity and strength. Check the local codes to determine what THEY say about the allowance of .40 pt wood. Also, the species of wood will be a very imortant factor. PT southern yellow pine is standard here, and we have not had anywhere near the problems that others on this board speak of.For living spaces here, 12" x 12" posts are code for foundations. These are always .60 rated. .60 for anything smaller than a 12" x 12" here is for direct water contact (marine use), and is very hard to get. Like Mike said, it's a special order item.James "Finally Got Some Rain" DuHamel
*james... SYP is standard here too for PT...always has been.. the only thing that ain't is ""landscape timbers"""Special Order means two days..the treatment plant is two miles from my lumber yard
*Portland OR metro area:.60 ppf retention Hem Fir commonly available in 6x6, 8x8 and 1/2" and 3/4" plywood. Other dimensional should be available with a couple of days lead also.I assume you mean real lumber yards when you talk about suppliers, not ignoramuses at home box.joe d
*yeh.. real lumber yards..spent a few unpleasant hours at HD the other night..HAD to buy some of their Mills Pride Cab'ts..i'll work my way out of doing that again real soon...
*Mike,Ugh. That Mill's Pride knockdown stuff is real garbage. I had the unfortunate job of doing up a doctors office in that junk this spring..60 SYP is special order (less than a week) around here. Not too many folks use it. Just the smart ones.Steve
*Hey Mike,Treatment plant here is a local outfit, but believe it or not, they don't do .60 These have to come from out of state (or at least that's where the lumberyard gets them). Takes about 3 to 4 days.How come the west coast seems to have an over abundance of hem fir PT, and the south and east coast have SYP? Do the lumber mills out west refuse to use other products than what they produce? Heck, half of what is produced here is shipped elsewhere. We get a lot of stuffed shipped in here too. Go figure... Louisiana Pacific has a wafer board plant right in my back yard. Can't buy their product here though. Lumberyards carry Georgia Pacific and Weyerhauser wafer board. Seems like a shame.Oh well....James
*Mills Pride???....You've got 'splanin' to do Lucy!!! Jeff
*I was wrong, I just called two of my local yards and they stock .60 treated 6x6's in 12' and longer lengths for the plethora of pole barns that get built around here.Steve
*Alan, Mike. forgive the nit picking: that should be 0,40 and 0.60 lbs per cubic foot. I've never had any trouble geting 0.60 but it has to be special ordered. It is not a stocked item...at least with the lumber yerds I deal with. GeneL.
*no gene, you're not forgiven.. post a joke in the shed and i'll think about it..(the abject humiliation of misplacing my decimal points in public is too much to bear).. for want of a nail the kingdom was lost....
