PT posts for beam support


Let me just double check something real quick please... I can get 6x6 PT posts that are rated for ground contact at $19.97 for an 8' length or not rated for ground contact at $15.97. These are going into galvanized simpson brackets set into concrete at the bottom. The top of the concrete footings are level with the ground. (And will have drainage put in on 3 sides)

Am I correct in assuming I don't need the ground contact and can go with the less expensive post?

The brackets should keep the wood off the ground. How many posts are we dealing with where $4.00 per post is an issue?

PT posts for beam support


It's the difference between starting this weekend or putting it off to the next weekend. There are 7 posts per beam and I'm getting 3 posts per 8' board. So I'd need 3 to build up the one beam I'm planning to build this weekend. The extra $12 is enough to put me over budget. I'm also getting the 2x10's for the beam and a box of framing nails.

Are the cheap ones structural wood or are those actually landscape timbers?

As far as I can tell the non-ground contact is treated with ACQ and the ground contact is treated with CA. Both indicate use for decks.

Lowes only has 1 6x6x8 listed at $19.95 and it's treated with ACQ and rated for ground contact.

You need special fasteners for pressure treated wood. Hot dipped galvanized or stainless steel. The wood will "eat" regular nails in a year or so.
