Question Landscape Timbers?

What is the purpose, or intended use, of Landscape Timbers that are labeled "Not Suitable For Ground Contact" ?
I have the chance to by quite a few at a good price?

The timbers only have a small portion of ACQ in them, and aren't really pressure treated as normal wood is. They are basically dipped in preservative at best, with hopes it will soak in. A good deal on the timbers is only as good as the long range intent. I use them for terrace rows for my wife's garden area. After a few years they are rotted, but the dirt has been held at bay and the terraces stay pretty well after I remove them, crowning a little, but not much.

A large part of the problem with buying ACQ PT lumber is that when manufacturers were forced to switch to ACQ their costs went up significantly. ACQ uses more copper than CCA did. Copper is expensive. Hence, the minimally (.25 psf) treated stuff you see at the big boxes.

The big box stores are going to stock what they can sell. Most shoppers see "pressure treated" and that's good enough for them. The same buyers would more than likely balk at the price for a ground contact or marine grade timber.

I you aren't using the timbers in a structural application, go for it. They'll last in ground contact for years.
