Lumber Identification

I bought a large amount of dimensional lumber that has been stored in a dry barn for many years.

About 1/2 the lumber looks to be "treated" ---slight green appearance----but no end tags are attached and they were stored different stack. The owners widow said some was treated.

Some boards have "use above ground" stamped on them, so I am assuming they are the treated.

I am in the process of building a deck , and would like to use treated for joist stabilization (blocking) and other bracing.

Is there any way to confirm what lumber is treated ?

Often making a fresh cut in the lumber will give you a better idea. Not all PT lumber is rated for ground burial, some is just for above grade. If I had any doubts, I'd buy new PT and save the old lumber for another project that doesn't see as much weather ..... to be on the safe side.

Yes--most of the landscape timbers sold in my area, have an end tag that says "Not Suitable For Ground Contact"
Wonder how many people realize this when they border landscape plants!!
What are the good for?????
