Built several items out of treated lumber from Lowe's ; board fence for my daughter and a picket fence at my home. At least half the wood warped and twisted to some degree.. Even 4 by 4 s in concrete were curved. Hard to dig up to bring back.
Did take down treated and returned.
Never buy that junk again. The lumber co. is not drying the wood nor is Lowe's concerned about quality.
Gonzales la. lowes' and Baton rouge la. lowe's from jan 2012 to present.
Had better luck with home depot treated lumber.
