I have tow reasons for skepticism. !) a
small landing I built 8 years ago is suffering splits and in general looks terrible. Edges were looked antique.barn boards.
2) In replacing the bad parts and also beefing up the frame, I found a cull at HD, a 2 x8 board with a break. It was long enough for what I needed, but I notice that the wood inside looks weak and untouched by the treatment.. Shouldn't pressure treated be better quality than this? How to select good pieces?
