Treated lumber has been available since the 1930s. It has proven itself to be the material of choice for outdoor building and is an excellent and affordable structural material. Treated is used for the understructure of virtually all decks (treated, cedar or alternative topped). Johns Lumber stocks a variety of dimensions from 1x6, 1x8, 2x4, 2x6, 2x8, 2x10, 2x12, 4x4, 4x6 and 6x6. Most popular lengths are stocked.
