The majority of our lumber species are sold in both rough and milled form. Many domestic species are available in 4/4, 5/4, 8/4 thicknesses, with some up to 16/4.
All rough lumber is "Random Width - Random Length", and is sold by the board foot.
Our milled lumber in common domestic species is usually sold as S4S (Surfaced 4 Sides). S4S lumber is sold by the Lineal Foot (LF), with a LF price for each species, thickness and width.
Most exotics and specialty domestics are sold as S3S (Surfaced 3 Sides), and are sold by the board foot.
