What does rough sawn and smooth planed mean?
Rough sawn wood has a rough saw texture and APPROXIMATE, ROUGH DIMENSIONS. It could have stick marks left during the drying process, weathering (grey or charcoal colored), and small metal banding marks where it was bundled together. Smooth planed wood has been run through a wood planer which gives it a smooth finish, similar to a 2×4 you’d find at the lumberyard. It’s milled to exact dimensions and planed on all four sides unless specified otherwise.
