Lumber

Lumber, also called timber in the United Kingdom, Australia, and New Zealand, is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building.
