Timber

Lumber, also called timber or fine wood in the United Kingdom, Australia, and New Zealand, is wood that has been processed into uniform and useful sizes, including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing. Lumber has many uses beyond home building. In some parts of the world, including the United States and Canada, the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut.
