Lumber or timber is a term used to describe wood, either standing or that has been processed for use — from the time trees are felled, to its end product as a material suitable for industrial use — as structural  material for construction or wood pulp for paper production. In the U.K. and Australia, "timber" is a term also used for sawn wood products (that is, boards), whereas generally in the United States and Canada, the product of timber cut into boards is referred to as lumber. In the United States and Canada sawn wood products of five inches (127 millimeters) (nominal size) diameter or greater are sometimes called "timbers". Lumber is supplied either rough or finished. Rough lumber is the raw material for furniture making and other items requiring additional cutting and shaping. It is available in many species, usually hardwoods. Finished lumber is supplied in standard sizes, mostly for the construction industry, and is primarily one of a few coniferous (needle-bearing) species such as pine, cedar, hemlock, fir or spruce.
