Description
Timber
Lumber, also known as timber, is wood that has been processed into
beams and planks, a stage in the process of wood production. Lumber
is mainly used for structural purposes but has many other uses as
well.
Lumber may be supplied either rough-sawn, or surfaced on one or
more of its faces. Besides pulpwood, rough lumber is the raw
material for furniture-making, and manufacture of other items
requiring cutting and shaping. It is available in many species,
including hardwoods and softwoods, such as white pine and red pine,
because of their low cost.
Finished lumber is supplied in standard sizes, mostly for the
construction industry primarily softwood, from coniferous species,
including pine, fir and spruce (collectively spruce-pine-fir),
cedar, and hemlock, but also some hardwood, for high-grade
flooring. It is more commonly made from softwood than hardwoods,
and *0% of lumber comes from softwood.
