What is rough cut lumber and how is it different from finished lumber?

Rough cut lumber refers to wood that has been cut from a log, but has not undergone any further processing or finishing. This type of lumber is often used for construction and building projects, where the wood will be covered or hidden from view. Rough cut lumber can be made from a variety of tree species, including hardwoods and softwoods, and is typically less expensive than finished lumber.
