Rough sawn lumber has not been planed
down to a finished look, so it generally is
closer to its nominal dimensions. In other
words, a 2x10 that is rough sawn is much
closer to 2" thick by 10" wide. It is not generally used for anything that will be visible, or even
that will remain a part of a house for any length
of time. Concrete forms often use some rough lumber. Ramps onto truck beds are
sometimes rough lumber.
We stock three basic kinds of rough sawn lumber. It is all spruce, and comes in either 1x6-16 footers, 1x8-16 footers, and 2x10-16 footers.
