The Basics of Softwood Lumber Grades
Grades of Lumber Softwood Grades are based on the American Softwood Lumber
Standard. They are broken into three classifications: Boards, Dimension Lumber, and
Timbers.
Boards are mostly for appearance such as cabinets or paneling.
Dimension Lumber represents 2 x 4’s and other light framing needs.
Timbers are commonly used for structural framing, cladding and panelling,
benchtops, flooring, decking, joinery, beams and poles.
