Special designations are used with certain species, such as “all-heart redwood.” Not all grades are available. Included is wood found in casing, base trim, and paneling. The stud lumber grade refers specifically to any lumber sized from 2″x2″ to 4″x18″. Wane allowances are generous in Dimension because wane has very little effect on strength. Softwood is any wood that comes from an evergreen tree. Though light framing lumber is classified in the same size range as structural light framing, the applications are slightly different.
