Grades of Softwood Lumber

Wood grading is used to rate the quality of a piece of lumber. For manufacturing purposes, the primary grading category for softwood lumber is appearance. Appearance is divided into two categories: finish and select, each of which is divided into subgrades that are identified by letters. Factors such as knots, slope, warping, and manufacturing defects are all used to determine grading. For example, a piece of lumber that is rated A Select is considered nearly perfect—with no knots or other visible defects—while a piece that is rated D Select may have some minor flaws.
