#2 Common: When appearance is of moderate concern, this construction grade will contain moderate sized knots (occasionally unsound) and can have a considerable amount of wane. Keep in mind, that with the introduction of Prime grades, #2 Common no longer contains some of the better grades that used to be included.
#1 Common: When appearance becomes more of a factor, #1 Common will contain smaller, fewer, sound, tight knots and have less wane than found in #2 Common. Keep in mind, that with the introduction of Prime grades, #1 Common no longer contains some of the better grades that used to be included.
Decking Grades
Standard: When appearance is of moderate concern, this decking grade will contain larger, more frequent knots, but because it is primarily designed for decking, it is virtually wane-free.
Premium: When appearance becomes more of a factor, this decking grade will contain far fewer and much smaller knots than Standard and is also virtually wane-free.
