What this grade means
Select Structural is the highest quality structural grade for softwood dimensional lumber. It allows very few natural characteristics and provides the highest design values for bending strength, stiffness, and compression. Pieces are tight-grained with minimal wane, splits, or knots.
Defects allowed
Very tight knots only, no wane, minimal slope of grain, no shake or splits
Typical uses
Engineered structures, exposed structural framing, high-load headers, long-span joists, critical structural members
Grade rules vary by species, region and grading agency. For structural work, use the grade stamp and governing code or an engineer’s specification—not appearance alone.
