Plants which saw aspen lumber for their own use rarely apply standard grades in sorting the lumber. They usually separate the "usable" from the "cull" lumber, basing their grade breakdown upon the minimum quality acceptable in their manufacturing process. Manufacturers who use only certain grades of aspen lumber, and who buy it on the open market, have been unable to locate sources from which graded aspen lumber is …
