Grading Options for Western Hemlock 'Pulpwood' Logs from Southeastern Alaska

摘要

Properties and grade yield are estimated for structural lumber produced from No.3, No. 4, and low-end No. 2 grade western hemlock logs of the type previously used primarily for the production of pulp chips. Estimates are given for production in the Structural Framing. Machine Stress Rating, and Laminating Stock grading systems. The information shows that significant amounts of higher grade structural lumber can be produced from these lower grade logs.
