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.

Southeast Alaska has 11.2 million acres of forest land, of which 4.9 million acres are considered commercial. This commercial acreage supports 166 billion board feet of sawtimber. These primarily old-growth stands of Sitka spruce and western hemlock are supporting a growing wood products industry that ranks first in the southeast economy and third in the State. This report summarizes current knowledge of the timber resource (areas, volumes, growth, mortality, quality, productivity, and trends) from the initial inventory, a partial remeasurement, and a second inventory now in progress. Historical data of wood products use, output, value, and markets are given and discussed. The report gives sources for much published and unpublished information for those who need to pursue these subjects more completely.

Based on an in-grade testing program, the Ketchikan Wood Technology Center has registered three proprietary grademarks for Alaska species of hemlock (Tsuga heteraphylla (Raf.) Sarg.), yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach), and spruce (combined Sitka spruce [Picea sitchensis (Bong.) Carr.] and white spruce [Picea glauca (Moench) Voss]). The Ketchikan Wood Technology Center conducted tests to establish glulam beam manufacturing specifications. In conjunction with this program, there is a need to measure the market for glulam beams in Alaska. The purpose of this research was to compare Alaska residential builder adoption rates of glulam beams and other engineered wood products to those of the continental United States. The results showed that a higher percentage of Alaska builders use glulam beams compared with builders in the rest of the United States.
