Douglas-fir Timbers

Humboldt Sawmill Douglas-fir timbers are available from 4” x 6” up to 12” x 24”, and lengths up to 24 feet, with rough green and surfaced four sides (S4S). Humboldt Sawmill Douglas-fir timbers are graded and stamped. 

Douglas-fir timbers are prized for their strength, span rating, and superior workability. Douglas-fir timbers may be used in structural applications as well as interior finishing such as exposed posts and beams. 

Humboldt Sawmill is the leading supplier of Forest Stewardship Council® (FSC® C013133) certified redwood and Douglas-fir lumber, timbers, and uppers. Logs are sourced from 450,000 acres of company-owned timberlands in northern California. 

Finished goods are manufactured at company-owned sawmills in Scotia and Ukiah, California and available direct from the mills, as well as through company-owned distribution locations throughout the Western U.S. Customer orders ship via rail and truck.
