Douglas-fir (Pseudotsuga menziesii)
Family: Pinaceae Common names: Blue Douglas-fir, British Columbia pine, British Columbian pine, Coast Douglas-fir, Colorado Douglas-fir, Colorado pino real, Colorado real, Columbian Pine, Douglas fir, Douglas spruce, Douglas-fir, Douglas-fir (Coast), Inland Douglas-fir, Interior Douglas-fir, Oregon Douglas-fir, Oregon pine, Puget Sound pine, Red fir, Rocky Mountain Douglas-fir, Yellow fir Distributed in: Canada, Mexico, United States (Central America, North America) Distribution overview: The growth range of Douglas fir includes Alberta, British Columbia, Arizona, California, Colorado, Idaho, Minnesota, Montana, New Mexico, Nevada, New York, Oregon, Texas, Utah, Washington, and Wyoming. Coast Douglas-fir occurs in pure stands of vast forests on moist, well drained soils. Rocky Mountain Douglas-fir may occur in pure stands or mixed coniferous forests, and thrive mainly on rocky soils of mountain slopes. Douglas-fir has also been introduced to other regions in the world, including Great Britain, Ireland, France, Belgium, Germany, New Zealand, and Australia as a source of timber. Common uses: Agricultural implements, Beams, Boat building (general), Boat building: decking, Boat building: framing, Boat building: masts, Boxes and crates, Bridge construction, Building construction, Building materials, Cabin construction, Cabinetmaking, Casks, Concrete formwork, Construction, Cooperages, Core Stock, Decorative veneer, Domestic flooring, Factory construction, Factory flooring, Figured veneer, Flooring, Form work, Foundation posts, Framing, Furniture, Heavy construction, Interior construction, Interior trim, Joinery (external): ground contact, Joinery, Joists, Ladders, Light construction, Lock gates, Marine construction, Millwork, Mine timbers, Packing cases, Paneling, Parquet flooring, Pile-driver cushions, Piling, Plain veneer, Plywood, Poles, Porch columns, Posts, Pulp/Paper products, Railroad cars, Railroad ties, Rough construction, Sporting Goods, Structural plywood, Structural work, Studs, Sub-flooring, Utility crossarms, Utility plywood, Vats, Vehicle parts, Veneer, Warehouse construction, Wharf construction Product sources: Supplies of Douglas-fir are adequate since the species grows rapidly, and its growth range extends over a wide area in North America. It is usually priced in the medium to lower range. Remarkably knot-free, strong, and light, Douglas-fir is considered to be one of the best known softwood timbers. Environment profile: Widespread, abundant, and globally secure Tree size: Trunk diameter is 150-200 cm
Colors: the heart isYellow, Yellow to golden-yellow to orangeand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureUniformand the lusterMedium
Natural durability: Very durable, Very little natural resistance Odor: No distinctive taste Kiln Schedules: UK=K US=T13C4S/T11D3S Kiln Drying Rate: Very slow Drying Defects: Slight twist/warp, Splitting Ease of Drying: Variable Tree Identification: Bole/stem form is straight
Comments: Douglas-Fir is reported to produce the most, in total volume, of timber, lumber, and plywood for veneerGeneral finishing qualities are rated as good Generally stron and hard Lumber from old trees is valuable because it is free of knots Blunting Effect: Moderate Boring: Very good results Carving: Fairly Easy to Very Easy Cutting Resistance: Level of difficulty depends on percentage of latewood Gluing: Very good properties Mortising: Moderately easy to mortise Moulding: Moulding ease is moderate Movement in Service: Moulding ease is moderate Nailing: Pre-Boring Recommended, Very Good to Excellent Planing: Very Good to Excellent Resistance to Abrasion: Peel and slice easily because they are typically well-formed and not very hard Resistance to Impregnation: Sapwood is resistant Resistance to Splitting: Satisfactory Response to hand tools: Variable qualities Routing recessing: Fairly Easy to Very Easy
Sanding: Very Good to Excellent Results Veneering qualities: Veneers easily, Veneers moderately easy Steam bending: Moderate
Screwing: Screws hold very well, Very Good to Excellent Results; Turning: Very good
Painting: Satisfactory; Polishing: Satisfactory; Staining: Very Good to Excellent; Varnishing: Satisfactory;
