Douglas Fir Lumber

Douglas Fir lumber is a popular and versatile softwood known for its strength, durability, and attractive appearance. It is derived from the Douglas Fir tree, which is native to North America and commonly found in the western parts of the United States and Canada. The lumber is widely used in construction, carpentry, and woodworking projects due to its excellent structural properties and aesthetic appeal.

Color/Appearance

Douglas Fir has a light reddish-brown to yellowish-brown color with a prominent grain pattern. The sapwood is usually lighter in color and may be nearly white.

Grain/Texture

The grain of Douglas Fir lumber is typically straight and can occasionally have an interlocked or wavy pattern. The texture is medium to coarse, with a relatively uniform and fine texture.

Rot Resistance

Douglas Fir lumber is moderately resistant to decay and rot. However, it is still recommended to apply appropriate protective finishes or use pressure-treated lumber for outdoor applications.

Workability

Douglas Fir is relatively easy to work with both hand and machine tools. It has good machining properties, but care must be taken to avoid tearout due to its sometimes interlocked grain. It nails, screws, and glues well and can be stained and finished easily.

Odor

Douglas Fir has a distinct and pleasant resinous odor when freshly cut.

Allergies/Toxicity

There are no known allergenic or toxic properties associated with Douglas Fir.

Pricing/Availability
