About Douglas Fir Wood

Top portion is finished with water-base finish!

Can vary in color based upon age and location of tree. Usually a light brown color with a hint of red and/or yellow, with darker growth rings. In quartersawn pieces, the grain is typically straight and plain. In flatsawn pieces, (typically seen in rotary-sliced veneers), the wood can exhibit wild grain patterns.

Typically machines well, but has a moderate blunting effect on cutters. Accepts stains, glues, and finishes well.

Named after Scottish botanist David Douglas, (though the scientific name is in honor of Archibald Menzies, who first described the tree in the 1790s). Douglas-Fir is technically not a true Fir (Abies genus), but is in its own genus: Pseudotsuga. The tree itself grows to be very large, and yields a large amount of usable lumber and veneer for plywood. It is an incredibly valuable commercial timber, widely used in construction and building purposes. The wood is very stiff and strong for its weight, and is also among the hardest and heaviest softwoods commercially available in North America. The mechanical properties listed represent the average values from four regions: coastal, interior west, interior north, and interior south.
