Substantial volumes of clear and nearly clear timber products are available in Douglas fir in a variety grading options and textures.

Douglas fir’s light rosy color, which darkens over time when exposed to UV rays, is set off by its remarkably straight grain pattern. The tough fiber holds fasteners well and it machines to an exceptionally smooth, glossy surface. When dry, Douglas fir retains its shape and size without shrinking, swelling, cupping, warping, bowing or twisting, and generally won’t check or show a raised grain.

Free of heart center (FOHC) is highly recommended as this allows the timber to remain straighter. Kiln drying, including Radio Frequency drying (RF), is available on nearly every timber size, insuring the optimum results on larger timber projects. Surfaced four sides (S4S), circle-sawn, band-sawn, rough-sawn and hand hewn textures are available. Pre-cut corbel end capability offers limitless decorative end patterns to set off your design with something unique and can be delivered at your door ready for construction directly from our mill.

Treated Douglas fir, for exterior exposure, is becoming more attractive due to insect and fungus resistance. We offer several treating opportunities dependent on final result expectations. Such characteristics make Douglas fir the ideal specie of choice for the most demanding projects. Clear coatings, transparent lacquer, varnishes, oils, wax, bright or subdued stains, tints or paints and enamels are all appropriate finishes.
