Douglas Fir 4x4 Timber

4x4 Douglas Fir timber, free of heart center (FOHC), available 8 ft to 20 ft in even lengths — full sawn rough, or surfaced to S4S.

Our Douglas Fir timbers are cut primarily from old growth logs, and the vast majority grade out as Dense — at least six growth rings per inch. Many come from salvage logging: old growth trees already brought down by storms. They carry little to no sapwood, so they age to the uniform, rich tan-brown heartwood Douglas Fir is known for. Brashy second-growth fir is simply not the same timber.

Because they are free of the pith, FOHC timbers move far less than heart-center stock — markedly less warping, twisting, checking and splitting as they dry and settle. Ours air dry for several months before final surfacing, which holds colour and grain far better than kiln drying and keeps checking down.

Grade stamped on one end: roughly 70% Select Structural, 30% No. 1 Structural, graded by the Pacific Lumber Inspection Bureau (PLIB). Douglas Fir has the highest strength-to-weight ratio of any wood species on the planet.
