\nWood from North America is marketed as “Oregon Pine”. Of course, it is NOT a pine tree. The term “Douglas fir” used there is also incorrect, as it is not a fir tree. These woods, if from primary growth, are very fine-grained and highly valued. The domestic origins are coarser-grained and, with the exception of the earth stem cuttings, significantly knottier than the North American product.<\/p>\n
Wooden picture:<\/h5>\n
Sapwood narrow, light with a clear transition to the heartwood. Heartwood reddish brown, darkening. Latewood darker, sharply contrasted on both sides to the earlywood, veins or streaks are more contrasting than larch. Resin channels present, but overall significantly less resinous than European larch. Decorative.<\/p>\n
Properties:<\/h5>\n
The specific weight is given as an average of 0.59 t\/m3<\/sup> at a wood moisture content of 12%. Moderate shrinkage, the tangential shrinkage is 7.3%, the radial shrinkage 4.4%. Drying should be slow if resin leakage is to be avoided. Only slight tendency to tear and twist. Douglas fir wood is aromatic when freshly processed and easy to work with all tools. Easy to stain and paint. General construction timber for interior and exterior use, laminated as window timber, stage flooring, exterior cladding, gardening and landscaping, bench supports.<\/p>\n Larch and pine<\/p>\n <\/p>\n
\nBrinell hardness: 20 (comparable to pine and larch), modulus of elasticity: 12,000 – 12,500 N\/mm2<\/sup>.
\nHeartwood with limited weather resistance (durability class 3).<\/p>\nUse:<\/h5>\n
