Douglas trees reach a height of 40 to 60 meters, maximum 90 meters. The straight cylindrical branch-free trunk is on average 20 meters long and has a diameter of 1.0 – 2.0 meters. When fresh, Douglas wood usually has a light yellow-brown colour that changes over time to a beautiful orange-ish yellow-brown in light and air. The whitish sapwood is a maximum of 40-55 mm on old, thick trees and 70-80 mm wide on younger plantings. Depending on the growing area, not only the colour but also the density and strength are variable. Douglas wood is resinous, so greasy spots or stripes can sometimes be seen on the planed surface. Resin-filled cavities running along the growth rings also occur. The Douglas wood grown in Europe is comparable in appearance and properties to the second growth from North America. Other names for Douglas wood include Doeglas, Douglas Fir, Oregon, Oregon Pine.
Douglas wood for indoor and outdoor
Douglas wood is suitable for many applications, thanks to the favourable strength properties and the large dimensions in which it is for sale. In construction both for interior and exterior work, interior and exterior panelling, pergolas and fences. Heavy beams are used, among other things, for load-bearing structures. Since Douglas wood is quite resistant to acids, it is also used for barrels and vats for the chemical industry. Western European Douglas wood is used for all kinds of posts (fencing posts, tree posts, bedrock posts, piles). The sawn timber is used as sheet piling, for both squared and unsquared gunwales (overlapping parts of facade cladding) and also for joists, beams and purlins. The processing of Douglas wood with hand tools is not easy. Machining presents few difficulties if sharp tools are used. When finishing the surface of Douglas wood, pre-treatment is required. With polyester-based finishing agents, natural drying and film formation can be prevented.
