Douglas fir

A unique native species of North America forests, known for its strength, durability and diverse applications. It has the quality and looks of the famous Indian Himalaya species known locally as Devdar. Many Indian market places are selling Russian and New Zealand pine but Mprth American Douglas fir is unique native species and despite the fact it may share some similarities with other species but its density and strength qualities are unmatched.

The straight grained and exceptionally strong Douglas Fir tree is one of the most dominant species in the Northwest forests. After a forest fire, the tree springs to life, growing thickly in the sunshine of a newly open area.

Over the past 100 years, it has been the favorite species of silviculturists because of its fast growth and multitude of uses. Its stiffness and durability make it ideal for structural applications. It also makes a good flooring and paneling product as well as a fine trim for doors and windows.

Douglas Fir is known for its distinctive grain patterns, produced by the varying degrees of spring and summer wood in the grain. The color differences between the two range from yellowish to reddish brown. Douglas Fir flooring ages to a warm orangebrown color. Douglas Fir (Pseudotsuga menziesii) is not a true fir at all, it is a distinct species named after Archibald Menzies, a Scottish physician and naturalist who first discovered the tree on Vancouver Island in 1791, and David Douglas, the Scottish botanist who later identified the tree in the Pacific Northwest in 1826. Douglas Fir is North America’s most plentiful softwood species, accounting for one fifth of the continent’s total softwood reserves The wood of Douglas-fir varies widely in weight and strength. When lumber of high strength is needed for structural uses, selection can be improved by applying the density rule. This rule uses percentage of latewood and rate of growth as they affect density. For equivalent knot sizes, the higher density generally indicates stronger wood. Sapwood of Douglas-fir is narrow in old-growth trees but may be as much as 3 inches (7.62 cm) wide in second-growth trees of commercial size. Fairly young trees of moderate to rapid growth have reddish heartwood and are called red-fir. Very narrow-ringed wood of old trees may be yellowish brown and is known on the market as yellow-fir. The range of Douglas-fir extends from the Rocky Mountains to the Pacific coast and from Mexico to central British Columbia.

The Douglas-fir production comes from the Coast States of Oregon, Washington, and California and from the Rocky Mountain States. Douglas-fir reaches heights of 250 feet (76.20 m), with a diameter of 6 feet (1.83 m), in coastal stands that are between 200 and 800 years old. The largest intact specimen was recorded at 330 feet (100.58 m) near Littlerock Washington.

APPLICATIONS: Is structural timber- where you need strength and wt. bearging capacity- Architects dont trust anything else than Douglas Fir. And when they need appearance - no wood, no species can compete grain and beauty of Douglas Fir. Thus it is preffered in doors, windows, framing, light furniture applications.
