Physical Structure
Compared with European redwood, it is some 60 per cent stiffer, 40 per cent harder and more resistant to suddenly applied loads, and 30 per cent stronger in bending and in compression along the grain
Durability
Moderately durable
Drying
Imported ‘Douglas Fir’ is not a difficult timber to dry on arrival in this country or in Europe, because the moisture content has already been reduced prior to shipment with some selecting out of degraded boards. Drying degrade is generally confined to surface checking, splitting and loosening of knots, and splitting in the vicinity of knots. Accordingly, stock from trees grown in the UK and in Europe when dried from the green state, needs care, particularly because of the generally higher preponderance of knots which are hard, often loose, and which encourage more wavy grain than in imported stock
Moisture Content
14 – 16% (+/- 1 – 2%)
Working Qualities
This all-purpose timber works easily with hand and machine tools, being tough, strong, moderately hard, resilient straight grain and decorative appearance. Takes screws and nails moderately well with good staining and painting properties
