Douglas Fir

January 25th, 2009

Douglas Fir is a very popular softwood species due to its strength and versatility. We stock both timber from North America and Europe.
 
Whilst the two sources are of the same botanical species, they vary somewhat due to the climates in which they are grown. Stock from North America is slower growing (although the best ‘old-growth’ trees in America which used to be imported have Government environmental restrictions). It is mainly imported in grade #2 / 3 clears 85 / 15 which results in a small knot-content and we also have 2″ x 4″ & 2″ x 5″ in vertical-grain if required for doors etc.
 
Thicknesses kiln dried are 1″, 1½”, 2″, 2½”, 3″ & 4″. Also 6″ thick just heat-treated for import regulations. Widths in packs are random 4″ - 12″. Lengths; mainly 7′ - 16′ but can be longer.
 
French and UK grown Douglas Fir is also offered in ‘construction’ grades and mainly used for exterior joinery (if preservative treated) or roof trusses etc.
