Douglas Fir (Pseudotsuga menziesii) is Canada’s largest tree. It is found throughout the southern half of British Columbia. This species is one of Canada’s strongest commercial softwoods.
This species ranges in colour from light in the sapwood to yellowish-reddish-brown in the heartwood. The grain is defined and has a distinctive grain pattern when flat sawn. The wood is fine to medium texture, straight grain and non-porous.
Douglas Fir has a high bending strength, shear strength and stiffness. It is a hard species and is suitable for use where wear is a factor. The heartwood is moderately decay resistant.
This softwood lumber dries well with good dimensional stability. It machines well and is typically used to make doors, windows, structural products, ladders, flooring, staircase parts, and trusses.
