Douglas Fir (Pseudotsuga menziesii) is used for building and construction purposes because of its high strength, stiffness and durability. The lumber is usually kiln dried to the customer’s specifications to improve strength, to enhance appearance, to inhibit natural staining, and to increase resistance to decay and insects.
Although it is considered a softwood, the high strength properties of Douglas Fir enables it to be used as a substitute in many applications where hardwoods are normally used.
Its resistance to corrosion makes it the lumber of choice for heavy timber applications such as:
· Flooring
· Warehouse construction
· Doors and windows
· Pilings
· Railway ties
· Laminated beams
· Trim, moldings and joinery
· Plywood
· Ship building
· Furniture
