Is Douglas fir a redwood?

Like redwood, Douglas fir is a coniferous tree, and the wood is soft but structurally stable. It has a yellowish-white hue that darkens to orange as you approach the heartwood. It lacks any of the pest-resistant oils found in redwood or cedar and has a shorter outdoor lifespan than either of these species.

Both Redwood lumber and Douglas fir lumber are straight grained and, therefore, very sturdy. They are highly resistant to decay and are extremely stable. Structurally Douglas fir lumber is stronger than Redwood lumber, and perhaps that is why it is used more frequently for preparing frames of building structures.
