This Wood Species series comes to us from guest writer Rob Wilkey, an Atlanta-based woodworker and industrial designer whose expertise is in small home goods, furniture, and large installations.

Over the next few articles, we’ll be analyzing a number of common domestic wood species. Up first:

Pine is the most abundant type of wood in North America. Dozens of species are harvested here, their colors ranging from pale yellow to light reddish brown. Although some pines can exceed 900lbf on the Janka hardness scale, most are much softer, commonly below 500lbf. Despite its softness, pine has remarkable structural stability and is generally resistant to seasonal movement. Pine is also extremely inexpensive, making it the ideal candidate for large-scale structural work, such as framing for houses.

Pine’s grain structure and working properties are largely similar across the different species. All pine is straight-grained and ring-porous, showing its growth rings as dark bands throughout the wood. Pine boards frequently contain a number of knots, which can be problematic during cutting, but the wood is otherwise very easy to work with. Despite its low density, pine isn’t highly porous and takes glues, stains, and finishes very well. While most species of pine are too soft for use outside of structural supports, the denser species are commonly used for flooring, wall panels, and furniture. The contrasting grain and abundance of knots give pine an interesting, ‘rustic’ look.
