Pin Oak

Pin Oak (Quercus palustris)

Common Name(s): Pin Oak Scientific Name: Quercus palustris Distribution: Eastern United States Tree Size: 50-75 ft (15-23 m) tall, 2-4 ft (.6-1.2 m) trunk diameter Average Dried Weight: 47 lbs/ft3 (760 kg/m3) Basic Specific Gravity: .58 Hardness: 1,510 lbf (6,720 N) Rupture Strength: 14,000 lbf/in2 (96,600 kPa) Elastic Strength: 1,730,000 lbf/in2 (11,900 MPa) Crushing Strength: 6,820 lbf/in2 (47.0 MPa) Shrinkage: Radial: 4.3%, Tangential: 9.5%, Volumetric: 14.5%, T/R Ratio: 2.2

Color/Appearance: Has a light to medium reddish-brown color, though there can be a fair amount of variation in color. Conversely, White Oak tends to be slightly more olive-colored, but is by no means a reliable method of determining the type of oak.

Grain/Pore: Has medium-to-large pores and a fairly coarse grain.

Endgrain: Ring-porous; 2-4 rows of large, exclusively solitary earlywood pores, numerous small latewood pores in radial arrangement; tyloses absent; growth rings distinct; rays large and visible without lens; apotracheal parenchyma diffuse-in-aggregates (short lines between rays).

Durability: Red oaks such as Pin Oak do not have the level of decay and rot resistance that White Oaks possess. Durability should be considered minimal.

Workability: Easy to glue, and takes stain and finishes very well.

Scent: Has a tell-tale smell that is common to most oaks. Most find it appealing.

Safety: Although severe reactions are quite uncommon, oak has been reported as a sensitizer. Usually most common reactions simply include eye and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Price/Availability: Slightly less expensive than White Oak, Red Oak is in good/sustainable supply and is moderately priced. Thicker 8/4 planks, or quartersawn boards are slightly more expensive per board foot.

Comments: Pin Oak falls into the red oak group, and shares many of the same traits as Red Oak (Quercus rubra). Red Oak, along with its brother White Oak, are commonly used domestic lumber species. Hard, strong, and moderately priced, Red Oak presents an exceptional value to woodworkers—which explains why it is so widely used in cabinet and furniture making.
