Common Names: Walnut, Black Walnut, Eastern Walnut

Market Availability: Usually available in 4/4 – 8/4. Limited availability in 10/4 – 16/4

Common Uses: Flooring, cabinets, furniture, mouldings, trophies, giftware

Regional Differences: Walnut from the north often shows a more uniform chocolate brown color. Walnut from the southern end of the growing range may exhibit a wider range of color with some green or purple hues

Color Specifications: Steamed, unsteamed. Nearly all walnut is steamed prior to kiln drying. Steaming darkens the sapwood through caramelization of the plant sugars in the wood fiber. Although walnut sapwood darkens considerably during steaming, after planing it will remain lighter in color than the heartwood

Grade: Walnut is graded per NHLA Walnut grade rules. These rules are generally considered to be more lenient than NHLA Standard grade rules
