Glacial Species & Grades

Walnut FAS/1F is our highest-yielding grade, yielding a 83-1/3% clear-face cutting and 66-2/3% on the back. Minimum cutting sizes of 3” x 6’ or 4” x 3’. NWH pulls this grade higher than typical NHLA standards and is steamed to enhance the chocolate brown heartwood and darken the sapwood. The minimum heartwood is 85/0 on the better face or 50/85 if not on the grade face. The 6’ and 7’ boards are graded for clear face cuttings and not defect graded as NHLA allows. Ideal for applications requiring long, wide clear-face cuttings or multiple rips and chops. We grade after drying and surfacing, and against all natural drying or surfacing defects (pin knot no defect).
