Glacial Species & Grades

White Oak Superior Natural is a high-quality grade, yielding a minimum of 83-1/3% clear face cuttings and sound and better on the reverse face. Minimum size cutting sizes of 3” x 7’ or 4” x 5’. Ideal for applications requiring long, wide clear-face cuttings or multiple rips and chops. This grade allows all color variations, including mineral, sapwood, sap stain and sticker marks on either face. We grade after drying and surfacing, and against all natural drying or surfacing defects (pin knot no defect).
