Western Species & Grades

Oregon White Oak Premium is an appearance and structural grade with scattered sound and unsound defects. Each Oregon White Oak Premium board yields 83-1/3% to structurally sound fiber with restrictions on larger unsound defects on the best face. The reverse face will grade out to Standard Frame or better. The natural color difference between sap and heartwood is acceptable. We grade after drying and surfacing, and against all natural drying or surfacing defects (pin knot no defect).
