Superior is our top grade. Both faces are graded with care by our expert lumber graders. Superior is three-sides clear and better, predominantly four-sides clear. The beech is steamed to give the material a warm uniform color. No color selection is made, meaning you will find both sap and heartwood in this grade. Superior Color has no restriction on the darker colored heartwood. This is a great grade where long and wide clear cuttings are required, and color variations are not a problem.
