Surfaced American Walnut Hardwood

We can surface your American Walnut Hardwood order in two different ways.

  • S2S (Surfaced Two Sides) – The American Walnut Wood board(s) will be surfaced on both sides/faces to a smooth finish. Both edges remain rough and will need to be straightened by the customer or woodworker.
  • S4S (Surfaced Four Sides) – The American Walnut Wood Board(s) will be surfaced on all four sides to a smooth finish. The board will be straight and ready for glue up.

Light sanding on surfaced sides/faces will be required by the customer or woodworker once the project is near complete.

Additional lead time may be required if your order requires surfacing.
