Final Processing at the Precision Abrasive Planer Produces a Highly Finished Product for Our Customers  To better achieve our commitment to supply our customers with only the best value and quality products all dried lumber is routed through our  state-of-the-art sander. The sanded product allows us to offer our customers a uniform product requiring significantly less final finish work in their manufacturing process. Boards entering the two-stage sanding process receive a smooth surface on both the top and bottom faces, and are finished to a uniform thickness. Final inspection and grading are the next process.
