S4S Finish Lumber

S4S (Surfaced Four Sides)

S4S is a dimension product typically sold to millwork companies, and cabinet manufacturers. Every S4S board goes through a rigorous selection and state-of-the-art manufacturing process.

First, the proper lumber is selected for superior qualities such as grade, texture, and color consistency. Then, all the boards are surfaced to a hit and miss thickness on a Planer. This operation virtually eliminates cup and minor surface checking. The boards are then scanned for width and defect and then gang-ripped on a  Moving Blade Rip Saw.

Next, the boards are optimized for length and precision double end trimmed on a Optimizing Saw System.

Finally, the boards are run through a high-speed molder that gives the finest molded S4S finish available at Windsor Plywood.
