S4S (Surfaced Four Sides)
S4S, or Surfaced Four Sides, refers to lumber that has been planed on all four sides to achieve a smooth and uniform thickness. This milling process enhances the appearance of the wood and prepares it for finishing and installation. S4S lumber is commonly used in applications where aesthetics are important, such as cabinetry, furniture, and trim work. At Westman Lumber Supply, we provide a selection of S4S lumber in various species and sizes, making it easy for builders and craftsmen to find the right material for their projects.
