S4S stands for “Surfaced Four Sides.” In the context of woodworking and lumber, S4S refers to a type of wood that has been precisely planed and smoothed on all four sides, resulting in a uniform and consistent surface. The process involves removing any roughness, irregularities, or imperfections from the wood, creating flat, straight, and smooth edges.
S4S lumber is commonly used in various woodworking projects and construction applications. Its ready-to-use nature saves time and effort, as it eliminates the need for further surface preparation. This makes S4S lumber highly convenient for craftsmen, builders, and DIY enthusiasts, as they can focus on creating their projects without the additional steps of planing and squaring the wood.
