Wondering what those lumber finish codes actually mean? Here’s a quick rundown, Twin Oak style:
• RS (Rough Sawn) – Straight from the sawmill, no smoothing. Thick, rugged texture great for rustic projects.
• S2S (Surfaced Two Sides) – Both faces planed smooth, edges left rough. Awesome if you want a clean face but DIY the final edges.
• S3S (Surfaced Three Sides) – Faces and one edge smoothed up, other edge still rough. Handy for shelves and desktops where one edge is visible.
• S4S (Surfaced Four Sides) – All faces and edges smooth, ready for joinery or finishing work!
