Surface Textures
Saw Textured The saw textured surface, obtained during the milling process which uses either circular or band saws, is present on all four sides.
Rougher Headed The lumber receives its texture from a milling process which uses roughened planer knives. The rough texture is clearly visible on all four sides.
Surfaced Four Sides (S4S) The smooth surface on all four sides presents a uniformly sized product with a high quality appearance. Sizes from 2×4 (51mm x 102mm) up to 6×6 in. (152mm x 152mm) are generally available. Larger sizes are produced on special orders.
