S4S stands for “surfaced on 4 sides”. Our S4S is produced in a moulder with all surface faces and edges very smooth.

Cabinet Facing (aka Face Frame) is typically surfaced S4S to 13/16" from 4/4 lumber to actual width.

Dimensional lumber is commonly S4S and labeled according to nominal size, or the size of the rough board before it was planed smooth. For example, 1x6 is actually 3/4x5-1/2. Dimensional hardwood lumber or S4S lumber is ready to be made into cabinets, furniture or trim.

Red Oak sapwood ranges from white to light brown in color. Most varieties of Red Oak heartwood will have golden, reddish tones, although some display deeper, reddish-brown tones. The wood has a coarse texture with a straight grain and shorter rays than White Oak.

Its excellent working properties have made Red Oak popular throughout American history for furniture construction and cabinetry. It machines well with moderate blunting of equipment. Red Oak holds nails and screws well, although pre-boring is recommended for best results. Red Oak is a very hard, heavy wood with good stiffness and excellent crushing strength. Red Oak stains to an attractive finish with stains.
