Random Lengths

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.

The sapwood of White Oak is light in color and can range from a pale yellow-brown to a greyish-white. The heartwood may be either light brown in color or a darker brown with deep, golden tones. The distinctive coarse texture and straight grain has longer rays than Red Oak. Fast-growing Oaks, such as those grown in the South, produce wider, more prominent growth rings.

White Oak is heavy, hard, and very strong. It is worked easily, by machine or by hand, although slow-growing Oak is much easier to work than the faster growing varieties. While White Oak nails and screws well, pre-boring is advised for best results. To prevent the wood from reacting to iron, galvanized nails are recommended. Excellent results can be expected with staining, bleaching, or pickling.
