Wood of the oaks in the red oak group is similar to that of the white oaks. A major difference is that red oaks are extremely porous, and therefore not suitable for such uses as tight cooperage. The wood is heavy, hard, stiff, and has high shock resistance. It undergoes large shrinkage during seasoning. It is above average in all machining operations except sharpening. The heartwood is low in decay resistance. Wood of red oaks is used for flooring, slack cooperage, furniture, millwork, boxes, crates, caskets, timbers, handles, coffins, pallets, agricultural implements, boats, and woodenware. The hardness and resistance to wear of red oak, plus its beauty, make it preferred for flooring and residences. When preservative-treated, red oak is used extensively for crossties, mine timbers, and fence posts.
