White Oak (Quercus spp.)
Description: The sapwood is light-colored and the heartwood is light to dark brown. White oak is mostly straight-grained with a medium to coarse texture, with longer rays than red oak. White oak therefore has more figure.
Main Uses: Furniture, flooring, architectural millwork, mouldings, doors, kitchen cabinets, paneling, barrel staves (tight cooperage) and caskets.
Physical Properties: A hard and heavy wood with medium bending and crushing strength, low in stiffness, but very good in steam bending. Great wear-resistance.
Availability: Readily available but not as abundant as red oak.
Working Properties: White oak machines well, nails and screws well, although pre-boring is advised. Since it reacts with iron, galvanized nails are recommended. Its adhesive properties are variable, but it stains to a good finish. Can be stained with a wide range of finish tones. The wood dries slowly.
