WHITE OAK
Quercus spp
White oak is impervious to liquids, and has been used extensively for ship
timbers, barrels and casks. White oak is the state tree of Connecticut, Illinois
and Maryland.
DISTRIBUTION
Widespread throughout the Eastern U.S. The white oak group comprises many
species, of which about eight are commercial.
GENERAL 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.
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.
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.
MAIN USES
Furniture, flooring, architectural millwork, mouldings, doors, kitchen cabinets,
paneling, barrel staves (tight cooperage), and caskets.
RELATIVE ABUNDANCE
15.1 percent of total U.S. hardwoods commercially available. |
