Distribution:
Eastern USA and South Eastern Canada. General Description: Varies in
colour from pale yellow-brown to biscuit with a pinkish tint, similar to
European Oak. Straight grain, with the characteristic silver grain on
quartered material. Appalachian Oak is slow grown producing light weight,
mild wood, but Southern States produce fast grown Oak with wide growth
rings, and a harder, tougher timber. Medium to coarse texture. Weight
averages 760 kg/m3 (47lb/ft3); specific gravity 0.76.
Mechanical Properties: The wood has medium bending and crushing
strengths with low stiffness which makes it an excellent steam bending
material.
Working Properties: Vary according to rate of growth. Slow grown
oak being much easier to work with hand and machine tools. The timber
takes nails and screws well, although pre-boring is advised; its gluing
properties are variable; stains and polishes to a good finish.
Durability: Logs are liable to severe insect attack. The heartwood
is durable and extremely resistant to preservative treatment, and the
sapwood is moderately resistant.
Uses: Milder than European Oak to work and suitable for furniture
and cabinet making, joinery, heavy construction, parquet and strip
flooring, pews and pulpits, boat building, ladder rungs, agricultural
implements, wagon bottoms, cooperage and coffins. Has now become one of
the most popular timbers for use in shop fitting and high class joinery.
