Strength and mechanical properties
The hard maple is the state tree of Wisconsin, Vermont, New York
and West Virginia. In the North, during the cold nights and warm
days of late winter, the sugar maple is tapped for its sucrose-containing
sap, the source of maple syrup. It may take up to 30 gallons of
sap to make one gallon of syrup. Early American settlers used maple
ashes to make soap and Native Americans crafted their spears from
hard maple. Until the turn of the century, the heels of women's
shoes were made from maple. Maple has been a favorite of American
furniture makers since early Colonial days. Hard maple is the standard
wood for cutting boards because it imparts no taste to food and
holds up well.
Where it Grows
Eastern U.S., principally Mid-Atlantic and Lake states. A cold weather
tree favoring a more northerly climate, its average height is 130
feet.
Main Uses
Flooring, furniture, paneling, ballroom and gymnasium floors, kitchen
cabinets, worktops, table tops, butchers blocks, toys, kitchenware
and millwork: stairs, handrails, mouldings, and doors.
Relative Abundance
4 percent of U.S. hardwoods commercially available.
Did You Know?
A single sugar maple tree produces up to 12 gallons of sap
a year.
General Description
The sapwood is creamy white with a slight reddish brown tinge and
the heartwood varies from light to dark reddish brown. The amount
of darker brown heartwood can vary significantly according to growing
region. Both sapwood and heartwood can contain pith fleck. The wood
has a close fine, uniform texture and is generally straight-grained,
but it can also occur as "curly," "fiddleback," and "birds-eye"
figure.
Working Properties
Hard maple dries slowly with high shrinkage, so it can be susceptible
to movement in performance. Pre-boring is recommended when nailing
and screwing. With care it machines well, turns well, glues satisfactorily,
and can be stained to an outstanding finish. Polishes well and is
suitable for enamel finishes and brown tones.
Physical Properties
The wood is hard and heavy with good strength properties, in particular
its high resistance to abrasion and wear. It also has good steam-bending
properties.
Availability
Widely available. The higher quality grades
of lumber are available selected for white color (sapwood) although
this can limit availability. Figured maple (birds-eye, curly, fiddleback)
is generally only available in commercial volumes as veneer.
