Maple Lumber Properties & Uses
Maple lumber is broadly classified into two groups, hard
maples (sugar maple & black maple) and soft maples (red
maple, silver maple, bigleaf maple & silver maple). Below
are descriptions and a summary of working properties from
the USDA Forest Service's Wood
Handbook. The Handbook provides much more technical
information on all commercial North American species.
Hard Maple
Hard maple includes sugar maple (Acer saccharum) and
black maple (A. nigrum). Sugar maple is also known as hard
and rock maple, and black maple as black sugar maple.
Maple lumber is manufactured principally in the Middle Atlantic
and Great Lake States, which together account for about two-thirds
of production.
The heartwood is usually light reddish brown but sometimes
considerably darker. The sapwood is commonly white with a
slight reddish-brown tinge. It is roughly 7 to 13 cm or more
(3 to 5 in. or more) wide. Hard maple has a fine, uniform
texture. It is heavy, strong, stiff, hard, and resistant to
shock and has high shrinkage. The grain of sugar maple is
generally straight, but birdseye, curly, or fiddleback grain
is often selected for furniture or novelty items.
Hard maple is used principally for lumber and veneer. A large
proportion is manufactured into flooring, furniture, cabinets,
cutting boards and blocks, pianos, billiard cues, handles,
novelties, bowling alleys, dance and gymnasium floors, spools,
and bobbins.

Soft Maple
Soft maple includes silver maple (Acer saccharinum),
red
maple (A. rubrum), boxelder (A. negundo), and
bigleaf maple (A. macrophyllum). Silver maple is also
known as white, river, water, and swamp maple; red maple as
soft, water, scarlet, white, and swamp maple; boxelder as
ash-leaved, three-leaved, and cut-leaved maple; and bigleaf
maple as Oregon maple. Soft maple is found in the eastern
United States except for bigleaf maple, which comes from the
Pacific Coast.
Heartwood and sapwood are similar in appearance to hard maple:
heartwood of soft maple is somewhat lighter in color and the
sapwood, somewhat wider. The wood of soft maple, primarily
silver and red maple, resembles that of hard maple but is
not as heavy, hard, and strong.
Soft maple is used for railroad crossties, boxes, pallets,
crates, furniture, veneer, wooden ware, and novelties.
