American Hard ( Rock ) Maple

Blonde Timber Species

Species Name: American Hard Maple

Botanical name(s): Acer saccharum, A. nigrum

Size and location information: Eastern USA, principally Mid-Atlantic and Lake States. A cold weather tree favouring a more Northerly climate.

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 texture and is generally straight grained, but it can also occur as ‘curly’, ‘fiddleback’, and ‘birds-eye’ figure.

Density: Dry: 705kg/m3

Janka Hardness Rating: Dry: 6.4

Durability: Rated as slightly or non-resistant to heartwood decay. Sapwood is liable to attack by furniture beetle. The heartwood is resistant to preservative treatment but the sapwood is permeable.

Hard maple dries slowly with a large 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 and polished to an outstanding finish. 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.

Flooring, furniture, panelling, kitchen cabinets, worktops and table tops, interior joinery: stairs, handrails, mouldings, and doors.

USA: Regionally available.
Export: Widely available in a full range of specifications and grades as both lumber and veneer.
