Hackberry - wood, parquet, profileThe deciduous tree Hackberry belongs to the Elm family and is quite widespread in the east of the USA. His Latin name is "Celtis occidentalis" and he is closely related to the Sugarberry.
As a parquet Hackberry is known in our latitudes as "North American Hackle Tree".
In the US, hackberry is sufficiently available as lumber, but mostly in thin standard thicknesses and less good quality grades. The wood is only slightly exported, because due to its negative characteristics, demand in the world is low.
Properties and uses of Hackberry
In the US, it is also less used as timber, but rather as firewood. This is primarily due to the fact that hackberry has large shrinkage and is very susceptible to deformation during processing.
In addition, it is prone to blueing before and after the technical drying. Even though the wood is very heavy, it can be planed and turned very well, nails and screws hold only medium good. Furthermore, the wood has an irregular grain, which is sometimes straight, sometimes oblique and sometimes provided with a fine and uniform structure.
In addition, hackberry is not particularly resistant to heartwood rot and it is prone to infestation by insects. While the heartwood can absorb only moderately, the sapwood is well receptive. For all these reasons
it is not a preferred wood for
the furniture industry.
When furniture is made from hackberry, it is kitchen cabinets, showcases, or it is used for doors and laths as well as various carpentry work. However, Hackberry can be treated well with thermo wood so that it can be used outdoors.
Due to the thermal treatment, the durability class 1 to 2 can be achieved. The construction of wooden terraces is very popular with this wood, especially because it gets a pleasant dark brown color after treatment and thermo wood. In addition to decking, fences are also made for the exterior of Hackberry.
A positive feature of Hackberry is that it is very flexible. Therefore stalks or sports equipment are often made from hackberry.
Hackberry as a tree
Nevertheless, the Hackberry is said to have a high resistance, so it is often planted as a street tree. The tree grows very straight and can grow up to 20 meters high. In the outdoors, it often occurs at altitudes up to 1500 meters.
Its leaves are ovate and sawn and alternate on branches. When the leaves have fallen off, the orange to purple drupes will stay on the branch for some time longer. There is only a small difference between the core and the sapwood, because they are yellowish gray to light brown and have yellow stripes.
