Elm trees have a long-standing reputation in the furniture industry due to their strength and unique grain patterns. However, some may question whether elm is a hardwood or not and if it is a practical option for furniture construction.
Thus, our wood specialist explored these questions further to assist you in deciding whether Elm wood furniture is the right material for your project.
Differentiating Softwoods and Hardwoods
Deciduous trees are classified as hardwoods. These hardwood or deciduous trees are characterized by their ability to flower and shed their leaves during winter and autumn.
Additionally, deciduous trees belong to the angiosperm group, which has a unique cellular makeup that affects water distribution.
Softwood trees, on the other hand, are evergreen trees that have needles and produce cones instead of flowers, which are usually wind-pollinated. Softwood trees also belong to the gymnosperm group, which affects their cellular makeup and water transport mechanism.
One way to differentiate between hardwood trees and softwood trees is by examining their seeds. Hardwood trees produce seeds that are encased in a shell, while softwood trees produce unenclosed seeds that simply fall to the ground.
Soft Hardwood vs Hard Hardwood
After identifying whether the lumber is hardwood or softwood, you can classify it further based on its nature into either hard hardwoods or soft hardwoods.
Balsa wood is one example of those soft hardwoods derived from a hardwood tree that is easy to carve and is relatively softer compared to hickory, another species of hardwood tree. As a result, balsa wood is considered a soft hardwood tree, whereas hickory is a hard hardwood tree.
About Elm Trees and Wood
An Elm tree is a hardwood tree that shed its leaves during winter and fall but grows new ones during spring.
This kind of hardwood tree grows fast and can reach up to one hundred forty feet tall but usually grow between sixty and one hundred fifteen feet tall with a trunk diameter of three to six feet.
However, these days full-grown elm trees, especially American Elm, are now limited due to the Dutch elm disease, also known as DED.
There are more than 30 types of elm trees, offering a broad range of wood choices. However, among the family of elm trees, the most famous types are the English elm trees, red elm trees, and American elm trees.
In addition, elm wood exhibits a striking contrast in color between its sapwood and heartwood, with the heartwood showcasing shades of light to medium reddish-brown and the sapwood displaying a much lighter or off-white hue.
Moreover, unlike other woods, elm wood grain is distinct and remarkable, characterized by interlocking patterns and a rough, uneven texture with swirling and wavy growth rings that give it an extraordinary appearance.
Is Chinese Elm a Soft Or Hard Wood?
Chinese Elm tree is sometimes difficult to categorize as it is commonly known as a “soft hardwood tree.” This is due to the fact that while it is sturdy and long-lasting enough to be categorized as a hardwood tree, it is still not as hard as most other hardwoods.
Characteristics of Elm Wood
Elm wood displays a shade of light to medium brown with an interlocked grain pattern and an uneven, coarse texture. This makes it highly resistant to splitting, making it a valuable and durable type of soft hardwoods.
However, as a soft hardwood, it’s less dense and softer compared to other hardwood trees. Thus, this characteristic makes it susceptible to environmental factors and insect infestations, which eventually lead to its low durability.
Despite its unique interlocking grain pattern, it is challenging to handle due to its low workability. When working with this deciduous tree, we recommend utilizing power tools instead of hand tools to avoid damage or tear out.
Nonetheless, to help you get to know more about this type of deciduous tree, below is the list of its remarkable characteristics:
- Wood Species - Elm Wood
- Hue - Light to medium brown
- Density - 500 kilogram / m3
- Hardness - 830 pounds-force (lbf) or 3692 newtons (N)
- Stiffness - 1.34 million pounds per square inch (Mpsi)
- Type of Wood - Soft hardwoods
- Common Uses - Sticks for hockey, Boxes, Furniture
Janka Rating of Elm Wood
Elmwood is considered one of those many types of soft hardwood, which sets it apart from the hardness of most hardwoods.
Nevertheless, it is harder than all types of softwood. Thus, Elm trees are more dense than any other softwood because their density is higher.
