Red Elm (Ulmus rubra)
Description: Red elm has a greyish white to light brown narrow sapwood, with heartwood that is reddish brown to dark brown in color. The grain can be straight, but is often interlocked. The wood has a coarse texture.
Main Uses: Furniture, cabinet making, flooring, millwork, paneling and caskets.
Physical Properties: Elm is moderately heavy, hard and stiff with excellent bending and shock resistance. It is difficult to split because of its interlocked grain.
Availability: Available.
Working Properties: The wood of red elm is fairly easy to work; it nails, screws and glues well, and can be sanded and stained to a good finish. It dries well with minimum degrade and little movement in performance.
