Plant Uses

American elm is classed as moderate in heaviness, hardness, and stiffness. It has good shock resistance, but is moderately weak. Like all other commercial species of elm, it has excellent bending qualities. The wood is slightly below average in woodworking properties, but is among the best in ease of gluing. It is intermediate in nail-holding ability. It's used in the manufacture of containers, furniture, and dairy and poultry supplies. Because it bends so readily, it is much used for slack cooperage and kegs. Its veneer goes into fruit and vegetable boxes, crates, and baskets. It is used for crating of heavy articles, and in furniture for the bent parts of chairs and other items.
