Century Dictionary and Cyclopedia

1. n. A rolled or wrought bar of iron in the form of angle, used in iron constructions. Angle-irons are made with sections in the form of right angles, with equal or unequal sides; in the shape of double angles, when they are called channel-irons; and in the form of the letters T, I, and Z, from which they take the names of T-, I-, and Z-irons. They are used for joining piece to piece in every kind of ironwork, as well as for forming component parts and principal members (as the ribs of ships, the V-girders of bridges and floors) in all iron structures. Also called angle-bar.
