An integral, one-piece, metallic chord for use as the top and bottom chords of a roof truss. The chord comprises an elongated member of generally U-shaped, singly symmetric cross-section, having a base terminating at its longitudinal edges in mirror image legs. The base portion is planar with a central depressed rib formed therein and extending the length thereof. Each leg comprises a first planar portion perpendicular to and extending from its respective longitudinal edge of the base, followed by an inwardly sloped planar portion leading to a planar attachment portion which is perpendicular to the base portion and which terminates in a flange portion extending outwardly of the attachment portion and then upwardly and inwardly, ending in a longitudinal edge facing the attachment portion. The flange portions form semi-closed reinforcement members. The legs and their flange portions constitute the sides of the chord. The first planar portion of each leg and the outermost part of the flange portion of each leg are co-planar, so that the chord will lie flat on either of its sides.
