A pole reinforcement truss has an open cross-sectional configuration characterized by opposite side flanges that diverge with respect to one another as they extend from respective opposite side edges of the truss body. In one embodiment, the cross-sectional configuration has an intermediate curved bend through an excluded bend angle and a pair of curved bridge bends on opposite sides of the intermediate curved bend each through an included bend angle, wherein all three curved bends have the same radius of curvature. The truss maintains its geometry in an improved manner after the onset of yielding, thereby increasing ultimate strength of the pole-truss assembly.
