Claim:
1. A bar for a support structure of a false ceiling, said bar being elongated in a longitudinal direction and including at least two sheet metal portions located side by side or overlapping, in contact, or adherent, with each other along said longitudinal direction, in a long-side direction, wherein, in said bar, a transverse direction, in a short-side direction, extending transverse to, or intersecting, said longitudinal direction, is defined, wherein both the sheet metal portions have cuts which are arranged, are directed, or extend, along said transverse direction, said cuts define partially cut parts wherein a single cut is common for two pairs of partially cut parts, pairs of partially cut parts of the sheet metal portions being overlapped and shifted in pairs in a thickness direction with respect to an adjacent area of the respective sheet metal portion, and wherein, of each pair of partially cut parts overlapped and shifted in the thickness direction, a part of a sheet metal portion is protruding outwards with respect to said thickness and defines a free zone in said thickness, and at least a concave or curved profile of the other partially cut part of the other of said sheet metal portions is arranged at least partially in said free zone of the thickness of the one sheet metal portion, creating an interference between the two sheet metal portions in the transverse direction, wherein said partially cut parts have along said transverse direction and, when viewed in perspective, a profile which is at least partially curvilinear or concave, and wherein each partial cut has an uncut central zone defining a central line intersecting said partial cuts.
