ABSTRACT:
A section element for constructing frames, supporting structures and the like made up of a section body (10) having one or more flat surfaces (11) and one or more rounded sectors (12) as parts of a circumference with a preset diameter. In correspondence with each flat surface (11) a longitudinal groove (13) is provided with parallel borders defining undercuts (15). The section body can be connected to other elements by means of clamps (16) each one delimiting at least one cylindrical in diameter housing matching that of the cylindrical surface defined by the rounded sectors of the section body and having at least one additional centering member designed to fit in the groove along at least one of the flat surfaces.
