A supporting element for lattice structures comprises at least one channel shaped structural section including an endwall flanked by obliquely oriented adjoining wings. Regularly longitudinally spaced securement notches are provided for securing lattice or wire cable trays the supporting element. The notches comprise longitudinally extending cutouts in each of the wings. The cutouts are defined by longitudinal and lateral edges in the wings. Regularly spaced lands extend between successive notches. Tongues longitudinally extend from the lands and partly overlying the notches. Gaps are defined between free edges of the tongues and adjacent lands. The tongues are bendable from a position generally in alignment with associated lands to a deformed position extending into the notches for restraining a section of the components between an underface of the tongues and the edges in the wings. According to a preferred embodiment two such channels shaped structural sections are joined by a common basewall to define a one-piece omega-shaped section. An X-shaped beam is also provided comprising omega-shaped sections fixed together at their basewalls.

[ I claim:] [3.] An X-shaped beam member for supporting lattice structures including wire cable trays and comprised of wirelike or rodlike elongate components having a transverse dimension, said beam member comprising a pair of generally omega-shaped structural sections fixed back to back to each other along respective basewalls, each of said omega-shaped structural sections including a pair of channels shaped structural portions including an endwall flanked by wings, one of said wings of each of said channels being joined to the basewall of each of said omega-shaped structural sections, the channel shaped structural portions of each of said omega-shaped structural sections being arranged symmetrically relative to said basewall, each of said channel shaped portions having regularly longitudinally spaced securement notches for securing sections of components to the supporting element, said securement notches of the channel shaped structural portions of each of said omega-shaped structural section being transversely aligned with each other.
