A light-gauge truss framing element constitutes a longitudinal constructional beam having a uniform generally T-shaped cross-section, in which a vertical portion of the cross-section defines a web of the beam and a transverse horizontal portion defines a symmetric flange. The beam comprises a material having a thickness in a range of about ten to about twenty-two gauge and having a yield strength in a range of about thirty-six to about fifty-five kips per square inch. The web, in transverse cross-section, resembles a compressed V-shaped element which may be selectably reinforced through the use of rods or stiffening elements internal or external to the apex of the V-shaped web.
