A metallic stud of the kind used to serve as a spacer between the inner lining and the external cladding of a building unit is made from for example a galvanised and plastics-faced steel sheet 1 formed with two substantially parallel, spaced-apart flanges 11, 12 connected by a web 10. A plurality of slits 2 are formed, for example punched, in the web 10, these slits being spaced apart in the longitudinal direction of the web. The spacing apart of the flanges 11, 12 is then increased to form openings in the web, which openings are separated by spacers disposed substantially perpendicular to the flanges 11, 12. Each spacer is arranged to terminate at each end in a fold, the apex of which rests on the inner surface of the adjacent flange. IMAGE
