A spacer bar (14) of thin sheet metal adapted to be mounted on a building wall structure (10) to support a wall cladding comprises a generally flat web (16), an outer flange (17) for attachment of cladding support members (15) to the spacer bar (14), the outer flange extending along one of the longitudinal borders of the web and projecting from the web substantially perpendicularly to the plane of the web, and stiffening elements (20, 21) which extend transversely of the spacer bar (14) and are spaced apart along the length of the spacer bar, the stiffening elements being formed by portions cut out of the web and bent to include an angle with the plane of the web. The web (16) is provided with slits extending transversely of the spacer bar (14) across the major portion of the width of the web, and the web portions adjoining the slit on both sides thereof are bent out of the plane of the web to form the stiffening elements (20, 21). |
