The present invention comprises a metal brace consisting of a strip of sheet metal the side portions of which are doubled over or bent through about 180 degrees, so that the strip, or at least a nailing flange of the strip, is of double thickness sheet metal. In this way the raw edges of the strip are safely displaced from the sides of the brace. Moreover, it has been found that it is much easier to drive a nail through two superimposed thicknesses of sheet metal than to drive it through a single piece of sheet metal of double the thickness. Therefore the bracing strip according to the invention made of light gauge sheet metal may have high strength in compression, but be easier to nail, without preformed nail holes, than a conventional bracing strip. An alternative embodiment may have formed in it a plurality of access locations to use as nail holes. The portion of the strip which is of double thickness and the access locations (if present) are flattened such that they do not have an overall thickness which is substantially equal to twice the thickness of the sheet metal.
