ABSTRACT:
This specification discloses a method of and apparatus for forming concrete reinforcing elements having enlarged ends and also discloses a reinforced composite incorporating such elements. In one embodiment the enlarged ends are formed by folding the edges of a strip of sheet metal onto itself while in another form the enlarged ends are formed by edge rolling a strip. In both cases the reinforcing element is formed by transversely shearing the strip after its edge has been modified. The reinforcing elements as described above are shown to have a greater pull-out resistance than plain elements.
