  • Patent number: 4498323
    Abstract: In an eleven-step butterfly rolling process for producing inertial sheet piling, the upset grooving hitherto used in the fourth step is eliminated and replaced by one or more flat rolling steps intended to work the bulges at the edges of the flanges so as to impart a grain structure parallel to the flat rolled surfaces and thereby avoid cracking after the edge portion has been bent into hook configuration.
