    h beam vsi beam steel (14 difference analysis) machinemfg

    The rolling of H-beam steel is different from that of ordinary I-beam which uses only one set of horizontal rolls. Due to its wide flange and no slope (or very small slope), a set of the vertical roll must be added for simultaneous rolling. As a result, the rolling process and equipment are more complicated than the ordinary rolling mill
