Single finished cold sections are produced by hot rolling, extrusion or drawing. The multi-section elements (12) comprise at least two finished sections, (angle irons, Z-sections, T-sections, flats etc.), positioned side by side and connected lengthwise along the terminal part of an edge, separated by a web. After splitting the web from the sections (20) the edges of the sections are regauged (29), then straightened and made linear (16) at the same time. |
