Multi‑flexible rolling mills produce bars, wire rod, rebars, and light sections on a single line. A sequence of housingless stands applies controlled reductions and shape changes to the rolled product while maintaining tight thickness and profile tolerances. The housingless stands provide structural stiffness, reducing deflection under rolling forces. The overall production can include flats, squares, hexagons, and light sections to complete the rounds and rebar production, produced at rates of over 200 t/h with over 250 products rolled into a single rolling mill. The rolling mills are characterized by lower overall investment costs compared to a solution with one (or two) high-speed finishing blocks and the associated additional electrics, piping, and civil works.
