This steel fabrication course of progressively bends a steady strip of steel (usually metal, stainless-steel, aluminum, or different ductile supplies) at room temperature right into a desired cross-sectional profile. The strip is fed by means of a sequence of rollers, every performing an incremental bend till the ultimate form is achieved. This course of can create advanced shapes with excessive precision and repeatability, akin to structural framing members, roofing panels, automotive elements, and customized profiles.
In comparison with scorching rolling, this room-temperature fabrication methodology affords a number of benefits, together with improved floor end, enhanced materials power attributable to work hardening, tight tolerances, and excessive manufacturing charges. Traditionally, less complicated variations of this expertise existed for hundreds of years, however vital developments within the twentieth century, together with the event of refined tooling and automation, remodeled it right into a extremely environment friendly and versatile manufacturing course of essential for varied industries.
