Abstract


The roll forming process shapes sheet metal using cylindrical rollers to create specific profiles. It's known for high production speed and volume. Demand for strong yet lightweight profiles has risen, but the supply chain for high-strength coil sheet material is a challenge. To meet this demand, this study explores creating profiles from coiled sheet material with improved mechanical properties through cold rolling. The cold rolling process enhances material properties, enabling the use of specialized materials in roll forming. S355MC sheet material was used, and its thickness reduced by 0.1mm through cold rolling. By analyzing the mechanical properties before and after cold rolling, we designed a rectangular profile using FEA software. This resulted in increased yield values along the profile, from 370MPa to 520MPa, achieving the desired mechanical properties.
