The paper deals with a manufacturing technology of hot-rolled sections. A calibration system proposal of the solved section is described and its accuracy is subsequently verified by numerical simulation using Simufact Forming software. In this case, S355J2 steel is used as a material for a trial production of the rolled profile. Finally, according to the verified design, the trial rolling of the section is carried out. Therefore, a comparison between actual rolled section shapes of individual rolling passes and simulation results is performed. This makes it possible to assess the accuracy of the simulation and thus the suitability for use in the development of other rolled sections.
