Steel production. Rolling press at a steel mill. Here a press is being used to shape part of a rail for use in railway construction. The section rolling shop consists of many such presses, each making a small change to turn steel rods to form section bars - for example, I-section girders for construction and rails for railways. Photographed at the Cherepovets steel mill, Russia.
