Against common cold rolled RHS or MSH-sections, the sharp-edged RHS from Montanstahl consist of four flat bars that are welded together with four welding seams to the needed geometry and size. Each thickness of the flats can be defined individually and permits an ideal static design for the section with maximal weight savings.
