This standard applies to bent components made from flat steel products for application in steel construction and general mechanical engineering. When bending flat rolled steel, such as sheets and plates, strips, wide flats etc., the rolling in direction should be considered, since bending should if possible be carried out transverse to the rolling direction owing to the greater suitability to bending offered. The bending suitability of the rolled steel shall be agreed with the manufacturer's works when ordering.
