Moreover, bending imparts much strength to the sheet metal compared to their flatter counterparts.įor example, an aluminium sheet bent into a V cross section will be much stiffer and stronger than the same flat sheet.īending a metal sheet usually comes with a set of calculations and design requirements. In sheet metal fabrication, curving sheets according to a specific bend radius is one of the most common operations used to create flanges, curls, seams etc.
