Bar Bending

Bar Bending

Because bars are solid metal, they bend very well. Bending bars is the easiest when the sections to be bent are rounds, half rounds, squares, hexagons, or rectangular, and need to be bent “the easy way.” Bending bars the easy way (y-y axis) creates a belt-like shape; bending bars “the hard way” (x-x axis) creates what looks like a giant metal washer. All else being equal, bending bars that are flat the hard way is the most difficult bar bending process.

Minimum Bending Radius When Bending Bars

There is no mathematical formula to determine the minimum bending radius of steel sections.

To explain this better, let’s look at steel bending. The steel is bent using a cold rolling bending process.
