For very tight radius bending you can utilize a draw bending process where you must be pull the material (draw the material) around a bend die matching the desired bend radius.
But for larger or sweeping radii must be utilize a roll bending process (section 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.

Bar bending machine ( Bar rolling machine) can also be called the flange bending machine. The sturdy body of the BIT series profile bending machine has a strong section bending capacity and provides reliable bending services.
Many Chinese customers refer to the flat steel bending machine as a flange roll forming machine. For BIT, it is just an ordinary section bending machine for bending flat steel.
Sturdy body and strong section bending ability, BIT section bending machine can bend higher strength stainless steel bar like flat iron bar.
In the past 30 years, due to the rapid development of China’s economy, about 20% of the machines we produce are used for flange forming, especially large flange forming that is difficult to mass produce.
For example, W24S-400, the factory manager once released a video to promote its large flange, the excitement can be felt across the screen.
