Chicago Metal are the bar bending experts. We have extensive experience in bending bars of all sizes and shapes—round, half-round, square, hexagons, and rectangular (also called flats)—into rings and ring segments.
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.
It is often more economical to bend bars into rings or ring segments instead of burning these shapes out of plate, as bar rolling can provide a greater yield of usable material with less scrap (and, therefore, lower material costs).
With our bar bending experience and expertise—along with proper tooling, methods, and machinery—we can bend relatively thin and wide bars to tight radii with little to no distortion. We can bend a wide variety of bars, including hot rolled, stainless, aluminum, Inconel, brass, copper, and other alloys. We even bend rebar.

To add further value to our bar rolling services and give you more complete products, we offer a range of secondary services. We can weld, punch, bevel, grind, drill, and machine your bars, as needed.
Applications for bar bending include creating rolled rings (with beveling, welding, and grinding) to use as flanges on rail car discharge chutes, component parts for trucks, tractors, tanks, fan housings, wind towers, and wastewater treatment equipment. We have cambered heavy bars for axles on Caterpillar tractors. We have curved 4140 forged bars into rings and ring segments as gear blanks.
