Chicago Metal Rolled Products (CMRP) specializes in bending metal in all its forms—tubes, beams, bars, pipes, angles, channels, tees, sheet, and plate. We offer complete, turnkey metal bending services to meet your application and performance requirements. With over 100 years of experience and a host of metal bending capabilities, we can deliver the products you need, just the way you need them.
Our metal bending capabilities include:
Induction bending minimizes material deformation and distortion in cross-sections, even in tight radius bends. A “hot bending” process, induction bending limits wall thinning, rippling, and ovality, and consistent and reliable results. Heat induction bending can be used to bend large pipes, steel beams, and square and rectangular tubes.
Compound bending can be used to create a variety of architectural shapes, including arched roofs, domes, and canopies. An effective process for bending heavy and light gauge metal angle, tube, beam, bar, channel, sheet, and plate, our compound bending experience ensures curves and bends that are true and plumb.
Also known as “helical bending” or “spiral bending”, this process is used to produce continuously curved or coiled shapes—think of the heating element on an electric stovetop. Helical spiral bending is ideal for creating spiral staircase stringers and handrails, as well as other elegantly curved architectural pieces.
Mandrel bending is a method of bending tubing and pipe to a give centerline radius of 180° or less. Our mandrel bending process utilizes a mandrel placed inside the pipe or tube to prevent it from collapsing or ovalling as the pipe/tube is bent around a die. We can produce mandrel bends in any diameter or radius your project requires.
Our extensive metal bending experience and expertise enables us to create structural steel pieces, as well as bent plate and sheet, with tight radii and no unwanted distortion. We can produce multi-radius bends (see below), compound bends, reverse curves, and more, all with the tight radii your designs call for.
To eliminate splices and material waste, CMRP can provide multi-radius bends in a single workpiece. We can produce parabolas, ellipses, and special cambers to match your specifications. Multi-radius bending is ideal for ornamental work and structural supports, among other applications.
Sometimes known as “conical rolling,” off-axis bending is specified by citing major and minor diameters and the height and degree of arc of the required end piece. Off-axis bends are used in an array of construction applications, such as domes and roof supports.
Reverse curves, also called “S” curves, are those in which the center of the radius flips from one side of a curved part to the other. Chicago Metal Rolled Products uses a variety of metal bending techniques to produce reverse curves that match our customers’ exact specifications.
