Angle Rolls are very common machines in environments where metal profiles need to be formed to a specific radius or diameter. Angle iron, solid square, solid rectangle, round tubing, and pipe are the most common type of profiles used with this type of equipment.
Angle roller (also called Angle Roll, Angle Iron Roller, Angle Roll Machine, Section Bending Machine, Aluminum Bending Machine) is just a function of section bending of PBH profile bending machine.
What is an Angle Roller?
Angle rollers (angle rolls) are machines that rolled bend metal (such as iron, stainless steel, aluminum, copper, etc.) profile coils into arcs that are useful for specific purposes.
The angle roller(angle roll) has a common name: profile bending machine. It can bend tubes, pipes, round & solid square & flat bars, angles, tee sections, H & I beams, and U channels to over 180 degrees and into circles or arcs, and is often chosen to create circular pieces.
3 DIFF types of angle roller
Angle rolls are divided into three forms according to the different roll bending processes: pyramidal angle rolls, single pinch rollers, and double-pinch profile bending machines.

Angle Roller 101: Your Complete Guide To Angle Roll Machine
Name Definition
Angle iron roller, also known as angle roller, angle roll, angle roll machine, profile bending machine, angle ring roller, section bending machine, ring roller machine, or simply “rollers,” are all names used for the angle iron bender machines metal fabricators use to make round bends in metal profiles.
Rollers are the round parts that spin to bend and shape the metal within the machine. Each has at least one pinching roll that’s used to feed the metal into the machine.
Angle rolling machines come in single-pinch, double-pinch varieties. Double-pinch rollers offer more precision and can handle longer sheets of metal. The following figure provides the photos of the two angle roll models.
Three types of angle rolls
The number of rolls an angle roll has is another important difference.
Another difference between angle iron rollers is the number of rolls it has. The rolls are the round, spinning parts of the angle roll that allow it to do its job.
Every angle iron roller comes with at least one pinching roll, which is the roll that holds the metal in place and allows it to be fed through the angle bender machine.
Angle iron rollers come in one or two varieties: single-pinch and double-pinch, referring to how many pinching rolls it has.
Double pinch angle roll machine
In the double pinch angle roll machine, the top roll has a fixed position, while the bottom two can move and can be moved independently one from the other. This kind of machine is the most flexible, and consequently is the one that allows for obtaining better performances The possibility to move independently the bottom rolls allow to manage in the best way the pinching and bending operations, permitting them to work symmetrically and asymmetrically.
Pyramidal of angle iron roller
In the pyramidal section bending machines the bottom rolls have fixed positions, while the top one can be moved down. With this kind of angle iron roller, it is possible to work only in a symmetrical way.
Single pinch angle rolling machines
In the single pinch angle rollers, only one of the bottom rolls can move. With this, kind of angle iron roller it is possible to work only in an asymmetrical way.
We can’t even find its pictures on the Internet.
Difference of three angle rolls
Production costs
The double pinch angle roller style is the most expensive one to be constructed because there are more movable parts and consequently more components.
The pyramidal angle iron roller and single pinch profile bending machine have more or less the same production cost.
Flexibility
Double-pinch angle rollers are the most flexible.
During operations, it is possible to maintain A stable position of the profile at the loading side of the Angle Roller and use only the roll at the opposite side to bend the steel or aluminum profile.
It is possible to operate in this way also in the single pinch style section bending machines, but not on the pyramidal section benders.
How Do Angle Iron Roller Work?
The basics of an angle roll machine operation are fairly simple. The process consists of taking the flat edge of the part, feeding it into the angle iron roller, and using the pinching action of two of the rollers the third roller is brought up to begin the bending process. These 3 rollers are then driven simultaneously forward and backward bending the metal to the shape desired in a series of “passes”. Depending on the yield strength of the material and the desired final shape the number of “passes” will vary. The benefit of using this method to form parts is that there is a smooth radius created and a smooth transition of radius’s from parts with varying radii.
Metals Used in Angle Rollers
Angle roll machines (angle iron roller) can form a variety of materials such as steel, titanium, aluminum, stainless steel, and most other malleable metals. These metals can be tubes, pipes, flats, angles, solids, extrusions, or just about any other profile you can imagine.
Different Roll mold Styles
BIT angle rolls can be equipped with a variety of tooling roll mold sets. Standard with every angle iron bender machine is a universal set of rolls mold that allows for a variety of shapes and profiles to be formed.
Round pipe bending needs to customize the mold according to the diameter of the pipe.
3-roll angle roller & 4-roll angle iron roller
Pressing rolls are the part of the angle roll bender that does the actual bending. Here there are even more varieties than with pinching roll.
Examples of different types of angle rollers based on the number of pressing rolls include three-roll double-pinch, four roll double-pinch, three-roll initial pinch, and more.
5 TIPS FOR CHOOSING THE BEST ANGLE IRON ROLLER
Choosing an Angle Roll Machine may seem difficult but it really breaks down into a few simple steps. First, determine the maximum size and type of material you will be rolling. Next determine the types of profiles (angles, flats, tubes, etc.) that you will be forming. Lastly determine if you will be rolling material into one simple radius or if you will have or need the ability to have, the capability of forming variable radii.
Pressing rolls for angle roller
Pressing rolls are responsible for the bending process and come in far more varieties than angle iron rollers. Common examples include four-roll double-pinch and three-roll initial pinch.
Angle iron roller is actually just a function of angle iron rolling of profile bending machine. Our angle roller is named as an angle iron bending rolling machine, angle roll, and angle iron roller.
Angle rolling machine (Angle Iron Roller) can roll the Equal Angle or Unequal Angle, and the angle iron or angle aluminum after processing still keeps the two sides of the angle steel perpendicular to 90° without flanging. And there are no wrinkles.
Yield strength
Regarding the yield strength of the angle iron roller, BIT machines are uniformly calculated based on the yield value of Q245 and have a yield strength of between 36,000 and 38,000 pounds per square inch (PSI).
If you have special requirements, please indicate the yield strength of the metal material in the inquiry.
The yield value of Q245: refers to the yield value of this material, around 245MPa (34,075 psi).
Correctly sized
Whether operators are bending angle iron, tool choice is critical. The tools need to fit the profile yet not be so tight as to negatively affect workpiece shrinkage and growth. A tool that’s too tight can cause localized distortion and, at worst, actually gouge the material surface.
When operators need to bend an open profile like an angle, they have fewer distortion-mitigating tools at their disposal. Beyond tool choice and fit-up, angle iron roller must choose a correctly sized machine, one with sufficient forming tonnage and adequate grip lengths—enough to provide the needed leverage to reduce distortion, but not so long that they will require an excessively long sacrificial straight section, the long sacrificial flat section becomes expensive scrap, reducing the roll shop’s competitiveness.
HOW DO MINIMIZE THE UNBENT FLAT OF THE ROLLING ANGLE PROCESS?
BIT’s angle iron roller has the independent motion of the two side rolls allowing the operator to minimize the sacrificial unbent flat sections on the workpiece.
Again, typically a roll shop that bends a small workpiece on a large section bending machine (angle roller) must factor in a long flat section, which increases material costs.
But because the BIT angle rollers (profile bending machines) move the way they do, an operator can move a joystick or push a few buttons on the control to reconfigure them into a smaller-machine orientation. Beyond this, operators can fine-tune the roll position to minimize the unbent flat even further.
Different bending capacities of angle rollers
The types of metal an angle iron roller can process largely depend on its bending capacity, we use the section modulus to evaluate the capabilities of the angle iron roller.
Capacity is one of the most notable differences between these angle iron rollers, each angle roll has a section modulus rating.
Make a list of the materials and the size of the metal profile you work with on a regular basis and consult an expert to figure out what type of angle iron roller is best for you.
When determining which angle rolling machine is best suited for the task one has at hand, it is important to research what each section bending machine is designed to do, and to understand the materials that one will be working with.
We provided detailed information about the section bending machines, such as capacity and yield.
