Angle Iron, also known as L-bracket or angle Iron, is a 90° metal bracket that is often used in roof trusses. On support beams and structural platforms, Angle steels can also provide reliable stability and corrosion resistance.

Rolling Angle Iron

Angle Iron bending is a cost-effective approach to creating items with a variety of shapes that may be utilized in a variety of operations. Angle Iron sizes vary but they ensure ease of use and are a quick approach to creating new items. Angle iorn rolling, its relevance, and the methods required for the process are all discussed here.

What is the Definition of Angle Iron Rolling?

Angle Iron rolling is a process that includes applying forces to an Angle Iron to modify its shape. This is done to obtain the desired form or shape for a manufacturing process. Only the bar’s outward features are affected by the external force. The angle steel’s dimensions, such as length and thickness, remain unchanged. The angle iron’s malleability also allows it to be shaped in a variety of ways.

Methods of curved angle iron

Angle ironrolling procedures are similar in that they all have the same end aim of transforming angle iron constructions into the correct shapes. They do, however, operate differently. Knowing how to bend an angle iron requires an understanding of how the methods are determined by elements such as the thickness of the material, the size of the bend, the angle steel bend radius, and the intended purpose.

Roll Bending Angle Iron

The process of bending angle iron into rolls or curved shapes is known as roll bending.

To make different curves or a large round bend, the method uses a hydraulic angle rolling machine. Because it takes advantage of the spacing between its rollers to generate bends and curves.

Rolled angle bending is a cost-effective process that eliminates sharp edges, improves strength, angle rolling delivers functional and cosmetic value for many applications.

A common work of section bending machine (angle rolling machine) is make the angle ring or angle flange.

Angle ring also called angle flanges, commonly made of carbon steel, stainless steel or aluminum, an angle ring is made by rolling a piece of structural angle into a ring and then welding the ends together. Typically, the ring is rolled with the horizontal leg radiating out from the center to create what is called a “leg-out angle ring” (as opposed to a “leg-in angle ring” or “off-axis” angle ring.)

What are angle rings used for?

Angle rings are components in air systems where movement of air or movement of material by air is done. They are used in pollution control systems, agricultural equipment such as grain handling and a multitude of other applications.

How to bending angle?

Leg-out rolled angle rings resemble an old-time straw hat (minus the top) where the leg out would be the brim. Heel-in rolled angle rings look like, and can function as, pulleys. The most difficult orientation in curved angle iron is leg in. When not done correctly, there will be distortion in the horizontal leg (the leg in) that looks like an off-set. With the proper methods and tooling, this distortion will be avoided.

Rolled Angle Flanges & Angle Roller

Angle rolled leg in should be specified by the O.D. of the ring for most cases since there are two I.D.’s of the ring; the I.D. of the easy way leg and the I.D. of the hard way leg. Heel out custom rolled angle should be specified by the outside diameter.Heel in angle should be specified by the inside diameter.

What can BIT angle iron roller do?

BIT section bending machine’s Bending angle bending may be performed on a variety of materials, including carbon steel, stainless steel, aluminum, titanium, and copper to make curves, angle iron rings, angle iron flanges, angle iron pipe supports, and many other parts.

Our section bending machine have the capabilities to bend angles in nine orientations, a claim not every company’s profile bending machines can do it. PBH angle rolling machines can produce leg in, leg out, short leg in, short leg out, long leg in, long leg out, heel in, heel out, and heel up angles to meet your specifications.

Hydraulic angle roll benders can bending rolled angle rings that are bent off-axis, with multiple radii, helically, or into compound bends


BIT angle roller’s angle bending applications include but are not limited to:

  • Angle flanges
  • Tank supports
  • Ladle lips
  • Fan housings
  • Tank supports
  • Roof supports & roof systems
  • Architectural accents
  • Flanges
  • Steering mechanisms
  • Ladle lips
  • In structural applications, angles are often used back-to-back to support roofs.
  • Angle steel segments are used in steering mechanisms for farm equipment.

Angle Iron Bending Glossary

  • Angle bending – A metal forming process used to form angle iron to a specific degree or angle.
    Generally angle iron bending differs from angle iron rolling in that it is more concerned with forming the angle iron to a specific angle or degree, rather than a curve or radius.
    Angle iron bending can sometimes be used as another word for angle iron rolling. Both refer to the metal forming processes in which angle irons are formed to a specific degree, radius or curve.
  • Angle rolling – A metal forming process used to form angle iron into curves and or radiuses.
  • Angle rolling leg-in – A metal forming process used to form angle iron into curves and or radiuses.
  • Angle rolling legs-out – A metal forming process used to form angle iron into curves and or radiuses.
