Particular attention should be paid to the angle bending of unequal leg angles. You must specify short leg in, short leg out, long leg in, long leg out. Otherwise the radius or diameter of such rolled angles is usually specified as measured just as the corresponding equal leg angles.

Cold bending is done on machines commonly called profile bending machine (also called angle roller or section benders) .
These machines might have three or four rolls that induce the curvature of the steel sections as they pass through the tooling.
Unequal angle bending machine ( angle flange bending machine) and angle rolling machine are two names of the same machine Unequal angles are often used in tank stiffeners, matching flanges, curved lintels, hand rails, lagging rings, form work and fabricated roof trusses.
Angle bending machine (also called angle roller) is actually just a function of section bending of profile bending machine.
Angle bending machine can roll the Equal Angle or Unequal Angle, and the angle steel after processing still keeps the two sides of the angle steel perpendicular to 90° without flanging. And there are no wrinkles.
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.
