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.
Angles are often used in tank stiffeners, matching flanges, curved lintels, hand rails, lagging rings, form work and fabricated roof trusses.
Depending upon your unique project requirements, Profile Bending angle bending may be performed on a variety of materials, including carbon steel, stainless steel, aluminum, titanium, and copper.
Can also bend all types of angle as well; including aluminum, stainless and carbon steel. Carbon angle (mill produced) is classified as ASTM A36 resulting in a yield point (PSI) of 36,000 minimum.
For very tight radius bending you can utilize a draw bending process where you must be pull the material (draw the material) around a bend die matching the desired bend radius.
But for larger or sweeping radii must be utilize a roll bending process (section bending).
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.
Rolled angle bending is a cost-effective process that eliminates sharp edges, improves strength, angle rolling delivers functional and cosmetic value for many applications.
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.
This model W24S-100 belongs to the old model of BIT, which has now been replaced by W24S-140. This is because the processing capacity of the 140 profile bending machine covers the processing range of the 100 model.

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.
