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.

This model W24S-100 belongs to the old model of BIT, which has now been replaced by W24S-140.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.
Many Chinese customers refer to the flat steel bending machine as a flange roll forming machine. For BIT, it is just an ordinary section bending machine for bending flat steel.
Sturdy body and strong section bending ability, BIT section bending machine can bend higher strength stainless steel bar like flat iron bar.
\In the picture, the BIT section bending machine uses the function of a tee bending machine, and it is bending a high-strength stainless steel tee.
A quicker and more effective way to straighten tees is with a BIT serise section bending machine (also called a “profile bending machine,” or an “section bender.”). The curved steel tee is run through large rollers with smaller calibrating rollers until it is straight.
