Section bending machine can bend all types of beam / wide flange including aluminum, stainless and carbon steel.
I-Beam and wide flange are specified in similar fashions.
The most common bending method is a roll bend or pyramid bends method. Straight material is inserted into the rolls; the rolls are then moved horizontally to put the desired radius into the material. The material can also be bent incrementally hot or incrementally cold. This is where small sections of material are bent at one time. When finished the section has a smooth curve to the bent section.
