Rolling Punched Angle
Rolling Punched Angle
(OP)
When you roll angle iron does it bend around the centroid or does the roller cause the angle to bend around a different axis? Also is there any way to determine which point it will bend around if there are slotted holes in 10” intervals on the leg out of the roller?

There is a third possibility here; it may bent around the centroid of the narrow section inboard of the slots, after the web outboard of the slots fractures.

Mike's third possibility would depend on the size of the slot and the amount of metal left outboard of it.
If you are rolling leg out(The easy way.),that leg will mostly be stretched and you may get some reduction in metal thickness at the slots.
