Not only for metal suppliers, this is daily business feeding punch presses.
Straightening and shearing from coil is relatively impressive, spend an hour in a plant when it's rolling into square or rectangular tubing. . .

I have always wondered, why, if they are going to make it into sheets anyway, why not skip the rolling and cut it into sheets at the mill?
