There are two kinds of the flat bars, one is the True mill flat bar another is Sheared flat bar,The difference between a true mill flat bar and sheared or flat bar cut from the plate is dimensional tolerance. In the true flat bar, tolerances for width and thickness are restrictive and have the better finish. In cutting bar from the plate, the diametrical tolerance will be more generous and in line with the cutting method.
