Flat Steel Bar
Action Stainless stocks sheared and edge conditioned flat bar in grades 304, and 316. Other alloys are available upon request. Extruded bars are also available upon request in a wide range of grades, sizes and alloys.
Flat bar is produced in a variety of different processes:
Extruded Flat Bar is drawn through a preformed die. To draw, is to “pull through or into”. The edges of drawn flats and square bars are closer to a true 90 degree angle and are sometimes referred to as “ true bar”. Production in this manner allows for tighter tolerances to be maintained. These bars are standard mill products of 10ft to 12ft random lengths and come in a wide variety of grades, sizes and alloys.
Sheared Flat Bar, not too long ago, was referred to as "sheared and gauered bar". In 1946 Walter Gauer invented a process for removing the razor sharp edges that the shearing process created. Today the more common term used for the process is "edge conditioned". Below is a standard tolerance chart for sheared and edge conditioned material.
