Flat bars are flat, rectangular-shaped bars that are used for many applications from structural to architectural. Most carbon and alloy steel flat bars, commonly referred to as “strip”, under ¼” thick are processed from coil stock and straightened while, typically, ¼” and over are hot rolled at the mill. Stainless steel flat bars ½” thick and below are usually slit from the coil and edge conditioned through a Gauer process. Although stainless true bars can be produced below ½” in thickness, the majority of stainless true bars are ½” and above and hot rolled and/or cold rolled at the mill. Aluminum flat bars are extruded.
