CRS on a plan denotes Cold Rolled Steel. Cold rolled steel is steel that has been processed at room temperature to produce a smoother surface, tighter tolerances, and often higher yield strength than hot‑rolled steel. This makes it the standard shorthand you’d see on drawings when the specification calls for cold rolled material. The other terms aren’t standard plan abbreviations for the material itself, and “cold rolled sheet” specifies a form rather than the material type, so the intended material designation is cold rolled steel.
