Reducing our hot rolled coils through our continuous pickle line and in-line tandem cold mill (PLTCM) produces cold rolled steels ranging in thickness from .012".100" and 36"72" in width. Our investment in technology allows us to meet the tight tolerances and surface finishes customers demand in fully processed cold rolled steels.

Skin-rolled metal is only reduced by up to 1 and it may be necessary to smooth the surface to prevent wrinkling. The metal increases in ductility making it ideal for stretching later. Another main benefit of cold rolling is that finish material can be bent relatively easily.
