Cold Drawn Steel Profiles - Cold Rolled Steel Profiles

Cold drawn profiles are produced by pulling metal bars or coils through dies at ambient room temperature. This causes plastic deformation, cold working, of the metal as it forms to the profile configuration cut into the die. Depending on the profile configuration being made, multiple pulls through dies may be required with an anneal in between each pull . Benefits of cold drawn profiles include improved mechanical properties, consistent dimension along the length of the profile with less tolerance variation as compared to hot extrusion and hot rolling, and a much improved surface finish superior as compared to hot extrusion and hot rolling. Cold rolled profiles are produced by passing metal bars or coils through a set of rolls at ambient room temperature. This causes plastic deformation, cold working, of the metal as it forms to the profile configuration cut into the rolls. Depending on the profile configuration being made, multiple passes through the rolls may be required with either no anneal between each roll pass or with an anneal between roll passes. Benefits of cold rolling include the ability achieve a greater amount of cold work as compared to cold drawing. This translates into reduced costs as compared to cold drawing. Cold rolled surface finishes are better than that achieved via cold drawing. However, cold rolled dimensional tolerances can not be controlled to the same degree as cold drawing.
