Not every steelmaking method necessitates heating steel to its recrystallization temperature or above. Cold rolling, for instance, is conducted at ambient temperature. Predictably, it demands higher pressure for shaping and rolling steel at room temperature. Despite this, cold-rolled steel, manipulated well below steel's recrystallization temperature, offers numerous advantages. Here are some of the primary benefits of cold-rolled steel.

After the introduction of color coated steel in the United States in 1936, it was first applied to movable shutters, rain barriers and so on. The production process has been improved from the initial one coating and one baking to two coating and two baking or three coating and three baking, and the color coated steel sheets are widely used in construction, automobile, container, instrument shells, etc.
