COLDROLLED STEEL. As you might suspect, the manufacturing process behind coldrolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hotrolled steel, coldrolled steel has a nearly 20% increase in strength through the use of strain hardening.
Flatrolled steel refers to a type of processed metal that is generated via melting and stretching under an applied force. This force is used to create metal pieces in the form of sheets, strip or tin plates. These steels have flat surfaces allowing for easy treatment with zinc to help prevent corrosion of the substrate.

A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also describe plants where steel semifinished casting products (blooms, ingots, slabs, billets) are made, from molten pig iron or from scrap.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
ASTM Structural Steel (SS) Grade 80 described in Specification A1008 is often processed identically to Cold Rolled Full Hard Sheet product. Thus, the term full hard is often used to describe this product. In effect, the product attributes of Grade 80 and Cold Rolled Full Hard sheet are similar.
