Flat steel products are commonly known as steel sheet/coil and steel plate. These are categorised in various types including hot rolled coil (HRC), cold rolled coil (CRC), metallic coated steel, organic coated steel, coil plate and reversing mill plate.
Most steel plate is produced in the thickness range between 5mm and 80mm. Plates are overlaps with hot rolled coil at the lower gauges. steel plates are of two kinds, reversing mill plates and coil plates. Reversing mill plates are produced by rolling slab back-and-forth and are relatively higher in thickness compared to coil plates. On the other hand, coil plates are made by rolling in tandem mills in a single direction.
Steel sheet/coil thickness is usually lower than 5mm. Steel sheet products also include hot rolled sheet, cold rolled sheet, metallic coated sheets and organic coated sheets. Hot rolling is performed at recrystallisation temperature of steel over 1700° F. At this temperature, steel is easy to deform. Following the cooling process, HRC provides less precision and relatively poor surface finish compared to cold rolled steel.
