Hot-rolled steel coils are produced by hot-rolling in hot strip mills, which can be semi-continuous, continuous, reversing or non-reversing. Coils can also be made through compact strip production . After hot-rolling, coils have a wide range of applications: they are used to make profiles and shapes for construction and machine-building, as well as general and special-purpose pipes. Hot-rolled coil is also used to produce cold-rolled coil.
