1. Galvanized Steel Roll description
Steel strip is a steel product that is produced from a hot rolled strip that has been pickled. The
coil is then reduced by a single stand cold roll steel mill straight away or reversing mill or in a
tandem mill consisting of several single stands in a series steel strip is reduced to approximately
final thickness by cold-rolling directly, or with the inclusion of an annealing operation at some
intermediate thickness to facilitate further cold reduction or to obtain mechanical properties desired
in the finished product
