Strip steel with a continuous coil thickness of about 20 mm or less (the maximum thickness is generally 25.4 mm) and with a width less than 600 mm is narrow strip steel, while strip steel exceeding 600 mm is broadband steel. The first hot strip mill was put into production in the United States in 1905 to produce strip with a width of 200 mm.

Various types of mills have been invented and put in production. A high crown (HC) mill with a work roll bending system was developed for control over strip flatness [7]. Based on a HC mill, a HCW (HC mill with work roll shifting) mill, which adds a work roll shifting system, can better control strip flatness in the hot rolling process.
