A rolling mill is a machine or factory for shaping metal by passing it between a pair of work rolls.

Rolling mills are often incorporated into integrated steelworks, but also exist as separate plants and can be used for other metals, and other materials.

Rolling mills historically have been of several kinds:
- Depending on the temperature of the metal being rolled, rolling mills are typically hot or cold rolling mills. Cold rolling is a Metal working process in which metal is deformed by passing it through rollers at a temperature below its Recrystallization temperature
- A slitting mill was used to cut flat bar iron into rods for nail-making. The slitting mill was a Watermill for slitting bars of Iron into rods QtubIronPillarJPG|thumb|right| Iron pillar at Delhi India containing 98% wrought iron]] Wrought iron is commercially pure Iron. In Engineering, Woodworking and Construction, a nail is a pin -shaped sharp object of hard Metal, typically Steel,
- A tinplate works normally contained at least two rolling mills, one for hot rolling and the other for cold rolling single plates, prior to tinning. Tinplate is sheet steel covered with a thin layer of Tin. Before the advent of cheap mild steel the backing metal was iron. Hot rolling is a Metalworking process where large pieces of Metal, such as slabs or billets are heated above their Recrystallization temperature and Cold rolling is a Metal working process in which metal is deformed by passing it through rollers at a temperature below its Recrystallization temperature
- From the Industrial Revolution, puddled iron, after consolidation with a powered hammer (shingling), was rolled into bar iron using a rolling mill with grooved rolls. The Industrial Revolution was a period in the late 18th and early 19th centuries when major changes in agriculture manufacturing and transportation had a profound effect on the Puddling was an Industrial Revolution means of making iron and Steel. Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 Shingling was a stage in the production of bar iron or Steel, in the finery and puddling processes QtubIronPillarJPG|thumb|right| Iron pillar at Delhi India containing 98% wrought iron]] Wrought iron is commercially pure Iron. The grooves provided were progressively smaller, so that on successive passes through the rolls, the cross-section of the bar became smaller and the bar itself longer. By designing the rolls appropriately, it is possible to obtain iron or steel with various cross-sections, including I-shaped girders and railway rails. I-beams (also known as W-beams or double-T esp in Polish and German) are beams with an I- or H-shaped A girder is a support beam used in Construction. Girders often have an I beam cross section for strength but may also have a box shape Z shape
