An ironworks or iron works is a building or site where iron is smelted and where heavy iron and/or steel products are made. The term is both singular and plural, i.e. the singular of ironworks is ironworks.

An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces and/or a foundry with or without other kinds of ironworks.

The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words sideros - iron and ergon or ergos - work. This is an unusual term in English, and it is best regarded as an anglicisation of a term used in French, Spanish, and other Romance languages.

Further processing[edit]

After bar iron had been produced in a finery forge or in the forge train of a rolling mill, it might undergo further processes in one of the following:
