Rautaruukki Corporation (, using the marketing name Ruukki) is a Finnish company, headquartered in Helsinki, which manufactures and supplies metal-based components and systems to the construction and engineering industries.
The company was founded in 1960 by the Finnish Government to provide the steel supply needed by the nation's heavy industries. Since part-privatization in 1994, the state has gradually decreased its holding in Rautaruukki to 40% and the firm is now a constituent member of the OMX Helsinki 25 index 1. The name of the corporation means simply ironworks in Finnish.
The firm consists of three business areas: construction, engineering and metals. Rautaruukki produces a range of products for clients in various industries, including cabins and chassis for heavy vehicles, hot rolled steel plates and coils, roofing sheets and building and bridge structures.
The company employs around 11,800 people, e.g. in the Nordic countries, the Baltics, China, Russia, Ukraine and Central Eastern Europe.
