The current shape of the Company was shaped in 2016, as a result of the transfer of the Siedlce plant to a separate company. Mostostal Siedlce started its activity in 1973 as Wytwórnia Lekkich Konstrukcji Stalowych. At the end of the 1970s, the production of steel structures (1975), platform gratings (1977) and the hot-dip galvanizing plant in Siedlce (1978) were launched. The turn of the century is a time of change and progress for Mostostal Siedlce: 1993 - privatization of the company, Mostostal Siedlce SA begins operations 1997 - Mostostal Siedlce debuts on the Warsaw Stock Exchange 1999 - a majority stake in Mostostal Siedlce is bought by Polimex-Cekop, whose history of operations dates back to 1945 2004 - a merger of Polimex-Cekop and Mostostal Siedlce, followed by the creation of Polimex-Mostostal Siedlce SA 2006 - change of the company's name to Polimex-Mostostal SA 2016 - separation from the structure of Polimex-Mostostal SA of the plant in Siedlce as Mostostal Siedlce Spółka z ograniczoną odpowiedzialnością Sp. k.
