The company was officially established in February 27, 1900. Then fitter Vilém Doležal set up a small fitter's shop and when Václav Těhník joined him, the public corporation "Doležal a Těhník, továrna na železné zboží a konstrukce" (hardware and structures factory) was founded in 1907. Before World War I the factory tended to provide rather manual work and most of the profit was immediately employed for company development, where trainees also worked. In the pre-war time manufacturing was expanded. However, during World War I the company did not manage to get any war contracts and the production was reduced after the war. Manufacturing significantly boomed between the wars. Two other companies were acquired under favourable terms which brought further company expansion, and in 1935 the company already employed 80 workers and 12 administrative employees; the number of workers more than tripled by the beginning of World War II. During World War II German management supervised the production of needed war stocks.

After World War II the company was pillaged The company employed 360 workers and 68 technical and administrative staff. At that time the company became again a private public corporation. From 1945 through 1948 the company was newly developed and production was restarted. At the end of 1948 the Doležal a Těhník private enterprise ceased to be a free business. It started to be supervised by Báňský a hutní podnik, národní podnik, a national corporation, as a Dolte branch plant in Prostejov. In 1949 the Moravské Železárny Olomouc organization was founded to which the Prostejov plant also belonged. Since 1949 the spring production was developed and after business nationalization the state started to invest in a spring shop in the company premises. In the 1950s a rail-switch building was erected and the production plan was stabilized. At the end of 1950s the spring and rail-switch production was stabilized. The so-called normalization time was tied with production development and stabilization.

In 1989 some discussions in the company clearly indicated the tendency to perform changes and restructuring, which were then slowly implemented. At that time the business had approximately 4,000 employees. In 1994 the company was privatized and split into three separate businesses and the privatization project was completed in 2000. Since 2005 the company has been a stable business with a growing share in the European market. In May 2008 the original shareholder sold the company to the Moravia Steel, a.s. steel group.
