The history of our company begins in 1982 with the establishment of Petrotech – Petrochemical Plants. In the beginning, the company sold pipeline valves for power plants, heating plants, chemical plants and as well as for the gas and oil industries. Already at that time the focus was on the Export, mainly to Hungary and Poland, and this was soon followed by the expansion of activities to include trade in steel products such as pipes, fittings and sheet metal.
From 1989 to 1999, 50% of Petrotech was owned by DKG East RT., the largest Hungarian petroleum industry valve manufacturer at that time.
Into the future with Steel Line
In 2000, Steel Line, under the leadership of Karl Kainz, acquired 100% of Petrotech. Under this new management, Petrotech’s steel trading activities were stepped up further – with success, as the company quickly established its own sales offices in Germany, Poland and Turkey.
In 2005, Steel Line and Petrotech finally merged into one company and the headquarters were moved to Vienna-Floridsdorf. Due to the continued success, a further representative office was opened in Romania in 2010.
