The first company of the "Polytechnic Group" was established in Ankara in 1976. Engineering-time companies' time-lines are focused on the manufacture of large-diameter compensators and electrostatic filters. The "Polytechnic Group" opened a new production facility in Istanbul in 1988 by establishing a second company for the production of industrial type expansion joints.
