History

TÜMAŞ's story spanning over 50 years is intertwined with Türkiye's own industrialisation and internationalisation. Founded in 1969 by Mr. Turgut Özal, our company became the first Turkish practitioner of the public-private partnership (PPP) model — long before that term gained global currency.
