ÇOLAKOĞLU METALURJİ A.Ş

Company Profile

It’s 1945 and our story begins in a shop in İstanbul’s Karaköy district which dealt in iron and steel and which belonged to Mehmet Rüştü Çolakoğlu, the founder of our company. The business did well and towards the end of the 1950s the first Çolakoğlu® steel mill commenced operation in İstanbul’s Sütlüce district. Growth was inevitably fueled by the need to keep pace with the steadily increasing importance of billet steel as a basic material. In 1969 Çolakoğlu began producing steel in its mill in Dilovası, a town on the Gulf of İzmit east of İstanbul. Since the very outset, Çolakoğlu has always maintained its leading position in its sector by undertaking new investments. In 1985 Çolakoğlu became the first privately-owned firm in Turkey to produce wire rod. In 1990 it added steel reinforcing bar to its product line
