Çolakoğlu’s involvement in the iron and steel business began with the steel trade business that our founder Mehmet Rüştü Çolakoğlu started in Karaköy, İstanbul, in 1945. The first Çolakoğlu rolling mill commissioned in Sütlüce, Istanbul, in 1960. The first meltshop went into production in Dilovası in 1969 to supply billets to the domestic market. The company now called Çolakoğlu Metalurji strengthened its sectoral leadership when it started wirerod production in 1985. In 1990, Çolakoğlu added reinforcing bars to its production line. Çolakoğlu Metalurji proved its determination in its efforts to bring state-of-the-art technologies to Turkey by investing in a new meltshop and rolling mill for flat products in 2007. At the time the meltshop was commissioned, it had the world’s largest electric arc furnace. Çolakoğlu Metalurji also made the first hot-rolled strip investment of the private sector in Turkey.
