Up to 2010 Çolakoğlu Metalurji’s production was focused on long products, namely, billets, reinforcing bars, wirerods and debars in coils. With its half century of experience in steel production, Colakoğlu has now added hot rolled coils to its product range and has started addressing higher value-added segments such as pipes, automotive, white goods, machinery and structural steel. Its 3 million mt crude steel capacity meltshop enables it to produce 2.5 million mt of billets or 3 million mt of slabs. 3 million mt of Colakoğlu’s hot rolling mill capacity is currently in use. Its hot rolled coil production capacity may reach 4.5 million mt with additional investments. Colakoğlu’s meltshop is among the most modern crude steel production plants in the world. Production is made with one of the largest electric arc furnaces in the world of 320 mt casting capacity. The company 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. With its seven-stand line, Çolakoğlu’s facility is able to produce a wide range of materials from low carbon steels suitable for cold forming up to oil and gas pipes, in thicknesses of 1.1-25.4 mm and widths of 800-1,650 mm.
