The steel plant consists of five product lines at three facilities, in Dörtyol, Iskenderun and Istanbul, for the processing of different flat steel products:

Service center

Two service centers are in operation, in Iskenderun and Istanbul. They are equipped with a hot shear line and a combined cold shear and slitting line. At the hot shear line, steel coils of 1–8 mm (0.039–0.315 in) thickness and 800–1,600 mm (31–63 in) width can be cut to sheets of 1,000–8,000 mm (39–315 in) length. The combined line is capable of processing coils with material thickness of 0.25–3 mm (0.0098–0.1181 in) and width of 800–1,600 mm (31–63 in) to slices of minimum 60 mm (2.4 in) width and 500–6,000 mm (20–236 in) length.

Continuous pickling line

At the continuous pickling line located in Iskenderun, coils of 1–5 mm (0.039–0.197 in) thickness and 800–1,600 mm (31–63 in) width can be processed for pickling. The line's annual capacity is 1,200,000 m (3,900,000 ft).

Cold reversing mill

Steel coils of 1.5–4.5 mm (0.059–0.177 in) thickness and 800–1,530 mm (31–60 in) width can be cold reversed at the mill in Iskenderun. The line's annual capacity is 750,000 m (2,460,000 ft).
