It is also the sole Ukraine manufacturer of cold-rolled galvanized sheets and car cylinders for compressed gas. Products made by this company are exported to more than 50 countries worldwide. This integrated mill has given birth to and supported development of heavy machine-building and tank-making of Mariupol city.

Working jointly with foreign companies, Ilyich Iron and Steel Works is implementing a reconstruction program involving continuous wide-strip hot and cold rolling mills to manufacture supreme-quality automotive sheets and plates.

The main types of rolling products embrace:

- hot-rolled strips made of low-carbon and low-alloy steels, 2.0-8.0 mm thick and 1,000-1,500 mm wide, in coils and 2,000-6,000-mm-long sheets (sheets can have lenticular and lozenge corrugation);

- cold-rolled strips, 0.2-0.5 mm thick, 1,000-1,350 mm wide, as well as 100-500 mm wide in coils, 0.5-2.0×1,000-1,350×2,000-3,000-mm sheets;

- cold-rolled and galvanized 0.5-1.0×20-60-mm bands;

- steel plates, 9-25×1,500-2,700-6,000-11,800 mm;

- two-ply, corrosion-resistant sheet steel clad with a layer of stainless steel, 8-30×1,000-2,100×6,000-11,500 mm;

- oil country tubular goods made of carbon and alloy steels, namely casing and drill pipes, as well as tubes for making of various-purpose cylinders.

Oil country tubular goods are made with outer diameter ranging from 219 to 325 mm and wall thickness of 8 to 20 mm. Tubes for dredge pump barrels have 24-80-mm thick walls. Heavyweight drill pipes are 178 mm in diameter and 44-49 mm in wall thickness.

Steel casting is currently reconstructed via mounting of a continuous caster in basic oxygen furnace shop and via introduction of finishing operations in cold and hot rolling mills.

This integrated mill has a workshop producing automobile and aircraft cylinders.
