CSC's manufacturing process is composed of raw material preparation, iron making, steelmaking, and rolling.

Raw material preparation
Coal, iron ore, and limestone are unloaded to the storage yard. Coal is then transferred to coke oven plants to produce coke; iron ore and limestone are transferred to the sinter plants to produce sinter.

Iron making
Lump ore, sinter and coke, together with fluxes are fed into the blast furnaces, to produce molten iron (hot metal) and slag. Hot metal is then transferred to the basic oxygen furnaces in railway ladle cars.

Steelmaking
Hot metal and steel scrap are charged into the basic oxygen furnaces to be processed into liquid steel, most of which is transported to the refining stations for further treatment, and then sent to the continuous casters to produce slabs or blooms which are semi-finished products.

Rolling
Blooms are fed into the billet mill to be shaped into billets and further processed into bars or wire rod products in the bar or rod mills. Slabs are fed into the plate mill to be rolled into plates or processed into hot rolled products in the hot strip mills. Hot rolled products can be further processed to produce cold rolled products in the cold rolling mills.
