YEŞİLYURT DEMİR ÇELİK, a family company, switched from being a trader, a profession inherited from their father, to an industrialist with its bar rolling mill with a capacity of 100,000 tons per year, established in Karabük in 1980. In 1987, second bar rolling mill with a capacity of 420,000 tons/year was established in Samsun and a steel mill with a capacity of 420,000 tons/year was established in 1997.

Continuing its way as the pearl of the Black Sea, Yeşilyurt Steel opened its own steel mill with a capacity of 420,000 tons/year in 1997 to produce its own semi-finished products due to supply problems in billet. Aiming top tiers of world steel production, YEŞİLYURT -through modernizations- increased its rolling capacity to 900,000 tons/year, and its liquid steel capacity reached 1,300,000 tons/year. All grades of ribbed rebar are produced in the range of 8mm to 50mm in the rolling mill.

Yeşilyurt Demir Çelik is among the first 100 companies in the list of Turkey's 500 largest companies, announced annually by Istanbul Chamber of Commerce and Industry.
