Ayhan Tosyali

Ayhan Tosyali is vice chairman of steel and iron producer Tosyali Holding, which has 18 facilities spread over Turkey, Serbia and Algeria.

As a child, he joined his father and brothers in a small workshop in Iskenderun, where they made sheet metal out of used tin cheese cans.

From sheet metal, they went on to bucket and stove production. The family began investing in Algeria in 2008.

Including overseas operations, Tosyali is on track to become Turkey's largest iron and steel producer, with an 8.5 million ton capacity by 2019.

Ayhan shares ownership in the business with his brothers Fuat and Fatih Tosyali, who are also billionaires.
