1957
Koç Trade Inc. (Koçtaş) was one of the biggest companies doing rebar business in 1950s and in those times rebar demand was supplied with imported steel products.
 
However, because of the foreign currency bottleneck rising after 1953 and of increasing number of quota requirements, the importation of rebar product become difficult.
 
Instead of direct importation, a system called provisory exportation was adopted which was carried out by exporting iron ore and importing refined steel products in return. Koçtaş resolved to initiate iron ore mining in order to sustain its steel sale.
 
Therefore, an association between Koçtaş and Tetico Technic Trade Co. was affiliated to our group in 1955 and equity of 500.000 Turkish Liras was allocated to extract iron ore, export it and import refined iron products into the country.
 
Afterwards, Sivas Çetinkaya and Otlukilise iron ore fields were taken over.
