It is the only integrated steel plant in Turkey capable of producing both long steel products (uzun urunler) and flat steel products (yassi urunler) simultaneously, giving it a structurally unique position in the domestic steel market.

Manufacturing is described as a continuous integrated production process incorporating modern production technologies and ongoing improvements; ancillary services include an online product catalog hosted at katalog.oyakmadenmetalurji.com.tr. Isdemir's go-to-market is direct B2B sales to industrial accounts; pricing is negotiated based on order volume, specifications, and prevailing market conditions, with no publicly disclosed price tiers. Distribution is single-country/domestic through direct sales and the online catalog, supplemented by sustainability and investor relations communications as primary marketing channels.

Revenue is generated through hardware sales of long and flat steel products to industrial customers in Turkey's manufacturing, construction, and automotive sectors. The company has stated a Net Zero carbon commitment by 2050 and publishes integrated activity reports from 2014 onward. Headcount sits in the 5,001–10,000 range.
