Seven-Diamonds Steel Complex established in 1996 to produce hot dipped galvanized and cold rolled steel coils. Civil Operation Started in 2001 and production of hot dipped galvanized sheet successfully achieved in 2003 with the annual capacity of 100 000 ton.
Seven-Diamonds not only known as a leading producer of HDG in local market, but also it’s products being exported to Middle east, European countries and international markets.
Second Phase of Seven-Diamonds project is to set up cold rolled production with annual capacity of 800 000 ton. The first stage of this phase is production of 300 000 ton/year cold rolled steel which is successfully installed in 2007. The quality of the produced coils is competitive with production of international markets. The next step is production of 500 000 ton/year cold rolled steel which is going to be installed in near future.
