The plant will feature latest SMS group technology for high-speed bar mills and tying equipment, such as:
- HSD® (High Speed Delivery) system which stands for increased productivity and maximum yield at high speeds of up to 35 m/s
- Fully automated tying machines with energy consumption reduced by about 50 % compared to the old-design compactors.
Established in 1954 as Daehan Trading, the company was mainly active as a wire rod producer and in the 1970s started to produce steel bars due to a rapid growth of the Korean economy. Over the years, the company became a specialized steel producer. In 1992, it changed its name to Daehan Steel and emerged as one of the most important steel producers in the Far Eastern countries. With the present investment Daehan Steel will expand its possibilities on the local market and in the neighbouring countries.
