everything in one complex – from putting together raw material to steel making,
rolling and shaping. Mini Steel Plants are smaller, have electric arc furnaces,
use mainly steel scrap and sponge iron as inputs. They have re-rollers that use
steel ingots as well. They produce mild and alloy steel of given
specifications.
