Operating costs for flatrolled minimill producers have dropped in 2019 as weaker steel markets have pulled down metallics prices. This has meant that operating costs for minimills are now in line with integrated producers in the USA. However, the current cost level is not expected to be maintained. US minimills are typically higher cost.

Benefits include: Greater Strength Coldrolled steel is about 20% stronger than hotrolled steel. When you pass the steel through rollers at low temperatures, it hardens and strengthens it. This makes it ideal for use in highstress applications. Better Surface Finishes Steel from cold rolling mills has a smoother and more uniform surface finish.
