Published 10th December, 2025 by Pete Downham

US Steel will restart one of two blast furnaces at its Granite City Works in Illinois to meet customer demand.

David B. Burritt, CEO of US Steel, outlined that the decision was made after months of analysing customer demands.

Burritt added: “Steel remains a highly competitive and highly cyclical industry, but we are confident in our ability to safely and profitably operate the mill to meet 2026 demand.

“We look forward to partnering with all stakeholders, including the United Steelworkers and elected officials, to ensure a safe and efficient start-up and to discuss support for Granite City Works.”

US Steel remain committed to reaching net-zero greenhouse gas emissions by 2050.
