Customer Collaborations

The need for countries and companies to be on a path to net-zero GHG emissions presents new opportunities for steelmakers. As an essential manufacturing material, steel supports the decarbonization of electric power generation, transport vehicles and residential and commercial buildings. These sectors are currently responsible for U.S. GHG emissions of 25%, 28% and 13%, respectively.*

In 2023, U. S. Steel established new customer relationships across diverse industries that support the transition to a lower-carbon economy. Several of these customers’ products support lower end-user emissions across their value chains.




U. S. Steel and DuPont launched a new product in 2023, COASTALUME™, North America’s first GALVALUME® solution engineered and warrantied for coastal environments. Marking a collaboration of two iconic American industrial companies, the new COASTALUME™ product combines the strength and self-healing characteristics of U. S. Steel's GALVALUME® solution with DuPont’s Tedlar® polyvinyl fluoride (“PVF”) film barrier that helps resist saltwater corrosion, UV damage, cracking, impact, and more.

Today, nearly 40% of Americans live in coastal counties and increasingly face unpredictability and damage caused by environmental factors such as hurricane force winds and saltwater spray. By combining these two materials for the first time, U. S. Steel and DuPont have built a maintenance-free roofing solution that offers a level of durability and reliability needed in residential and commercial construction along the coast.


BMW is focused on significantly reducing the carbon footprint of its steel sourcing, which is why they have partnered with U. S. Steel's Big River Steel to help them reach their sustainability goals. Purchasing lower carbon footprint steel from BR1 has “helped us achieve our current 100% renewable energy and lower CO2 footprint targets for 2024”, says BMW. About half of BMW’s flat steel requirements are supplied by EAF’s.

This manufacturing process has significant potential for CO2 savings, compared to coal-based steel production in a blast furnace. With its versatile properties, steel is nevertheless one of the key materials for automotive manufacturing and will be no less important for future vehicle concepts and generations.**



To meet the needs of today’s important applications, as well as to pave the way for tomorrow’s, we are constantly developing and improving innovative steel products — all mined, melted and made in America. Here are some of those products:
