About U. S. Steel

U. S. Steel is focused on profitable, sustainable steel solutions for people and planet. Our goal is to make U. S. Steel a stronger, more agile company.

Our USW-represented facilities are a key part of our footprint and U. S. Steel has continued to enhance the competitiveness of our USW-represented facilities, investing $5.3 billion over the past five years. 

With our industry-leading coating and finishing lines we are well equipped to provide customers with the most advanced steels – steels that are Made in America. 

U. S. Steel also continues to fight for securing and maintaining a level playing field on trade. Recently, the U. S. International Trade Commission voted to continue eight anti-dumping and countervailing (AD/CVD) duty orders on cold-rolled steel from five countries. This important victory reflects U. S. Steel's dedication to working with the federal government to maintain the competitiveness of our industry. 

Profitable Steel Solutions for People and Planet
A Sustainable Future

Teams at our USW-represented facilities are finding ways to optimize processes to offset carbon emissions. And we are intently exploring carbon-capture alternatives to potentially be used at our blast furnaces. We are also using research, innovation and collaborative relationships to make sure U. S. Steel is positioned to leverage technological advances in sustainability to make our integrated assets more carbon-friendly as the technology becomes available.

We are moving to a sustainable future in line with customer and government expectations. Our customers are on their own sustainability journeys, and they are asking the same of their suppliers. This is how we stay competitive in the industry. 


We are an industry leader in worker safety -- as evidenced by our record-setting performance in our Days Away from Work metric, which is currently at 0.03.
