Japan-based Kyoei Steel said it will further expand capacity at its US subsidiary, Vinton Steel LLC, raising planned annual output 360,000 short tons (an increase of 30,000 short tons) and rolling facilities to 360,000 short tons (an increase of 40,000 short tons).

The project involves new equipment from Tenova and upgrades to the rolling mill by Pomini. Kyoei Steel said the expansion aims to improve production efficiency and operational stability, strengthening Vinton Steel’s profitability. 

The company acknowledged that inflation, higher material and construction costs, and mutual tariffs have pushed investment costs above initial estimates. 

Total project investment is now expected to rise by US$72 million to about US$327 million. Construction is scheduled to start in April 2026, with the new melting shop beginning operations in March 2027 and full integrated production in October 2027.
