US steelmaker Nucor has successfully produced its first prime coil on the new continuous galvanizing line at its Berkeley sheet mill in Huger, South Carolina, marking the completion of commissioning and the start of production. 

The new line has an annual capacity of approximately 500,000 tons and is designed to manufacture exposed automotive-quality steels and advanced high-strength steels (AHSS). Its product range includes galvanized, galvannealed, and zinc-aluminum-magnesium coated steels. 

Supplied by Primetals Technologies in partnership with Clecim, the facility features advanced cooling and induction heating technologies to meet demanding automotive requirements, supporting Nucor’s expansion into higher-value steel products.
