HARRISBURG, Pa., March 11, 2011 (GLOBE NEWSWIRE) -- Worldwide industrial services and engineered products company Harsco Corporation (NYSE:HSC) announced today that its Harsco Metals group has been awarded two key multi-year contract renewals from one of Mexico's major steelmakers totaling more than $225 million in projected revenues.

The contracts, each close to ten years in duration and reflecting new and expanded commercial terms, extend Harsco's strong relationships with steelmaker Ternium México at Ternium's two Monterrey operations, Guerrero and Apodaca.

Announcing the contracts, Harsco Metals and Harsco Minerals Group CEO Galdino Claro said, "These are substantial, value-enhancing awards that reaffirm our long-term competitive opportunities in this emerging market region. The Mexican steel and metals sector is re-inventing itself with technical advances, continued consolidation and increased productivity. These objectives align well with our Harsco business model for innovation and technical leadership, and our overall strategies for further expansion within the world's developing economies."
