Inland Steel and Altos Hornos de Mexico said the new company, Ryerson de Mexico, will provide materials handling services to their customers in Mexico. It will be based in Monterrey, Mexico.

They estimated that Ryerson de Mexico initially will generate $100 million in revenues annually. The partners will share equally in the company's financial results.

The joint venture will specialize in inventory management, distribution and logistics of transporting metal and other construction materials, Inland spokesman Robert Weidner said.
