Siderpotenza, whose steel facilities were founded in 1963, has been part of the Pittini Group since 2002. The production site includes an electric steel mill and rolling mill for reinforcing bars for concrete.

The hot rolled steel bars meet the quality standards required by Italian and international regulations. Siderpotenza implements the “Zero Waste” project to recover and make the most of waste deriving from the manufacture and processing of steel, from which it obtains Granella®; a product used for road surfaces.

Green Steel is a project that the Pittini Group started in 2019, providing a series of measures with a common denominator: to protect the environment through the implementation of innovative technologies.
