- The Cedynia Rolling Mill Division of KGHM Polska Miedz S.A. produces 8 ± 0.4 mm copper wire rod using the method of continuous melting, casting and rolling.

- The surface of the wire rod is cleaned by the alcohol method and coated with a synthetic wax layer which protects the surface against oxidation during transport and storage.

- The wire rod has a uniform microstructure, with uniform oxygen distribution. Oxygen content is low enough to ensure good drawability and a low recrystallisation temperature.

- The Cedynia Rolling Mill Division of KGHM Polska Miedz S.A. holds an Integrated Management System Certi cate conforming to the following standards: PN-EN ISO 9001:2001, PN-EN ISO 14001:2005 and PN-N 18001:2004 for the products it manufactures.
