The preparation of the surfaces is to facilitate the depositing of the chrome, eliminating any substances on the piece's surface, via
degreasing and washing processes.
Sanding is used to deep clean the surfaces to be treated or to give the surfaces a certain roughness.
Electrolytic dechroming is available, for removing chrome from pieces to be reconditioned.
Superfinishing aims to reduce the roughness of the chrome plated surface, giving the calender cylinders a specular quality.
