Mirror Polishing

Mirror polishing of Duplex stainless steel is carried out by our workers in Posidonia's workshop and is a manual operation using tools. It is a mechanical action that allows obtaining a high-quality finish so that the body in question shines with reflected light. It is a precise and very delicate operation if a quality result is desired. Low-speed abrasive amalgams are used to slowly remove scratches and imperfections from the metal, resulting in a smooth surface and the anchor or deck equipment becoming shiny and mirror-like.

In more technical terms, steel with a mirror finish will have an Ra reading of less than 0.2, or average roughness. Roughness (Ra) measures the microscopic peaks and valleys in the surface of the metal: the lower the number of these peaks and valleys, the smoother and more reflective the metal surface will be.
