As the increasingly demanding container and silo industry enquires Ra-values < 0.20 µm, mirrorINOX offers now the new toRa-Finish. The wet-polishing process avoids the built-up of heat in the material, that often occurs when dry grinding. Maximum dimensions up to 4,000 x 16,000 mm, as well as Ra-values below 0.025 µm (so-called N1 degree of roughness) are possible.
