The rod surface treatment is the most critical single determinant of lift cylinder service life in contaminated or corrosive environments. Hard chrome has been the standard for decades \u2014 but increasing environmental regulations on hexavalent chromium plating, combined with the availability of superior alternatives for specific applications, has expanded the selection decision into a genuine engineering choice. This guide covers the principal lift cylinder rod surface treatments, their performance characteristics, and the selection criteria that determine which is correct for each application.<\/p>\n
