STEEL CHROME PLATED Chromium plated collars by Herm. Sprenger stand out due to the high-gloss surface. They achieve this result by not only cleaning the raw chain from metal debris and oil, but also through their own process which gives the collar a special surface polish. Elaborate processing methods and quality control guarantees both an excellent chromium plating, and combined with the prior process of nickel coating also provides a dual anti-rust protection. Damage however, occurring to the surface of the chain by external influences, can make the metal core vulnerable to water ingress and variation in temperature. It is for this reason that they cannot undertake a rustproof warranty for any products made of plated steel, regardless of the surface finishing. Nickel and chromium baths are monitored constantly by a laboratory and are disposed of according to the current environmental laws and regulations
