We utilize state of the art technology to plate our copper sinks with nickel. This nickeling process has been taken to the highest level. Other companies offer nickel plated sinks; but inferior plating processes can lead to the quick deterioration of the nickel coating that derives from any number of sources, including dish soap! We know because we did the tests. Beyond the superior plating process, we offer a protective coating on our nickel plated sinks. This high quality two-layered plating and protection process prevents damage and deterioration of the nickel from common problems. This has lead to our new and innovative armored nickel products.
