GEM is recognized as a leading supplier and innovative developer of stainless steel products that add value, function and style to some of the finest recreational boats in the world. We are the creators of the GEMLUX Electropolishing Process. The process removes iron from the surface of the steel yielding a higher chromium to iron ratio which gives our hardware an unmatched luster and resistance to corrosion.
