Plating is a surface covering in which specific substances adhere to a smooth and even surface, giving a metal object underneath gold, rose gold or colorful finish.
Technically, it is a procedure that protects the metal from corrosion, in the case of stainless steel or other metals. However, the surface of these metal objects could still be harmed, leaving dents or scratches etc. They should still be treated carefully.
Glossy color metal balls, or shiny color metal balls, are metal hollow balls plated or painted with different colors. For gold and rose gold stainless steel balls, the color won't fade easily, compared to other colors.
