A CM sink brings light and shine to your kitchen. The label issued by the Italian Stainless Steel Development Association, certifies our AISI 304 18/10 stainless steel, whose main characteristic is that it does not corrode if exposed to air or water. Stainless steel has a unique property: it is self-protecting. A fine, transparent patina forms on its surface, thanks to the alloy elements. If the surface is scratched or damaged, this thin, passive layer, made up of just a few atoms, instantly re-forms thanks to the action of oxygen in the air or water. This explains why stainless steel never needs coating or other types of protection to keep its brilliant shine. Even after decades of use.
