Some facts ...
One of copper & zinc most outstanding characteristics is hygiene.
Copper is essentially antimicrobial, meaning it rapidly kills bacteria, viruses and fungi on contact. Antimicrobial zinc & copper is solid and durable, so it won’t wear away like a coating. Clinical trials in hospitals around the world have found that antimicrobial copper surfaces gather >80% less bacteria than non-copper surfaces, and this dramatic reduction means germs are less likely to be picked up and spread when people touch the surfaces.
Well-known manufacturers now produce frequently-touched objects – such as door handles, light switches and worktops –in copper wherever people gather and infections can spread, copper can help reduce the risk. Copper will naturally darken over time, but this does not make it less effective – in fact, it enhances their germ-killing properties and unique patina pleases the eye!
