Is it better to use stainless steel or copper door handles?

Studies have shown that stainless steel handles are prone to breed bacteria, including E. coli, Streptococcus, Gram-positive and Gram-negative bacteria, etc. Because the door handle is a critical part of the door, spreading germs can be very detrimental to the user. Why are there much fewer bacteria on brass handles than on stainless steel handles? Copper has the effect of eliminating bacteria. In comparison, the survival rate of bacteria on copper door handles is low. After conducting many experiments, it was concluded that brass has All the bacteria will be killed in about seven hours. If it is a newly polished copper surface, the bacteria will be killed faster. Copper can not only sterilize, it is also corrosion-resistant, not easy to wear, has a long service life, and the copper handle is even more beautiful.

Sterilization of copper surfaces is divided into two steps: the direct interaction between the copper surface and the bacterial outer membrane causes the bacterial outer membrane to rupture; the copper surface acts on the holes in the bacterial outer membrane, and the copper ions cause the bacteria to lose necessary nutrients and moisture. , and eventually shrink. Copper can quickly and completely kill at least 90 species of germs on the contact surface, including 30 species of fungi and 20 species of viruses; and copper's bacteriostatic properties are long-lasting and effective, eliminating the opportunity for germs to regenerate! In order to protect the public health environment, especially It is best to use imitation copper door handles in public places such as stores, hospitals, stations, and airports, because brass can not only eliminate bacteria, but copper doors are cheap. Many people may think that copper doors are very expensive, because most of them can only be seen in banks. But in fact, the price of copper doors is not very high. For an average family villa, the price of a copper door only accounts for about one percent of the price of the villa. Taking into account other factors, copper doors are really cheap, high-quality and practical.
