When one thinks of medical institutions and healthcare facilities from a door hardware perspective, stainless steel abounds. What you may not know is that copper alloys such as brass and bronze, exhibit much more effective antimicrobial properties than stainless steel.
Numerous studies have been conducted throughout the past century, which demonstrate the effectiveness of copper alloys in minimizing the presence of E. Coli, Influenza A, Staphylococcus, and other microorganisms. Studies also show that ‘tarnishing’, or what we refer to as patina, has little to no effect on these antimicrobial properties. That is, so long as hardware touch-points are not lacquered or painted. As you know, we at SA Baxter love-love brass and bronze finishes and they way these finishes age so gracefully. The added benefit of these antimicrobial properties gives us all the more reason to love our brass, bronze, and copper finishes.
