Bronze screening

You can also get screening made from bronze wire that is 90% copper and 10% zinc, but this much more expensive than aluminum. At a higher premium, you can buy copper, brass or stainless steel. All of these except brass are typically made using a .011 wire size in an 18 x 14 or 16 x 16 mesh. Brass is made with heavier wire: .018 wire in a 16 x 16 mesh. Bronze is the least expensive, at about $1 per square foot copper and stainless are closer to $1.20. Brass is about $2.15 per square foot. When ordering specialty metals, expect a minimum order size of about $75.
When new, bronze has a golden shine. Copper, bronze and brass will eventually take on a verdigris patina stainless steel, the strongest, stays a shiny silver. Copper, bronze and brass should not be installed in aluminum screen door frames where the two metals touch, they will corrode.
