Choose your patio screen material based on three things –location, budget, and utility.
If you are located near a beach, then a standard aluminum screen will oxidize quickly. But if budget is a significant concern, then aluminum is the way to go. If money is no object, monel, copper, and stainless steel are the usual choices in metal patio screens. Other alternatives include fiberglass mesh –fairly inexpensive and glare-resistant.
If you are basing your choice of patio screen purely on function alone, then we suggest using either a sun-control mesh or a pet-resistant variety. Both options can be a little expensive, and we recommend using them judiciously.
