Aluminum is often called "bright wire" which refers to the shiny uncoated aluminum wire. Aluminum construction is long-lasting, streak-free and easy to maintain, making it an ideal screening solution for frequent use applications, including windows, doors, porches, gazebos and screen rooms. Strong and durable aluminum screening resists rust and will not sag and a protective finish prevents corrosion and strengthens the weave. The strong aluminum material is rigid enough to hold its shape during fabrication and the seasonal installation.
