If you need an affordable metal stair railing option for your Phoenix home, aluminum might be a good choice. It’s less costly than your stainless steel or wrought iron stair railing options. Aluminum being naturally resistant to corrosion or rust it’s a great option for both outdoor and indoor applications. Aluminum stair railings also have a very good strength to weight ratio, so they are good for strong but light installations. You can get an aluminum stair railing with a polished, muted satin or even painted finish. As with most polished metal surfaces you will have a bit more maintenance to keep it looking good. A muted satin finish on your metal stair railing will help hide fingerprints. Painted aluminum stair railings are a great option if you have a color scheme already going with your interior design.
