ProBuilt railings are fabricated using the latest technology in aluminum alloys and exterior metal coatings. Paint is formulated to exceed the toughest standards in the industry. The result is no rusting, rotting or repainting and low maintenance. In fact, we guarantee that the standard ProBuilt factory paint finish on our residential aluminum railings will not split, flake or blister for as long as you own your railing.
