Customers can find iron railings for outdoor steps at Home Depot and Lowe's. Smaller companies, such as Artistic Iron Works in Las Vegas, Nevada, offer customers custom-built iron railings for outdoor steps.
As of 2015, Lowe's sells a variety of iron balusters for outdoor stairs by House of Forgings. These balusters are hollow and come in 44- or 42-inch models. They are also available in a number of intricate designs or as straight black pieces.
Home Depot offers a number of railings by Village Ironsmith available in 4- or 6-foot sections. The pieces come in classic or metropolitan design. The iron handrails available from Artistic Iron Works are sourced from iron workers in the Las Vegas area and come with a full warranty. Wrought Iron Solutions, LLC in Ripon, Wisconsin, and Southeastern Ornamental Iron Co. in Jacksonville, Florida, also offer iron railings for outdoor steps.
