Wood is the cheapest metal railing material costing $20 to $60 per linear foot installed. Wood is prone to water and pest damage when exposed to the elements, so outdoor use is not recommended. When most people think of a wood railing, they picture an outdated oak staircase railing with turned wooden spindles, but there are much more visually appealing wooden railings available to suit farmhouse, industrial, and even modern homes.
If you want the high-end look of glass or cable railings without the high price, mixing materials is a great way to save money and make an old wooden railing look more up-to-update and contemporary. Adding black metal accents or cable balusters can completely change the look of a wooden railing.
