If you are working on an outdoor project that necessitates a staircase, one of the major design choices you will face is what type of stair railing to include. At first the choice can seem overwhelming, as there are a vast number of materials and styles from which the average consumer is able to choose. But knowing the advantages and disadvantages of each material is the first step toward making an informed purchase. So take a look below at three of the most popular materials for use in building outdoor staircases, and see which one is right for you and your project.

Wood

Wood is one of the most popular choices for outdoor staircase railings, and for good reason. It adds an appropriately rustic character that simply isn't possible with aluminum or other inexpensive materials. It's also extremely easy to customize to your liking, as many types of lumber can be hand carved to a customer's exact specifications. One thing that should be kept in mind is that wood - like any other natural material - will deteriorate over time if not treated properly first. Make sure to seal your wood staircase railing every few years to protect against bad weather and ultraviolet rays. 

Metal

What wood railing lacks in durability, metal railing has in spades. If you're looking to invest in a staircase railing that will last the lifetime of the staircase (and then some), look no further. The other significant advantage of metal railing is that, like wood, it can be customized to match the color and style of your project. Many railings that appear at first glance to be wrought iron are actually constructed of less expensive metals. And if you're going for a sleek, ultra-modern look on your project, metal railings are usually the perfect fit.

Stone

If you're looking to achieve elegance above all for your outdoor project, then stone may be the best choice. Marble and granite staircase railings can contribute to a sophisticated look that's simply not possible with metal or wood. That said, it usually requires professional installation, and is a bit more vulnerable to the elements. But if you have the cash to spend and want your railings to match the rich decor featured in the rest of your staircase, stone railings are your best bet. Even if you're not looking to completely break the bank, you can still save by sourcing from local quarries in bulk.
