Metal deck railing is exceptionally stable. Because it doesn’t absorb water like wood or composite, metal doesn’t expand or contract the same way other materials do. That expansion and contraction can cause warping, and can slowly work fasteners loose over time. Metal railing, on the other hand, stays dimensionally stable for years in all types of weather. There’s a great feeling of security in choosing a metal railing for your deck - metal railing feels sturdy and strong to the touch.
Metal deck railing systems have also become extremely easy to install. Many come with pre-welded panels that anyone can easily attach to their deck in a single afternoon. Metal is also a strong stylistic choice with multiple color options and sleek, finished looks.
