One of the main safety features of a staircase is the handrails and railings, which help prevent falls and injuries. These staircase parts can be made of different materials, but in comparison to other materials, steel is inexpensive both upfront and long-term. It does not require regular refinishing and is resistant to corrosion, which means it stands up against rust, water stains, and temperature extremes. Once you install a steel railing, you can rest assured it will maintain its appearance and structural integrity.
