Finally, metal stairs are the safest, strongest and the most versatile from a design point. There are two types of metal staircases, metal-only, and metal with accent materials. Metal-only stairs are what most people think when they hear of metal stairs. Metal-only stairs are very common for outdoor applications, industrial catwalks and parking lots. The accent materials are what make metal stairs more appealing in an interior setting.
Metal stairs with accents are very strong and versatile in design. In most cases, metal is the core material that gives unmatched safety and strength, and then an accent material such as wood, stone, or glass is used. This allows for unlimited creativity in design options. In modern and contemporary designs, it is very common to use metal structures with accented steps. Some examples are:
Metal structure with wood treads and handrail caps (treads can be butcher-block style with a mix of exotic woods)
Metal structure with stone steps and caps (granite, marble, quartz, and other commercially-available stones)
Metal structure with glass steps and/ or side walls (glass steps and side walls are very strong and offer quite a unique feature for the most sophisticated palates)
Not only do you get the strength and safety of the metal structure, but you also benefit from the style and beauty of accent materials.
