5 Most Popular Custom Metal Staircase Designs for Modern Homes & Businesses
Custom metal staircases are a top choice for homeowners, architects, and business owners looking for durability, modern aesthetics, and flexibility in design. Whether you prefer a sleek floating staircase or a grand curved design, metal staircases offer a strong foundation with countless customization options.
In this article, we’ll explore the five most popular metal staircase designs, their benefits, installation details, costs, and customization options.
1. Floating Metal Staircases (Cantilevered Design)
*Photos for example only, we did not create the above staricases*
Overview
Floating staircases create a sleek, modern appearance by making the steps appear to "float" without visible supports. These stairs are typically attached to a hidden metal frame or embedded into a wall.
Key Features:
✔ Open and airy design with no visible supports.
✔ Ideal for modern and minimalist interiors.
✔ Available with glass, wood, or stone treads.
Estimated Cost:
$10,000 – $30,000+ depending on materials, structural complexity, and customization.
Installation Details:
Requires a strong support wall or hidden metal framework.
Engineering and structural assessments are necessary.
Professional installation is recommended due to the complexity of the cantilevered structure.
Customization Options:
Treads: Wood, glass, stone, or metal.
Railings: Glass panels, cable railings, or sleek metal handrails.
Lighting: LED strip lights under each step for a futuristic look.
2. Spiral Metal Staircases

Overview
Spiral staircases are compact, space-saving designs that curve around a central support column. They are commonly used in lofts, outdoor decks, and industrial-style interiors.
Key Features:
✔ Great for small spaces.
✔ Can be installed indoors or outdoors.
✔ Classic and industrial designs available.
Estimated Cost:
$10,000 – $20,000 depending on materials, diameter, and railing options.
Installation Details:
Prefabricated spiral staircases are easier to install.
Requires a strong base and accurate measurements.
Can be DIY-installed if bought as a modular kit.
Customization Options:
Treads: Perforated steel, wooden inserts, or tempered glass.
Railings: Wrought iron, stainless steel, or powder-coated steel.
Colors/Finish: Black, bronze, matte, or glossy powder coatings.
3. Mono Stringer Metal Staircases
We did build the staircases in the photos above!
Overview
Mono stringer staircases have a single metal beam running underneath the steps, creating a sleek and industrial appearance. The open design enhances light flow, making spaces feel larger.
Key Features:
✔ Minimalist and modern design.
✔ Provides strong structural support with an open look.
✔ Great for commercial and residential spaces.
Estimated Cost:
$8,000 – $25,000 depending on materials and structure complexity.
Installation Details:
Requires custom fabrication and welding.
Structural engineering may be needed for large installations.
Best installed by professionals for safety and stability.
Customization Options:
Treads: Wood, steel plates, glass, or stone.
Railings: Horizontal cable rails, glass panels, or metal handrails.
Support Beam: Stainless steel, powder-coated steel, or custom finishes.
4. Double Stringer Metal Staircases
*Photos for example only, we did not create the above staricases*
Overview
Double stringer staircases feature two parallel metal beams supporting the steps on either side. This design provides extra stability while maintaining a modern look.
Key Features:
✔ More rigid and supportive than mono stringer stairs.
✔ Works well in commercial and high-traffic areas.
✔ Can be used for straight, L-shaped, or U-shaped staircases.
Estimated Cost:
$10,000 – $35,000 depending on materials and complexity.
Installation Details:
More stable than mono stringer designs but requires custom fabrication.
Engineering assessments may be needed for large spans.
Welding and heavy-duty fasteners ensure structural integrity.
Customization Options:
Treads: Wood, steel, concrete, or composite.
Railings: Glass panels, vertical metal balusters, or artistic designs.
Lighting: Integrated LED under-steps for a modern touch.
5. Helical (Curved) Metal Staircases
The staircase above was built by Fabwell Studios LLC in Rochester, NY while I was an employee there. We build and installed this staircase in Buffalo, NY.
Overview
Helical staircases (also known as curved staircases) have an elegant, flowing design without the need for a central support column, unlike spiral staircases. They provide a luxurious and dramatic effect in entryways and high-end spaces.
Key Features:
✔ Visually stunning and adds architectural appeal.
✔ More spacious and comfortable to walk on than spiral stairs.
✔ Custom fabricated to fit the space.
Estimated Cost:
$25,000 – $50,000+ depending on complexity, location, size, and materials.
Often the most costly option. Prices can sometimes range in the hundreds of thousands depending on the design, materials and complexity.
Installation Details:
Requires custom engineering and metal fabrication.
Needs structural planning to support the curvature.
Typically installed by expert craftsmen due to its complexity.
Customization Options:
Treads: Wood, glass, metal, or stone.
Handrails: Custom metal designs, glass, or wood.
Finish: Polished steel, powder-coated, or brushed metal.
