The Benefits of Choosing Spiral Stairs for Style and Space
July 31, 2025
If you’re looking for a way to add architectural flair, save space, and improve functionality in your home or outdoor space, spiral stairs are the perfect choice. From spiral outdoor stairs that connect your deck to your backyard to indoor spiral stairs that elevate your home’s interior design, these staircases strike the perfect balance between beauty and practicality.
At Great Lakes Metal Fabrication, we design, fabricate, and install spiral stairs that are both durable and stunning. Whether you need spiral stairs for a sleek, modern loft or custom spiral stairs for a unique project, we have the expertise to bring your vision to life.
The Benefits of Spiral Stairs
Spiral stairs are more than just a staircase, they’re a design element that transforms space. Here’s why they’re becoming increasingly popular for both residential and commercial properties over other options such as alternating tread stairs or spiral stair kits.
1. Space-Saving Design
One of the biggest advantages of spiral deck stairs and interior spiral stairs is their compact footprint. Unlike traditional straight staircases, spiral designs use a minimal amount of square footage, making them perfect for small spaces, lofts, rooftop terraces, and secondary access points.
2. Architectural Appeal
Metal spiral stairs instantly create a striking focal point. Whether you choose a sleek modern look or an ornate traditional design, these staircases add visual interest and sophistication to your property.
3. Durability and Longevity
When you choose steel spiral stairs from GLMF, you’re getting a staircase built to withstand years of heavy use. Our designs are engineered for strength and stability, with materials that resist wear, weather, and corrosion.
4. Versatility for Indoors and Outdoors
Whether you want exterior spiral stairs leading from your deck to your patio or indoor spiral stairs connecting two floors, spiral designs work beautifully in both environments. Outdoor installations use weather-resistant coatings, while indoor designs can incorporate wood, glass, or decorative metal touches.
5. Customizable to Your Style
With custom spiral stairs, you can choose every detail, from the type of metal and railing design to tread material and color. We can match your existing architecture or create a completely unique statement piece.
Types of Spiral Stairs
There’s no one-size-fits-all when it comes to spiral stairs. The right choice depends on your location, style, and intended use. Whether you need a functional outdoor staircase, a modern indoor focal point, or a fully customized design, we offer a wide variety of options to match your space perfectly.
Spiral Outdoor Stairs
Perfect for decks, balconies, and rooftop access, spiral outdoor stairs are built for maximum durability. Our designs use corrosion-resistant steel with protective finishes to withstand rain, snow, UV exposure, and fluctuating temperatures. Optional slip-resistant treads and weatherproof handrails make them safe year-round, even in wet or icy conditions. With multiple finish options, you can choose a style that complements your exterior without sacrificing performance.
Exterior Spiral Stairs
Exterior spiral stairs are ideal when you need to connect multiple levels without taking up valuable indoor space. They’re practical for accessing upper-level apartments, garages, or balconies while adding an architectural element to your exterior. We can incorporate decorative balusters, contrasting colors, and unique railing designs so your stairs enhance curb appeal while providing reliable access.
Spiral Deck Stairs
For elevated decks, spiral deck stairs provide a stylish and space-saving way to connect to your backyard, patio, or pool area. Their compact footprint preserves valuable space underneath your deck for seating, storage, or outdoor entertaining. Available in steel, aluminum, or galvanized metal, they combine strength with a visually appealing design that integrates seamlessly into your outdoor living space.
Metal Spiral Stairs
Metal spiral stairs are known for their strength, versatility, and low-maintenance design. They can be fabricated from steel, aluminum, or stainless steel, depending on your needs. Powder coating offers a durable finish in a wide range of colors, from sleek black and industrial gray to bold, modern tones. Pair them with glass, cable, or metal railings for a look that matches your vision.
Indoor Spiral Stairs
Perfect for lofts, attics, mezzanines, and tight spaces, indoor spiral stairs maximize functionality without overwhelming the room. They come in modern minimalist styles, rustic wood-and-metal combinations, or sleek industrial designs to fit your interior décor. With custom tread materials like hardwood, laminate, or textured steel, you can make them either blend in or stand out as a focal point.
Custom Spiral Stairs
When you choose custom spiral stairs, every detail is tailored to your vision. We help you select materials, railing styles, finishes, and tread types that reflect your personal style or branding. From ornate wrought iron for a classic look to sleek aluminum for modern appeal, your staircase becomes a unique feature that elevates your space both visually and functionally.
Steel Spiral Stairs
Steel spiral stairs offer unmatched durability, making them a smart choice for both residential and commercial projects. They are engineered for heavy use and built to last for decades with minimal upkeep. Steel stairs can be galvanized for superior rust protection outdoors or powder-coated for a clean, finished look indoors. Their strength, stability, and timeless appeal make them one of the most popular spiral stair options.
Are Spiral Stairs Code Compliant?
The answer is yes—when they are designed and installed correctly. Building codes in most areas allow spiral stairs, including spiral outdoor stairs, exterior spiral stairs, and indoor spiral stairs, as long as they meet specific safety and dimensional requirements.
At Great Lakes Metal Fabrication every set of custom spiral stairs we fabricate is built to meet or exceed local and national building codes. This ensures your staircase is not only beautiful but also safe and long-lasting.
Popular Uses for Spiral Stairs

Maintenance Tips for Spiral Stairs
To keep your metal spiral stairs in excellent condition, follow these simple tips:
- Clean Regularly: Sweep away dirt, leaves, and debris from steps and railings.
- Inspect for Damage: Check for rust, loose bolts, or worn finishes, especially on outdoor spiral stairs.
- Reapply Protective Coating: Keep your steel protected from the elements with periodic touch-ups.
- Tighten Hardware: Make sure connections remain strong and secure.
With minimal upkeep, your staircase will stay safe, functional, and attractive for decades.
Are Spiral Staircases Safe?
Yes, spiral staircases are safe when designed, built, and used correctly. Their safety largely depends on proper installation, adherence to building codes, and the user’s awareness while climbing. Because spiral staircases are more compact than traditional staircases, they have steeper treads and a tighter curve, which can make them slightly trickier to navigate—especially for children, elderly individuals, or anyone carrying large items.
Key Safety Factors:
- Building Code Compliance: A properly built spiral staircase should meet local code requirements for tread depth, railing height, and weight capacity.
- Quality Materials & Installation: Using durable materials like steel or hardwood and ensuring professional installation reduces risk.
- Handrails: Continuous, sturdy handrails are essential for safe use.
- Lighting: Adequate lighting helps prevent missteps, particularly on narrow treads.
- Intended Use: Spiral staircases are safest when used for secondary access (e.g., lofts, attics, decks) rather than as the primary staircase in a busy household.
Bottom Line: Spiral staircases are safe for everyday use, but they require mindful design and a little extra care from those who use them.
