These homeowners couldn't pass up the opportunity to add some intrigue to their already warm and moody space with FLIGHT Spiral – a modern take on a classic spiral staircase, but with bolder design and materials. Not to mention the LEDs they had integrated into the helical treads.

Helical Treads
You know a Viewrail tread when you see one. Distinctive and modern, they bring natural wood tones and high-grade finishes that complement any space.
Our Spiral treads deliver that same quality in a unique helical design that’s bound to turn heads. Whether interior or exterior, get treads that show an unmatched attention to detail and elevated design.

Curved Rod Infill
Get rod infill that follows the curve of the stairs and keeps hardware hidden. At home inside or out, our rod railing is built to last, whether gracing a modern Midwest living room or standing up to the ocean air in the Hamptons.

Frequently Asked Questions
FLIGHT Spiral System
Yes. FLIGHT Spiral is a custom-prefabricated kit. We design, engineer, manufacture, and ship every component you need as one integrated system — treads, center structure, landing components (if applicable), railing, infill, and hardware — so everything is built to work together on site.
Each FLIGHT Spiral system typically includes:
-
Custom-engineered spiral structure
-
Helical hardwood or aluminum treads
-
Center support and connection hardware
-
Integrated railing posts
-
Stainless rod infill
-
Handrail, brackets, and terminations
-
Detailed engineering drawings and installation instructions
If you choose Viewrail Certified Installation, labor is coordinated separately but based on this complete kit.
FLIGHT Spiral is designed for tight footprints. Typical diameters range from about 5' to 10', which is significantly more compact than most straight or switchback stair layouts. Your design team will size the diameter and rotation to maintain comfortable walking lines and meet code while fitting the space.
In many homes, FLIGHT Spiral is engineered and permitted as a primary stair, provided it meets local code requirements for width, headroom, landings, and egress. In other layouts, it’s used as a dramatic secondary connection (to a loft, library, or roof deck). Our team will help design to your intended use.
Yes. Unlike old-school kit spirals with narrow wedge treads and just-adequate centers, FLIGHT Spiral uses helical treads and a rigid, engineered structure to create a wide, predictable walking surface and a no-wobble feel underfoot. When installed correctly, it’s a solid, everyday staircase.
Absolutely. You can tailor:
-
Tread species and stain
-
Powder coat or stainless finishes on the structure
-
Handrail finish
-
LED tread lighting
Stainless Rod Infill
Stainless (or Endurance) rod infill is our alternative to cable railing infill, and is the only infill designed to curve around the radius of the system. It uses hollow 1/4" 2205 stainless steel rods to deliver the same sleek, horizontal look as cable, but with better tension, easier installation, and superior long-term durability. The smooth surface minimizes places for corrosion to start, and each rod is engineered to stay rigid and secure over time.
Both stainless rod and cable infill are modern, low-profile options, but there are key differences:
-
No sagging: Rods are rigid, so they don’t develop the gradual “smile” that poorly tensioned or aging cable can.
-
Smoother surface: No braided grooves where contaminants can sit.
-
Curved and spiral friendly: Rods can be bent to follow curved and spiral layouts for a cleaner, continuous look.
-
Yes. Our stainless rods are made from 2205 duplex stainless steel, which offers significantly higher corrosion resistance than 304 or 316 in harsh environments, making it ideal for decks, exteriors, and many coastal applications when paired with the proper post and finish package. Always review your project location with our team for the best material recommendation.
For FLIGHT Spiral projects, Stainless Rod Infill is laid out, cut, and engineered as part of your kit:
-
Posts arrive pre-drilled.
-
Rods are provided to length with a straightforward installation process.
-
Hardware is either hidden or cleanly integrated for a minimal look.
-
You (or your installer) follow our project-specific drawings and installation videos.
Most crews find rod infill installs faster and with fewer steps than traditional cable.
Price, Installation, and Warranty
Pricing depends on diameter, floor-to-floor height, rotation, wood species, railing type, LED integration, and site conditions. Many FLIGHT Spiral systems with Stainless Rod Infill are anywhere from $15k to $35k. For current example projects and estimates, see the floating stair pricing guide and talk with our design team for a project-specific quote.
Yes. Our nationwide network of Certified Installers can handle the process from accurate site measurements to delivery and installation of your system, whether new construction or renovations.

FLIGHT Spiral is backed by a 10-year structural, and 5-year finish warranty.
Projects purchased with a Viewrail Installation Service Package also receive a separate 2-year labor & workmanship warranty.
FLIGHT Spiral systems are engineered to meet or exceed applicable residential code requirements when designed for your project and installed according to our specifications, covering guard height, spacing, tread depth and width, and structural performance. Because codes vary, we always recommend confirming details with your local building official using the stamped drawings we provide.
Yes. The easiest way to start the process is by requesting a quote to give us an initial idea of your project. From there, you'll work with a dedicated team to flesh out your design and custom engineer your project.
All floor designs start with the floor-to-floor measurement.
Measure subfloor to subfloor: from the top of the upper subfloor (where the header will mount) straight down to the top of the lower subfloor. A laser distance meter is ideal. Then gather any additional dimensions on the appropriate FLIGHT measurement form.
