Jacksonville Floating Stairs fabricates structural steel stringer systems in-house using ASTM A992 wide-flange and HSS members. We cut, weld, and finish every component ourselves. Nothing is outsourced to a steel service center and shipped back misaligned.

Steel floating stairs suit Jacksonville's urban loft spaces in downtown, industrial-aesthetic homes in Riverside, and modern commercial builds throughout the metro. The material is honest about what it is — it doesn't pretend to be something else. Whether you want a visible industrial beam system or a slim mono-stringer that disappears into the wall, both are achievable with the right structural design.

In Northeast Florida, steel corrosion is a real concern — especially within a few miles of the coast. We use epoxy primer and polyurethane topcoats as standard for all exterior-adjacent steel, and we specify powder coat over wet paint for interior systems because it's more durable under daily contact. Near the beaches, we can apply additional galvanic protection if the staircase is exposed to exterior air.

Fabrication tolerance matters at installation. We work to 1/16-inch precision on stringer lengths and connection plate positions. That precision means field fit-up is tight without shimming or grinding. It also means wall penetrations and anchor bolt patterns land where they're supposed to, which keeps the surrounding drywall work clean.

How We Fabricate Steel Floating Stairs

Steel beam stair fabrication and installation in progress
01
Structural Design & Steel Section Sizing
We select steel section dimensions based on span, load, and deflection requirements. Stringer depth is minimized for visual cleanness without compromising stiffness.
02
In-House Cutting & Welding
Steel is cut and welded in our Jacksonville facility. Welds are ground flush at visible joints. Connection plates are welded in position — not field-bolted where it matters aesthetically.
03
Surface Preparation & Finish Application
Steel is blasted or ground to bare metal, primed, and finished. Powder coat, wet paint, or raw mill finish — we match the aesthetic to the project.
04
Field Fit-Up & Anchor Setting
Stringers are brought to the site and fitted against the wall. Anchor holes are drilled to the marked pattern, epoxy is set, and hardware is torqued after full cure.
05
Tread Installation & Touch-Up
Treads are set and fastened. Any installation marks or field welds are touched up. Final check covers alignment, hardware torque, and finish quality.
Project details

Why steel beam systems stay popular

Steel beam systems are direct. They handle long runs well, carry heavier loads, and give you more freedom when the wall can't support a pure cantilever layout. They also work well in commercial settings where traffic is heavier and maintenance expectations are different.

We can leave the steel visually present or make it disappear depending on the finish and the geometry. The point is not to force an industrial look. The point is to choose a structural strategy that fits the space and still looks intentional.

Included in the planning
  • Mono-beam and side-stringer options for different spans and layouts
  • Shop-fabricated steel with cleaner field installation and fewer surprises
  • Finishes ranging from exposed industrial character to low-visibility powder coat
Common Questions

Steel Floating Stairs — FAQ

Does steel rust in Jacksonville's coastal humidity?
Untreated mild steel rusts quickly near the coast. We address this with proper surface prep, epoxy primer, and protective topcoats. For exterior or semi-exposed applications, we use hot-dip galvanizing or 316L stainless for hardware. Interior powder-coated steel in a conditioned space performs well for decades without corrosion treatment upgrades.
What's the difference between a mono-stringer and a dual-stringer system?
A mono-stringer uses a single central beam. Treads cantilevered from both sides. It's a very clean aesthetic but requires deeper steel sections to control deflection. Dual stringers run along each edge of the tread and allow a thinner profile on each member. The choice depends on tread width, visual preference, and wall constraints.
Can steel stairs be painted to match my interior?
Yes. Powder coat is available in any RAL or custom color. We match paint colors to existing trim, cabinetry, or wall finishes on request. Most residential clients choose matte black, charcoal, or a warm dark gray. Custom colors are not an upcharge — they're just part of the finish specification.
How loud are steel floating stairs when walking on them?
Steel systems with solid wood treads are quieter than all-steel or glass-tread systems. Hollow steel treads drum more. We can install vibration-damping pads at tread-to-stringer connections to reduce sound transmission when noise is a concern in the home.
Is there a minimum tread thickness for structural steel floating stairs?
For wood treads on steel stringers, we typically use 2-inch nominal hardwood (about 1-3/4 inch dressed). For all-steel treads, plate thickness is determined by span and load. Duval County code sets minimum stair tread depth and rise height — we design within those parameters as a baseline.
