A roof deck with no room for a straight run from the back patio
Leander Metal Gates is the metro's trusted expert in iron staircases, specializing in steel spiral stairs, straight stringer stairs and oak-tread outdoor stairs. We offer roof deck and patio access stairs and interior feature staircases built around the room they serve.
Our team provides stair layout, landing design and powder-coat finishing for residential and commercial buildings. The business has run for 14 years, carries a 2-year workmanship warranty and has finished over 1,127 projects, from a short garden stair to a 300 ft retail back lot with a service stair.
From measuring the rise to bolting on the final tread, our team handles each staircase. Serving Leander and neighboring Georgetown, Round Rock and Cedar Park, a stair is handled as structure first and as a design feature after that.
Call for a free estimate: we measure the rise, check the landing and quote a price per staircase before any steel is ordered.
Numbers first
The hard part of many stairs is not building them but delivering them. A spiral that stands 11 ft in The Hills is too big to carry through a door in one piece, so we build it in sections, carry them in and assemble them with bolts on site. That keeps welding and sparks out of the finished home, and it means a spiral for a roof deck in Lakeway or West Lake Hills arrives clean and is finished before it is lifted.
Before anything is ordered in Volente or Lakeway we walk the route from the driveway to the stair location, measuring every turn, door and landing the pieces will pass through. A tight hallway in Cedar Park or Georgetown can decide the shape of the stair before the design does, and a hillside lot in The Hills can decide where the footing goes.
The finish for a Steiner Ranch stair is applied before assembly in the shop: blast, zinc primer, then polyester powder cured in the oven, with touch-up kits left on site for later scratches. Scratches from carrying the pieces in are then touched up after the bolts are tight.

Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Vivian's roof deck in the Flintrock neighborhood of The Hills, a hillside address, had no room for a straight run of stairs. We built a steel spiral with oak treads, 5 ft in diameter, to climb an 11 ft rise, bolted it together on site and sized the landing so chairs could be carried up. The job was an estimated $3,700 to $5,500 and took an estimated 2 to 3 days.
A stair is a structural job, and the risks sit in the numbers: how deep the tread is, how high the guard stands, how much headroom the opening leaves and whether the landing is large enough to turn on. We draw these on the plan, and a stair guard along the open side is priced at an estimated $66 to $134 per linear foot in Round Rock and Steiner Ranch alike. We confirm the stair code, the headroom and any engineering stamp with the city before steel is cut.
Leander sits in both Williamson and Travis Counties, so the side of the county line can change who reviews a stair. An exterior stair near a creek or a lot line in Georgetown or Round Rock may also need review, and we ask the city instead of guessing.

A spiral, estimated at $1,400 to $5,900 per staircase, uses the least floor space and suits a roof deck or a loft, while a straight stringer stair is easier to climb with a load. The table compares them, and the treads can be oak for warmth or powder-coated steel for an outdoor stair that sees rain.
| Stair type | Est. investment | Best use | Footprint |
|---|---|---|---|
| Steel spiral stair | Est. $1,400 to $5,900 per staircase | Roof decks and lofts | Small circle |
| Straight steel stringer stair | Est. $66 to $134 per linear foot of guard | Patios and level changes | Long run |
| Hand-forged feature stair | Est. $86 to $129 per linear foot of guard | Entries and formal rooms | Long or curved |
Every stair in Cedar Park or Sunset Valley needs a guard at its edge, and our iron railings are drawn together with the stair so the two read as one piece. For a deck that sits above a drop, see iron balconies.
A steel spiral stair is estimated at $1,400 to $5,900 per staircase and typically takes 1 to 4 days, and the guards along a straight stair are priced at an estimated $66 to $134 per linear foot.

A long single leaf with one arm and a keypad, for builder-lot drives with room on one side
A centered pair with two operators, for wide openings and a drive that stays level behind the line
One leaf running on a floor track, for a flat drive with side room and no swing space
A counterbalanced leaf on enclosed carriages, for caliche, crowned drives and heavy daily use
A person-width steel gate with a keyed latch, for walkways, side yards and courtyards
Motor, photo eyes and remotes fitted to a leaf that already hangs true
From a coded keypad to video calling, with visitor and courier codes set up
Welded panels in a 4 to 6 foot height, set on concrete posts with racked or stepped sections
Hammered pickets and collars at 5 to 6 feet, for period homes and estate frontage
Aluminum barrier at the height we confirm with the city, with a self-closing, self-latching gate priced apart
Blast to bare metal, treat rust and refinish, for sound iron with a failed finish
Steel or iron guards measured at the site, anchored to the stringer or the slab
Compact steel or iron spiral, with headroom and landing checked before anything is ordered
Steel or iron door with insulated glass, sized to a new or existing rough opening
Recurring visits for operators, safety devices and hinges, with a written service log
Steel slat panels and matching gate infill, priced by the run once the slat gap and height are set
Stainless cable on steel posts for decks and balconies, tensioned and checked at handover
Tempered glass panels with steel posts or a base shoe, set once the measured panels arrive

| Job | Est. investment | Est. duration on site |
|---|---|---|
| Spiral stair | Est. $1,400 to $5,900 per staircase | Est. 1 to 4 days |
| Stair or balcony guard | Est. $66 to $134 per linear foot | Est. 5 to 10 hours |
| Hand-forged iron work | Est. $86 to $129 per linear foot | Est. 3 to 6 days |
The diameter, the rise and the tread material move the price more than anything else, and a hand-forged feature stair adds days at an estimated $86 to $129 per linear foot of guard. A short spiral with powder-coated steel treads lands near the bottom of the estimated $1,400 to $5,900 range, and a tall spiral with oak treads and a large landing lands near the top. Treat these as Leander estimates, subject to change with the rise, the access and the finish. Once the stair is measured on site, your quote states the final price and the install schedule in writing.
We build stairs across a 35-mile radius, with most of the work in Cedar Park, Georgetown and Round Rock. Because most Leander homes are recent, an exterior stair here is usually a new feature for a deck or a patio. The Hills, Lakeway and West Lake Hills homes often have roof decks and hillside patios that need stairs built to the slope. See the service area page for the other towns on our route.

We bolt each stair together on site in Cedar Park and Volente, so a spiral that cannot be carried whole still arrives straight. After 1,127 projects over 14 years, we know where a landing is too small and a rise is too tall. The workmanship warranty runs 2 years on welds and plumb.
See iron railings, iron balconies and wrought iron gates.

A steel spiral stair is estimated at $1,400 to $5,900 per staircase, depending on the diameter, the rise and the treads.
A spiral typically takes an estimated 1 to 4 days on site, and Vivian's roof deck stair in The Hills took 2 to 3.
The one we built in The Hills was 5 ft in diameter, and the diameter is set to your room and your code.
Yes, that is the usual reason for one, and the landing is sized for the people and furniture that will use it.
Often yes for a stair, and we confirm it with the city before the drawing is signed.
We build it in sections and bolt it together on site, so it fits through the door.
Ask for a free estimate and we will take the rise measurements, inspect the landing and put the price per staircase in writing.



The order of work
We tape the opening, check the wall or slab and read the town rules before anyone prices steel.
You sign one scaled sheet listing size, coating and spacing, and that sheet doubles as your review board packet.
Each piece is welded in the shop and coated before delivery, so no grinding or spray paint happens at your home.
Anchors go in, the piece is fixed in place, and we check plumb and spacing with you standing there.
