Want a steel staircase? We’ll draw it for you and the fabricator
Zigzag steel stringers with the treads lying on the cut string, oak or steel, straight, L-shaped with winders, U-shaped or spiral. Tell us the floor height: uCAD works out the risers and the going and draws every tread, stringer, post and bar at its real size.
Work out the steps
Steel stairs of every shape
What it draws
- Stringers as you choose: zigzag (cut) steel strings under the treads, closed strings with the treads housed in them, or solid steps.
- Treads with a nosing; open, or closed with risers.
- Posts under the landings and the turns.
- Railings: a handrail 90 cm over the nosings, bars no more than 11 cm apart, newel posts at the ends.
- Colors for the treads, the steel and the bars: black steel and oak, all galvanised, white powder-coat.
For the fabricator
- Every part at its real size: measure a stringer, a tread, the run, with the tape measure.
- Explode the stair to see its parts; each tread and bar is its own solid.
- Export it (STL, OBJ, glTF, DXF) or send a link the workshop opens without signing up.
- Put it in the building's model: the floor opening, the headroom, the landing at the top.
Tell us what you need. We’ll do it.
uCAD’s AI draws it in real sizes, and changes it when you ask.
Can’t make the furniture fit?
We’ll lay it out for you, every piece at its real size.
Want a new kitchen?
We’ll design it: the units, the worktop, the appliances, to your walls.
Not sure the staircase will fit?
It will: we work out the steps from your floor height and show you.
Love a house, a garden or a room you saw?
Show us the photo: we’ll build one like it, to real sizes.
Building a shelf, a bench, a workbench?
You get the cut list, what to buy and how to put it together.
Need a floor plan?
Tell us the rooms: we’ll draw the flat or the house, walls, doors and windows.
You say it, we draw it
No CAD to learn: write what you need the way you’d tell a builder or a designer.
Not right? Say so
“Move the sofa to the window.” “A metre wider.” Every change can be undone; nothing can break.

Questions
Do I need to know CAD?
No. Say what you need and uCAD’s AI draws it; ask again to change it. The drawing tools are there if you’d rather do some of it yourself.
What does the AI cost?
A new account tries it free. After that it comes with uCAD Pro ($19.99 a month); building after a photo, a sketch or a plan is in uCAD Studio ($49.99 a month). Drawing by hand, importing and exporting stay free.
How exact is it?
Every part has its real size, and you can measure anything. If the AI gets a detail wrong, tell it, or fix it by hand.
Can I make the treads steel too?
Yes: paint the treads steel grey, or checker plate grey; the spiral's are steel by default.
Does it follow the building code?
It works out a comfortable stair (risers up to 18 cm, a 63 cm stride), inside the usual codes for homes; check the one for your building — the stair calculator lists the common limits.
Outdoor stairs, fire escapes?
The same stairs, any width: set the height, the width and the build, and add the platform as a box.
