A staircase is the one part of a building you touch with every step. We build it as if that mattered.
Six models, each made to measure
Choose a model and turn it. Sides, treads and finish change from project to project. The mechanism does not.
A single steel spine under a straight flight. Each tread floats off it.

Questions we hear often
What kinds of steel staircases do you make?
Six signature models: a straight flight between laser-cut sides, a spiral on a central column, a straight flight on a central spine with cantilevered treads, an exterior switchback with a landing, treads set into a wall, and a helical stair on a curved stringer. We also build industrial stairs and walkways, and L-shaped stairs with a landing.
Can you work from our drawings?
Yes. Send a plan, a 3D model or a sketch (DWG, DXF, IFC, PDF or a hand drawing). We draw the stair, check it, and come back with shop drawings and a price.
Which tread materials and railings are available?
Treads in steel plate, timber or steel grating. Railings with vertical balusters, horizontal rods or cables, or glass. You can try each combination in the 3D configurator.
What finishes do you offer?
Paint, powder coating or hot-dip galvanising, depending on whether the stair is indoors, outdoors or industrial.
Do you install the staircase?
Yes. We deliver to site and fit the stair with our own crew.
Where are the stairs made, and do you deliver abroad?
In our own workshop in Sofia, Bulgaria, as part of BarDI Group. We deliver to France, Germany and across Europe.
Which standards do you build to?
Fabrication to EN 1090-2, with welding and quality control in our own workshop.
How much does a custom steel staircase cost?
It depends on the model, dimensions, tread material, railing and finish. Use the configurator or send us your details, and we come back with shop drawings and a price.
Is the 3D configurator a binding design?
No. It is an indicative visualisation. We confirm every dimension from your drawings or after a site check.
