Circular and Monumental Stairs

Duvinage has been designing and fabricating fine circular and monumental stairs since 1895. Designed with architects in mind, our single and double stringer designs form to a perfect contour. Our steel treads receive marble, wood, carpet, terrazzo, tile, concrete, glass, and more. Custom curved railings in metal and wood are our specialty.

We provide full shop drawings and Professional Engineering calculations for your stair, letting you concentrate on the architectural beauty without the worry of structural concerns.

Duvinage stairs are in The White House, The Ritz Carlton, The National Gallery of Art, and fine homes across the country.
