This custom Duvinage spiral stair in 6’ diameter was added above a vintage Duvinage stair, augmenting the vertical access in this historic home. Featuring two sides of custom helixed grab rail and our 251 bar grating tread in steel designed to emulate the cast iron vintage stair on the lower level. An integrated straight run at the top of the stair leads to a roof deck. Shown in primer finish prior to field finishing. Location: Alexandria, Virginia.
