This 54-riser custom Duvinage 220 spiral stair in 6’ diameter spans over 42', providing vertical access at this multi-residential complex. That’s tall, but not our tallest! With standout features that include custom helixed steel rail, solid steel balusters, checker plate steel treads with structural support legs and <4” spacing, and two platforms including a 90° rest platform. A fine example of The Boston’s uncompromising strength. Finished in hot-dip galvanizing. Location: Upstate New York.
