Polished Finished Products

Don’t interrupt your sleek design with glimpses of the unfinished center column. Our continuous sleeves have the dual function of connecting the steps to the center column while completely concealing it.


A Touch of Warmth

You can accent this bold design with some traditional wooden accents. With the addition of solid wood steps and handrail, you can a little bit of classic home design top your spiral stair.


Safety is a Priority

Even our most unique stairs include safety features to ensure the comfort of you and your guests. The center spindles and code compliant risers close off any large gaps in your stair’s frame.
