Our DECO model spiral stair features multiple round tubes (lines) bent into a helix shape - all in horizontal lines below the handrail. This stair can be manufactured with 3, 4, 5, 6 or 7 lines - while 5 lines or 7 lines are most popular.
The DECO stair is a welded, one-piece spiral which arrives at your location ready to install. If there are limitations to getting the stair into the building, we can splice (cut horizontally) the stair into 2 or more pieces to aid in installation.
If building codes apply, you will need a 7-line DECO with 1 1/2" rails, or a 7-line DECO with our EXCLUSIVE flat-plate or cover stringer. The cover stringer is exactly that: a 12" high band of metal that covers the tread ends and adds additional sleekness to an already shapely stair.
For more than half a century, Spiral Stairs of America has meticulously handcrafted staircases for public, commercial, and residential clientele around the world.
