On December 3, 2013 Spiral Stairs of America reached a triumphant milestone that few other businesses ever see - its 40th year of continuous operations. Initially regarded a small side business by the owner of a regional weld shop, the sales of spiral stairs began to climb almost as soon as they were introduced. Sensing a good opportunity, he spun the business (and kept ownership) off into a new company, christened "Spiral Stairs of America". A very grandiose name for a very small business in the relatively small town of Erie, PA.
Now, 40 years later, we have definitely grown into the name "Spiral Stairs of America" but with sales to Korea, Hong Kong, Singapore, Canada and elsewhere, maybe it's time to change our name! We have introduced new products and new designs steadily over the years and after waiting until we had the perfect design, we FINALLY introduced a kit stair worthy of our name. We also do a tremendous amount of business in monumental and curved stairs - wood and steel designs. And our newest product introduction, Rolling Library Ladders has been a run-away (no pun intended) success.

** NOTE TO SPECIFIER ** Our classic and ever stylish spiral stair adds an accent to any room. Whether you need the functionality that only a spiral can deliver, or you need the form that only a spiral can provide, we have the right stair for you. Sturdy, yet graceful, the spiral stair will be a focal point of any area. We see spirals used in both interior and exterior applications, for both residential and industrial/commercial uses. Our standard spiral design features square vertical balusters between the tread and handrail. We can customize these balusters, offering dozens of choices, styles, and profiles. Standard tread design is smooth steel (12 gauge) but we offer checker plate, bar grate, wood covers, and more. The basic handrail is 1.5 inches O.D. steel tube, but again, we offer a multitude of choices, including one piece wood handrails, brass top caps and molded steel handrails. Matching balcony or well railing to match the stairs is available also. If building codes apply in your situation, or if you have young ones and pets in the house, we build stars which comply with (and exceed in many cases) the standards of BOCA, CABO, IBC, IRC, and other national codes. Additionally, we offer enhancements to these codes which may be required from your local building departments, including: latching gates, ADA complaint rails, and semi-closed risers.

2.2 SPIRAL STAIRS WELDED UNIT

2.2.1 Style/Design: As indicated on Drawings.

** NOTE TO SPECIFIER ** Deco Spiral Staircase image Our DECO model - Multi-Line Rail System or Horizontal Railing System - 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 inches rails, or a 7-line DECO with our EXCLUSIVE flat-plate or cover stringer. The cover stringer is exactly that: a 12 inches high band of metal that covers the tread ends and adds additional sleekness to an already shapely stair.
