Materials: Painted steel stairs
This monumental stair was inspired by horse racing: it features heavy guard rails like those that line a track, and panels like starting gates adorned with jockey numbers.
It rises four stories to a lookout with a 360 degree view. Each flight differs from each other in terms of height, width, or interface with the building. The staircase is painted steel with an offset brushed stainless steel handrail.
The engineer was concerned that the structure should be rigid, so he specified HSS 14 x 4 x 5/8” stringers, and top rails made from 3.5” XS pipe (.318” wall). With just those two elements, each linear foot of the staircase weighs over 160#. The staircase was fabricated in sections within our shop—some segments nearly reached our ceiling. One of the biggest challenges was adjusting the radii of the stringers in small increments to correctly fit into the existing walls of the site.
