Albina Co. Inc. bent the spiral staircases at the newly renovated Space Needle in Seattle, Washington. The Space Needle's rotating glass floor, dubbed "The Loupe", is located just below the open-air observation deck and Albina Co., Inc. was the steel bender/roller for the custom spiral staircases connecting the two areas. The stair centilevers off concealed supports, so the staircase appears to float above the glass floor below thus creating a very unique experience for the visitors.
Albina Co., Inc. bent 1" thick x 13 ¼" wide A572 GR 50 to yield three 180" pieces and three 144" pieces of rolled plate and 1" thick x 10-13/16" wide A572 GR 50 to yield one 80" piece of rolled plate. We also bent tube steel 10" x 6" x .625" WALL A500 GR B to a 11’ 6” inside plan view radius (the easy way).
More detailed information on the project can be found in the May 2022 Issue of Modern Steel.
