Spiral Stringers Help Create Stunning Staircase at Altar’d State at The Forum Shops at Caesar’s Palace

Albina Co., Inc. recently rolled 16 pieces of 5/8″ plate A36 to as tight as a 162″ radius. Six pieces of plate were used as the inside stringers of a beautiful spiral staircase at Altar’d State at the Forum Shops at Caesar’s Palace. Six pieces of plate were used as the outside stringers of the staircase, and four pieces were used on the landings. We bent the stringers, trimmed rectangular treat cut outs, trimmed to length, match paired plates, tacked them together and match drilled all holes. We bolt matched the plates together with a 6 bolts, (2) on the end, (2) in the middle, and (2) on the other end.

We also bent 2½” X 2½” X ¼” ANGLE A36 to help create the spiral staircase. Materials included:

1 piece leg in to a 25” inside radius.  Albina to bend 180° minimum.

1 piece leg out to a 162” inside radius.  Albina to bend 70” minimum arc.

1 piece leg out to a 30” inside radius.  Albina to bend 36” minimum arc.

1 piece leg out to a 19” inside radius.  Albina to bend 80” minimum arc.

1 piece leg in to a 38” inside radius.  Albina to bend 180° minimum.

Lastly, we bent one piece of Flat Bar 5/8″ x 12″ A36 UM Plate leg in to a 38” inside radius and 180° minimum.

Spiral Staircases at the Newly Renovated Space Needle

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. 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).

Custom 12″ x 8″ HSS Spiral Stringer for Spiral Staircase in Utah

We recently spiral bent tube steel 12″ X 8″ X .625″ WALL A500 GR B Spiral the Easy way to a 173” radius for a customer spiral staircase located in Utah. Square and rectangular tubing is also known as HSS (hollow structural steel). Albina has the ability to bend both square and rectangular tubing. For rectangular tubing we can bend both the easy way (against the weak axis) and the hard way (against the strong axis). We can even provide Multi-Plane bending where we are bending both the easy way AND the hard way. Albina is a unique shop in that we can bend very small square materials such as TS ½” x ½” x .049” wall all of the way up to very large materials such as TS 20” x 12” x .625” wall, which happens to be the largest size that mills produce. Albina actually has a larger capacity than TS 20” x 12” x .625” wall, which means we can bend materials larger then what the mills produce!
