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.

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).

Back in June, I posted a picture of some induction heating process, for the new American Airlines headquarters in Fort Worth, Texas. In addition to the 16" square, we produced another set of 

The 1.7 million-square-foot complex, dubbed the “Trinity complex,” consists of constructing four seven-story buildings. It will cost at least $300 million to build and will house over 6,500 employees. There are 10 tower cranes on the project and there will be more than 1,000 construction workers on-site during the peak. It is scheduled to open during the second half of 2019.  These are the type of bends that ONLY Albina can do!

We recently spiral rolled 1/2" and 1" plate for a custom spiral staircase in a multi-million dollar luxury home on Green Street in San Francisco, California. We provided the rolled plate for the staircase and then flat plane rolled the plate for the landings. The tightest radius was a 29.75” center line radius.
