We had the pleasure of staying at The Arizona Biltmore (A Waldorf Astoria Resort) recently and got to experience the new Paradise Waterslides firsthand. Equally as impressive as the slides themselves is the spiral staircase used to acend to the top of the slides. Materials Albina bent for this project included tube steel, various sizes and widths of pipe and round tube as well as several pieces of angel and channel. Next Level Steel was the fabricator on the project.

Albina recently rolled various material for the eagle feather-inspired roof at the American Indian Hall at Montana State University in Bozeman, Montana. ThinkOne Construction Management designed a barrel-vaulted, curved, standing beam roof in the shape and color of an eagle feather. Metal roofing was specified to ensure durability and to create a non-penetrating attachment point for solar panels. The project was featured on page 37 of the October/November Issue of Metal Architecture.

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. 

The facelift to 1360 North Harbor Drive along the North Embarcadero is complete! The Port of San Diego and The Brigantine, Inc. began construction in July 2018 to redevelop Portside Pier including introducing four new dining concepts and enhancing the panoramic views of San Diego Bay for daily visitors. Albina Co., Inc. provided 60,000 pounds of various bent materials for the unique curved roof structure as well as for a signature spiral staircase that leads from the dock to the second floor public walkway and viewing deck.

A recent issue of O & M Metal Fabricator Magazine, produced by NOMMA, features a case study written by Jeff Fogel with input from key members of the Albina Team, on the great spiraling feat it took to create the spectacular spiral staircase at the American Airlines Headquarters in Fort Worth, Texas.

We spiral bent Tube Steel 16″ X 16″ X .625″ WALL A500 GR B bent down to a an 18 foot radius, using our induction heating process to create the spiral stringers for the staircase. In addition to the 16″ square, we produced another set of spiral stringers consisting of Tube Steel 14″ x 6″ x .625″ wall REALLY tight, exposed and bent to a 5′-6″ radius on a 45° pitch. These are the type of bends that ONLY Albina can do! The 1.7 million-square-foot complex, dubbed the “Trinity complex,” consists of four seven-story buildings. It cost nearly $300 million to build and houses over 6,500 employees. There were 10 tower cranes on the project and more than 1,000 construction workers on-site during the peak of the project.

Channel C15 X 40# A572-50
3/8" THICK X 24" WIDE CORTEN PLATE
¼" THICK X 77¾" WIDE CORTEN PLATE
¼" THICK X 29½" WIDE CORTEN PLATE

The Inside stringer for the staircase was rolled to a 26’-11” radius and the outside stringer was rolled to a 32’-3” radius.

Albina Co., Inc. recently rolled several materials for a custom spiral staircase. Materials bent by Albina Co., Inc. include:
PL ¾" X 14" A36- spiral rolled to a 5’ 3” plan view radius and a 9’ 3” plan view radius.
PL ¾" x 4" A36- spiral rolled to a 5’ 3” plan view radius.
PL ¾" X 8" A36- spiral rolled to a 5’ 3” plan view radius.
1½" OD X .120" WALL HREW: Rolled to a 8’ 11” plan view radius.

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.
