Curved Feather-Inspired Roof at Montana State University Campus
Curved Feather-Inspired Roof at Montana State University Campus

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

"Daunting Curves Ahead"- Article in O & M Metal Fabricator

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.

Thanks to Viva Railings LLC (Photo credit & Glass/Railing Fabricator) we have received some final installation pictures of the circular staircase at the "Trinity Complex", home to 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.

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

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).

Albina Co., Inc. Recognized at "The Spheres" IDEAS2 Presidential Award  Ceremony
Albina Co., Inc. Recognized at "The Spheres" IDEAS2 Presidential Award Ceremony

"The Spheres" in Seattle, Washington have been all the buzz lately! "The Spheres" were featured in the May 2019 Edition of Modern Steel Magazine as the buildings were awarded the AISC's IDEAS2 Presidential Award for Excellence in Fabrication!  Just this last week, our VP of Sales, Brad Lund, was able to attend the award presentation ceremony at "The Spheres" in Seattle and we were awarded a plaque to display in our office. See below for some AMAZING pictures!


Albina Co., Inc. was the steel bender/roller for the Curved Steel Bio-Sphere buildings in Seattle, WA. Albina bent 750,000# and 1,050 pieces rectangular tube steel bent the easy way and a portion bent off-axis. Almost 8 miles of welding work and grinding was avoided because of Albina’s ability to bend a portion of the project. Almost NO correction was needed during fabrication or erection as the bends fit to the fixtures within 1/32nd of an inch! Albina Co., Inc. also bent the handrails and spiral staircase for the interior of the buildings.

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 

steel spiral stringers for custom spiral staircase at new American Airlines Headquarters in Fort Worth, Texas

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!

Steel Spiral Staircase at the Ritz Carlton in Sunny Isles, Florida
Albina worked on a custom spiral staircase for the Ritz Carlton in Sunny Isles, Florida. This high profile spiral staircase was for a great customer out of Florida. When a top of the line luxury hotel needed top of the line bending, Albina was contracted. Yes! We shipped from Oregon to Florida to service the needs of our customer! Albina bent TS 16" X 4" X .500" WALL A500 GR B down to a 12’ inside radius (for the stringers and the landings). All bends were to AESS standards.
