“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.

Final Install Pictures of Curved Steel Circular Staircase for the New American Airlines Headquarters in Fort Worth, Texas

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

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.

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. Click here for images of the spiral staircase and the newly renovated hotel.

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!

Curved Steel for the Fort Worth Multi-Purpose Arena in Fort Worth, Texas

We just finished a project for a new customer out of Texas. Albina Co., Inc. provided 40,000# of bent steel for the Fort Worth Multi-Purpose Arena project in Fort Worth, Texas which broke ground on April 18th. Albina provided 28 pieces of spiral bent Tube Steel 8″ X 4″ X .500″ WALL A500 GR B the easy way to AESS (Architecturally Exposed Structural Steel) standards. The tightest section was bent to a 17 foot radius. The Fort Worth Multipurpose Arena will be a 14,000-seat, multipurpose venue owned by the City of Fort Worth. The state-of-the-art arena, scheduled to open in November 2019, will host concerts, sporting events and family entertainment, and will be the new home to Fort Worth Stock Show Rodeo performances.

Curved Steel: Spiral Bending of Tube Steel for the Philadelphia Museum of Art

Believe it or not, but Albina ships our bent steel all over the US and Canada! In fact, we recently finished a project for the Philadelphia Museum of Art. Our bent steel shipped to our customer in Virginia to be fabricated and was then shipped to the job site in Pennsylvania.
