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.

All misc. stair parts bent by Albina to various configurations.

Materials: PL 1" THICK X 14" WIDE A572-65
All Ribbon Helixes bent by Albina to a 3’-0” plan view radius (spiral rolled the easy-way).

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.

Albina Co., Inc., was lucky enough to be the bender/roller for a beautiful spiral staircase that graces the lobby of one of the major tech companies headquartered in San Jose, California. Albina bent the following materials for the project:

Tube Steel 3" X 3" X .375" WALL A500 GR B
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.

One of Southern California's iconic, flagship waterfront restaurant sites - 1360 North Harbor Drive along the North Embarcadero, is getting a facelift! 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.

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.

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!

Albina recently spiral bent several stringers for a state of the art spiral staircase for the Buddy Holly Hall of Performing Arts and Sciences in Lubbock, Texas. The Lubbock Entertainment and Performing Arts Association (LEPAA) has had the vision for this building since 2013 and broke ground just over a year ago in April 2017. The dance center will contain the entire operation of Ballet Lubbock, including six dance studios, parent and community space, production areas and administrative offices and expected to be complete in early 2020. Check out this website for artist renderings of the building and interior features such as the spiral staircase we bent consisting of: TS 16" X 8" X .625" WALL A500 GR C 16 pcs: Spiral bend the easy way Bent down to a 7 ft plan view radius. TS 10" X 6" X .625" WALL A500 GR C 10 pcs: Spiral bend the hard way Bend down to a 14’ 11” plan view radius.
