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.

The Buddy Holly Hall of Performing Arts and Science in Lubbock, Texas is a 220,000 square foot state-of-the-art campus featuring two theaters, event space, a full-service bistro and a ballet academy under one roof. Albina bent various materials for the signature spiral staircase in the Christine DeVitt Lobby. See LINK IN OUR BIO to get a sneak peek inside!

Two major construction projects are just wrapping up at the University of Oregon and curved steel is at the forefront of both projects!
The Phil and Penny Knight Campus for Accelerating Scientific Impact Sky Bridge.
Albina Co., Inc. bent 22″ OD x 1″ Wall Carbon Steel Pipe to a 105 foot center-line radius for a signature sky bridge that spans Franklin Boulevard and serves as a connector between campus and other U of O research facilities. The $225 million, 160,000-square-foot first phase opened in the Spring of 2020. Click on the link in my BIO to take a virtual tour of the building.

“The Front Runner in Steel Bending. We Tower Above the Rest” We were thrilled to be an integral part of reconstructing Hayward Field at the University of Oregon. Hayward Field is the world-class home to @OregonTF.
Albina created the curved steel diaphragm used to support the roof structure and provided various bent materials to help construct the landmark tower at the northeast corner of the facility. Designers wanted to create a structure that was open and airy, allowing spectators to enjoy great views and natural daylight, in an intimate environment.
For the roof, we rolled 600 lengths, varying from 28’-0” to 75’-6” long, of 14" OD X .375" / .500 WALL A500-18 GRADE B&C. That is 1,500,000# lot weight (750 tons) of rolled steel, 32 inbound trucks and 90 outbound trucks. The 14” OD material was laid over the top of the plate that we bent for this project. We bent 300 lengths, varying from 3’-0” to 37’-0” long, of PLATE 1½" THICK X 16¾" WIDE A572 GR. 50 and PLATE 1½" THICK X 10" WIDE A572 GR. 50.
In addition to the iconic roof, the tower at Hayward (187 feet tall) creates a community landmark honoring the first 100 years of track and field at Oregon. We rolled 400 lengths, varying from 20’-0” to 60’-0” long, of Tube Steel 8" X 4" X .500" WALL A500 GR B, 8-5/8" OD X .625" WALL A500C WHEELED, 8-5/8" OD X .375" WALL A500C WHEELED, 8-5/8" OD X .250" WALL A500C WHEELED, and Flat Bar 3/8" X 4½" A36. That is 330,000# lot weight (165 tons) of rolled steel, 10 inbound trucks and 16 outbound trucks! Photo Credit: Oregon Track & Field.
Our work was extremely precise, and we had zero rejected parts by the fabricator, Fought & Co., Inc. When measuring the work points during fabrication, they never once had to heat up or adjust the bending. To make the erection process go smoothly, we marked every 3-4 feet on the centerline back of the pipe to assist in the layout process for the diagrid “fish-mouth” stubs, and up-stands for the roofing system.
The Awards just keep on coming! The National Steel Bridge Alliance has awarded the Williams Creek Shoup Bridge in Salem, Idaho a Merit Award in the Medium Span bridges category. Albina was happy to be a part of the project and provided 145,000# of bent structural steel and HSS including:
W18 X 234# A992 4 lengths x 100 ft- bent the easy way to a 179 ft radius 2 lengths x 75 ft- bent the easy way to a 179 ft radius
TS 8" X 8" X .375" WALL A500 GR B 8 lengths x 53 ft: bent to a 304 ft radius.

The Barbara Walker Crossing Footbridge, along the Wildwood Trail in Portland, Oregon, is the official winner of two prestigious CODA awards, organized by CODAworx, an online global design platform which celebrates the worlds best in public art. The footbridge won a People's Choice Award as voted on by the public, as well as an award in the transportation category. . Click to watch the YouTube Video featuring the bridge. The bridge, designed by local artist, Ed Carpenter, is 178’ long measured at the center of its curving deck. Its basic structure is a tri-chord truss of rusting and painted steel. Carpenter’s design evokes imagery of the sword ferns and vine maples lining the entire length of the Wildwood Trail. This project is a collaborative effort of the Portland Parks Foundation in partnership with Portland Parks & Recreation (PP&R), the Portland Bureau of Transportation (PBOT), and Metro. Albina Co., Inc. bent 3½" SCH80 A847 and 5" SCH40 A847 all rolled to various radii, as well as 1" SCH40 A53B, 1½" SCH40 A53B, 1½" SCH80 A53B all rolled to various radii.
