“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.

Install Progress Picture of Curved Steel Spiral Staircase for the New American Airlines Headquarters in Fort Worth, Texas

Back in June, I posted a picture of some 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, for the new American Airlines headquarters in Fort Worth, Texas. In addition to the 16″ square, we produced another set of spirals consisting of Tube Steel 14″ x 6″ x .625″ wall REALLY tight, exposed and bent to a 5′-6″ radius on a 45° pitch. Below is a progress picture of the installation of these spiral stringers.

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. 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. We spiral and flat bent TS 20″ X 12″ X .625″ WALL A500 GR B the easy way down to a 56 ft radius.

Curved Steel Spiral Stair Stringers at Suffolk County Community College

Suffolk County Community College (SCCC), recently opened its new $30 million, 75,000 square foot Learning Resource Center (LRC) and library on the Michael J. Grant Campus in Brentwood, Long Island, New York. Albina Co., Inc. bent the steel spiral stringers for the project. The steel spiral stringers consisted of spiral bent tube steel 20″ X 4″ X .500″ WALL A500 GR B the easy way to a 14 ft. plan view radius. We also bent the landings to a similar radius. We also spiral bent tube steel 14″ X 10″ X .500″ WALL A500 GR B the easy way to a 19 ft. plan view radius and the landings also to a similar radius.

Steel Spiral Staircase for Goodwin Proctor Law Offices in California

Albina Co., Inc. recently completed bending spiral stringers of tube steel 10” x 6” x .625” wall all spiral bent the easy way down to a 7’ 4” inside radius. The stingers were bent for a Goodwin Proctor Law Office located in California. Albina Co., Inc. is the #1 steel stringer bender in the nation because Albina doesn’t split HSS prior to bending and then weld the sections back together to meet your needs, our HSS members are bent as HSS members. Albina doesn’t fill your HSS with other structural members. We are able to bend HSS members without adding extra material and weight and are still able to meet or exceed your quality requirements. Albina will bend your HSS stringers out of HSS material; we don’t make “built up stringers” out of plate.

Steel Spiral Staircase at the John J. Hemmingson Center Gonzaga University

Albina Co., Inc. bent 40,000 lbs. of various sizes of tube steel for the spiral staircases at the John J. Hemmingson Center at Gonzaga University Spokane, WA. Materials consisted of Tube Steel 16″ X 8″ X .500″ WALL A500 GR B rolled the easy way down to a 22 ft radius. These lengths of material were spiral bent using our induction heating process to AESS standards. We also bent Tube Steel 12″ X 6″ X .250″ WALL A500 GR B rolled the hard way down to a 19 ft radius. The John J. Hemmingson Center was completed in 2015 and serves as a meeting place for students, staff and visitors the University. We visited the campus shortly after it opened and my son will tell you that the highlight for him was the cafe where you can make your own milkshakes! He was sold from then on out and hopes to attend Gonzago University himself one day!

Spiral Stair Stringers for an Office Complex in San Francisco, California

We provide both functional and fancy solutions when supplying spiral stringers for spiral, circular and helical staircases to our customers. We specialize in architectural exposure quality spiraling of tube steel, channel, plate and pipe to amazingly tight radii and steep pitches. We work on both commercial and residential applications. We recently spiral bent Tube steel 10″ X 6″ X .625″ WALL A500 GR B the easy way down to a very tight 7 ft inside radius for an office complex in San Francisco, CA. All of the material was bent to AESS (Architecturally Exposed Structural Steel) standards. We are currently working on obtaining some amazing pictures of another project, the spiral staircase that we completed for the University of Gonzaga Student Union. I will post the pictures as soon as we received them so check back!
