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!

Spiral Rolled Plate for Spiral Staircase in Multi-Million Dollar Luxury Home on Green Street in San Francisco, CA.

We recently spiral rolled 1/2″ and 1″ plate for a custom spiral staircase in a multi-million dollar luxury home on Green Street in San Francisco, California.
We provided the rolled plate for the staircase and then flat plane rolled the plate for the landings. The tightest radius was a 29.75” center line radius.

Curved Steel Spiral Staircase for the New American Airlines Headquarters in Fort Worth, Texas

Albina recently used our induction heating process to spiral bend Tube Steel 16″ X 16″ X .625″ WALL A500 GR B bent down to a an 18 foot radius for the 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. Including the 16″ square, we have produced another set of spirals and have one in the queue. The one in the queue is Tube Steel 14″ x 6″ x .625″ wall REALLY tight, exposed and bent to a 5′-6″ radius on a 45° pitch. We already made a mock up for the job and all parties loved it. These are the type of bends that ONLY Albina can do! This is a really amazing project! Stay tuned for more pictures.

Curved Steel Spiral Staircase at the Capitol Visitors Center in Washington, D.C.

On a recent trip to Washington DC, we had the pleasure of touring the Capitol Building and we were able to capture some pictures of The Capital Visitors Center spiral staircase we bent years ago. The project consisted of flat and spiral bending of angle, channel, flat bar, solid square, wide flange (up to W18 x 76#) and square tubing (up to 10″ x 10″ x .500″ wall spiral bent).

Steel Bending Contract at Carnegie Mellon University- Distance is Not a Deterrent!

Never hesitate to contact Albina for any of your steel bending needs. We are your “local” steel bending company no matter where you are located!

Albina was recently awarded a steel bending contract for Carnegie Mellon University in Pittsburgh, PA. That is 2,566 miles across the United States! Our customer wanted the steel to be bent correctly, the first time, to high AESS quality standards, so they chose to contract with Albina.

For this project, Albina will be performing some very difficult spiral bending of TS 20″ X 8″ X .500″ WALL A500 GR B material. There are a total of 12 spiral bent sections and 6 sections that are bent flat (the easy-way).

Our customer couldn’t afford to make the mistake of using another bending company. They wanted to come to Albina because we have the most experience in the nation with large HSS spiral bending to the highest quality standards.

Steel Spiral Staircase at University of Nebraska Business Administration Building

Albina rolled the following materials to create a beautiful multi-level steel spiral staircase at the University of Nebraska Business Administration Building. A spiral, circular or helical bend occurs in a plan view with rise in elevation. Steel spiral staircases are architecturally and visually appealing, functional and an effective use of space.
