“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.

Curved Steel at our Nation’s Schools & Universities

Boy how the tide has turned! No longer do I hear, “I don’t want to go to school today!” Instead I hear, “I can’t wait until we get to go back to school!” Kids across the country are gaining a new appreciation for how important it is to physically be able to enter their school buildings to learn. We have been very fortunate to be involved in a number of projects at schools across the nation including custom spiral and circular staircases, curved steel signs, curved steel artwork, curved steel canopies, and more!

Spiral Staircases at the Newly Renovated Space Needle

Albina Co. Inc. bent the spiral staircases at the newly renovated Space Needle in Seattle, Washington. The Space Needle’s rotating glass floor, dubbed “The Loupe”, is located just below the open-air observation deck and Albina Co., Inc. was the steel bender/roller for the custom spiral staircases connecting the two areas. Albina Co., Inc. bent 1″ thick x 13 ¼” wide A572 GR 50 to yield three 180″ pieces and three 144″ pieces of rolled plate and 1″ thick x 10-13/16″ wide A572 GR 50 to yield one 80″ piece of rolled plate. We also bent tube steel 10″ x 6″ x .625″ WALL A500 GR B to a 11’ 6” inside plan view radius (the easy way).

VERY TIGHT Spiral Stringer!

The Albina Co., Inc. team recently spiraled a true HSS stair stringer to a very tight configuration for a spiral staircase project in Washington. The project consisted of using an induction heat source, on our custom made bending equipment, to spiral bend tube steel 16″ X 12″ X .625″ WALL A500 GR B the easy way to a 77” Center Line Radius. VERY TIGHT and VERY IMPRESSIVE! Great work team!

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!

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.
