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.

Spiral Stringers Help Create Stunning Staircase at Altar’d State at The Forum Shops at Caesar’s Palace

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.

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!

Steel Spiral Staircase for the Moab Hoodoo Hotel- Curio Collection by Hilton

Albina recently completed some very complex spiral bends for a Spiral Staircase which will be installed at the new Moab Hoodoo Hotel, Curio Collection by Hilton in Moab, Utah. The 117-guestroom hotel will offer an upscale lodging option to travelers heading to the Moab desert community. The hotel will be surrounded by large sandstone monoliths that feature balanced stones, known as hoodoos.

Materials bent for the spiral staircase consisted of:
4″ X 4″ X ¼” ANGLE A36
2 pcs bent leg out to a 7′ 4″ inside radius
2 pcs bent leg in to a 13′ 0″ outside radius
C15 X 33.9# A36
2 pcs spiral bent to a 7′ 4″ outside plan radius.
2 pcs spiral bent to a 13′ 0″ inside plan radius.
1 pc bent in a single plane to a 7′ 4″ outside radius
1 pc bent in a single plane to a 13′ 0″ inside radius

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).
