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.

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!

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.

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!

New Spiral Staircase at Golden West College Huntington Beach, CA.

Albina is happy to be teamed up with a very loyal fabricator on the Golden West College Project located in Huntington Beach, CA. Construction of a new 51,969 square foot building at the center of campus will house all student services. A new spiral staircase with landings was required for the new building and the California fabricator new the best choice for this project was Albina.

This project required Tube Steel 16″ X 4″ X .500″ WALL A500 GR B material to be spiral bent for the stringers and also bent flat (the easy way) for the landing supports. The spiral staircase also required some smaller HSS square tubing for stringers and landings out of Tube Steel 6″ X 6″ X .625″ WALL A500 GR B. Everything on this project was bent to AESS standards.
