Spiral Staircase for “The Hopservatory” at Worthy Brewing in Bend, Oregon

Albina Co., Inc. recently completed 14,000 lbs. of bent steel to create a beautiful spiral staircase at Worthy Brewing in Bend, OR. Bent steel materials for the project included:

MC18 X 42.7# A36 spiral bent lengths with flanges in and lengths with flanges out were bent down to a 9 ft plan view radius! Landing pieces were also spiral bent down to a 9’ 8” radius.

C15 X 33.9# A36 for the inside landings were spiral bent down to a 8’ 9” outside radius (plan view).

Bend, Oregon is located on the eastern edge of the Cascade Mountain Range along the Deschutes River and is a popular tourist town known best for the many outdoor activities offered and world famous micro-brews. Worthy Brewing Co. broke ground on Feb. 24, 2012 off U.S. Highway 20 on Bend’s east side — it’s Bend’s 1st east side brewery – and with a beer garden, hop garden, and Hopservatory. The spiral staircase winds up to The Dome at the top of the rotating Hopservatory where visitors can view the cosmic skies through an OGS 16” RC Reflector telescope.

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.

Induction Bending of Rectangular Tube Steel for New Additions at Olympic Towne Center in Gig Harbor, Washington

Albina is working on bending rectangular hallow structural steel for the Olympic Towne Center project in West Gig Harbor, Washington. The Olympic Towne Center development will boast 186,291 square feet of retail space and will anchored by a 65,000 square foot grocery store. This project requires Albina to bend some TS 12″ X 3″ X .375″ WALL A500 GR B rectangular tubing. Part of the project consists of spiral bent stair stringers, induction bent, down to an 6 foot plan view radius! This is a very tight radius for spiral bending HSS members. We are induction bending this material with our in-house designed induction bending method which will result in the highest quality spiral bends seen in the industry. We are also providing bends for the stair case landings. These bends are also down to a 6 foot radius and will all be provided to AESS quality standards.

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.

Spiral Steel Staircase at Brickell Academy in Virginia Beach, VA.

Albina recently completed the spiral bending of 24 pieces of Tube Steel 14″ X 4″ X .500″ WALL A500 GR B the easy way and 10 pieces of Tube Steel 12″ X 3″ X .375″ WALL A500 GR B
the easy way for a gorgeous spiral steel staircase at Brickell Academy in Virginia Beach, VA. All of the material for the curved staircase and landing was architecturally exposed structural steel.

Installation of Spiral Staircase at Orange Coast Memorial Hospital

Orange Coast Memorial Medical Center is the only nonprofit hospital in Fountain Valley, CA. Albina recently spiral bent and flat bent Tube Steel 16″ X 8″ X .500″ WALL A500 GR B to 13’ 6” and 18’ 10” plan view radii the easy way to form the spiral stringers for the staircase. See the installation pictures below. Finished install pictures coming soon!

Extremely Tight Tube Steel Spiral Stringers for Lakeside Campus Building Staircase

Enjoy the latest install pictures of the 20” x 8” x .625” wall tube steel which provides the base supports for a heavy weight bearing spiral staircase at the Lakeside Campus in Richardson, Texas. The tube steel was spiral bent the easy way using our induction heat source and increment bend method. The tube steel was bent down to a 7’ 7” center line (plan view) radius and all bends were to AESS standards. Albina also bent tube steel 20” x 12” x .625” wall for a different section of the spiral staircase. The 20″ x 12″ material was bent down to a 13’ 9” center line (plan view) radius and all bends were to AESS standards.The specifications to bend to a center line radius this tight is almost unheard of, but Albina was able to do it to perfection!

Tube Steel Spiral Stringers Provide Support for Heavy Weight Bearing Spiral Staircase

Albina recently bent tube steel 20” x 8” x .625” wall which will provide the base supports for a heavy weight bearing spiral staircase.  The tube steel was spiral bent the easy way using our induction heat source and increment bend method. The tube steel was bent down to a 7’ 7” center line (plan view) radius and all bends were to AESS standards.

Albina also bent tube steel 20” x 12” x .625” wall for a different section of the spiral staircase.  The tube steel was spiral bent the easy way also using our induction heat source and increment bend method.  The 20″ x 12″ material was bent down to a 13’ 9” center line (plan view) radius and all bends were to AESS standards.

The specifications to bend to a center line radius this tight is almost unheard of!  Albina was able to bend per the customers specifications and provide an exceptional quality product!

Curved Steel Spiral Staircase at Tommy Bahama Waikiki, HI.

Albina recently bent very large HSS (Hallow Structural Steel) rectangular tubing 16″ X 4″ X .500″ WALL A500 GR B for an elliptical staircase at the Tommy Bahama Restaurant & Bar at The Shops at Mauna Lani in Waikiki, Hawaii.

Upon extensive review of the plans submitted to Albina for production, it was determined that some radius changes were required. Many of the original radii required were actually deemed “too tight” to bend. Original plans called for bends that were as tight as a 3’-8” Centerline Radius. To remedy this problem, Albina was able to provide suggestions and recommendations regarding the radii that we were able to successfully bend while maintaining a high level of AESS (architecturally exposed structural steel) quality.

This was a unique project because the stringers, as detailed, included numerous different radii. Many stringers are designed with a single radius or just a few radii. This staircase was originally designed with such complexity that it would have been fabricated from 38 individually bent members. Albina’s suggestion to decrease the actual number of parts and instead “blend” some parts together helped simplify the bending process, and reduced the total number of full-penetration weld splices that customer would need to perform during fabrication. After much discussion, the staircase was redesigned, resulting in only 24 individual members (a 37% decrease in the number of bent parts and full penetration weld joints). These changes resulted in a quicker lead-time and a labor cost savings.

After receiving the elliptical bends from Albina, the customer commented, “Albina worked with us on time frames and cost issues. Albina must roll these pieces perfectly or we can’t even attempt to get a finish product on this end. We are counting on these things being correct…period. Albina is not afraid to take the risk of rolling a radius that hasn’t been done before. I appreciate the consistent and un-prodded reports on job status and progression.”
