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 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.

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.

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.”
