The Hyatt Regency, located atop the Bethesda Metro station and minutes from downtown D.C., features an award winning staircase the newly reimagined lobby space. The Ernest Wiemann Top Job Contest is a peer-judged competition created to honor outstanding work. The staircase, fabricated by Emerald Ironworks, took home a silver Ernest Wiemann Top Job Contest Award in the "Commercial-Stairs Complete" category. 

The interior stringer of this "floating" staircase has five different radii. The stringers had to be clad in wood and the steps in Italian marble. Most impressive, ot steel stringers installed to within 1/32" tolerances. Materials bent for the staircase included:

TS 18" X 6" X .625" WALL A500 GR B

               1 pc spiral bent the easy way to a 143 ft plan view radius

               1 pc spiral bent the easy way to a 14 ft plan view radius

               1 pc bent the easy way to a 17 ft radius

TS 16" X 4" X .625" WALL A500 GR B

               1 pc spiral bent the easy way to an 18 ft plan view radius

               1 pc bent the easy way to a 21 ft radius

               1 pc bent the easy way to an 18 ft radius

TS 10" X 6" X .500" WALL A500 GR B

               1 pc bent the easy way to a 28 ft radius

               1 pc bent the easy way to a 19 ft radius

TS 20" X 8" X .625" WALL A500 GR B

               2 pcs bent the hard way to an 18 ft radius

               1 pc bent the hard way to a 15 ft radius

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.

Albina Co., Inc., was lucky enough to be the bender/roller for a beautiful spiral staircase that graces the lobby of one of the major tech companies headquartered in San Jose, California. Albina bent the following materials for the project:

Tube Steel 3" X 3" X .375" WALL A500 GR B
Channel C15 X 40# A572-50
3/8" THICK X 24" WIDE CORTEN PLATE
¼" THICK X 77¾" WIDE CORTEN PLATE
¼" THICK X 29½" WIDE CORTEN PLATE

The Inside stringer for the staircase was rolled to a 26’-11” radius and the outside stringer was rolled to a 32’-3” radius.
