Three major projects were recently completed in the United States in which stainless steel played an important part: a tower in Portland, Ore., and two skyscrapers in Chicago. ThyssenKrupp Nirosta (Krefeld) manufactured the material for the stainless steel elements, which were then processed by Cologne-based Christian Pohl GmbH and delivered to North America.
Both buildings in Chicago were designed by architectural firm Goettsch Partners. The “Blue Cross-Blue Shield Tower” project involved adding further stories to the existing building. Columns were clad with the material Nirosta 4301. Overall, about 22 tonnes of stainless steel were used for the 226-meter, 54-story office tower.
About 24 tonnes of linen-finish stainless steel were used to clad column elements in the 195-meter, 45-story building on North Wacker Drive in downtown Chicago.
The 81-meter residential tower in Portland, designed by the architects Zimmer Gunsul Frasca Partnership, features facade panels of stainless steel. Around 1800 square meters of the exterior is clad with Nirosta 4401 (finish: linen – design 25). ThyssenKrupp Nirosta supplied some 36 tonnes of this material.
ThyssenKrupp Nirosta is one of the world’s leading manufacturers of stainless flat products with a broad range of stainless steel grades, sizes, and finishes. The company has several sites in Germany and employs around 4200 people.
Christian Pohl GmbH is a Cologne-based company with activities in metal processing, sheet metal structures, and the production of metal facades. The international Pohl group employs around 500 people.
