Kansas City Star
Kansas City Star Production Facility
The production facility for the Kansas City Star includes a locally manufactured, custom-patinated copper, created by Zahner for the building’s facade. The new production facility for the Kansas City Star was designed and developed by The Austin Company, an engineering design firm specializing in large-scale industrial facilities.
Zahner developed a preweathered copper patination system for this building. An estimated 4155 pre-patina copper panels were installed on the building’s surface to create the 80,000 SF surface area. The building’s green surface is mottled and variegated, a patina designed to age the building’s copper surface by 200 years. The natural patina will continue to grow and change in appearance as it ages. The patina provides a layer of natural protection for the copper alloy.
Zahner has developed proprietary techniques to preweather copper and copper-alloyed sheets with deep, rich patinas not unlike those that formerly took several decades to develop naturally. Some of these techniques can develop the rich green and blue tones of cupric nitrate on the copper surface. Other techniques will develop browns, yellows, and oranges in various hues.
