Sheet Metal Magicians
Technologist Peter Hall publishes a story about A. Zahner Company for Metropolis Magazine.
”On a glaringly bright June afternoon in Kansas City, I find myself standing outside a factory building admiring the effects of the Missouri climate on panels of perforated copper. “When we were constructing this we had a severe ice storm in Kansas City,” says my tour guide, Paul Martin, a mechanical engineer who had helped design the panels. “After it melted away it had the most spectacular purples.” He points to the verdigris streaking in the cinnamon-colored surface. “The way water falls down copper…there’s no way to replicate it.”
This begins an eight-page story in Metropolis Magazine detailing how Zahner began its journal from a small-scale sheet metal factory into a company producing some of the most iconic architectural works in the United States — and the world at large.

Herzog & de Meuron developed the idea of a variably perforated screen exterior which would mirror the green foliage and forestry of the surrounding Golden Gate Park, San Francisco's central park. The architects worked with Zahner whose engineers and software specialists developed a system which would allow unique perforation and patterned dimples, variably sized and placed throughout the exterior. This included near 8000 unique facade panels — the collective whole which formed patterns of light as seen through trees. This was the first iteration of the Zahner Interpretive Relational Algorithmic Process, or the ZIRA Process.
