Bill Zahner

Under his direction, A. Zahner Company evolved from a regional sheet metal contractor into an internationally recognized provider of architectural metal systems and building envelopes. The company’s work spans cultural, institutional, and commercial projects, often involving complex geometries and custom fabrication techniques developed in collaboration with architects, artists, and engineers. 

This approach is reflected in a range of collaborations with architects and artists working at the intersection of design, engineering, and fabrication.

Selected Collaborations and Projects

Throughout his tenure, Mr. Zahner worked closely with leading architects, designers, and artists on projects that required specialized metal fabrication and engineering. These collaborations typically involved early coordination between design intent and fabrication methodology, particularly for complex geometries and custom surface systems.

Selected collaborations include:

• Museum of Pop Culture (Seattle, Washington) — Designed by Frank Gehry Partners, this project involved the development and fabrication of highly expressive metal forms, requiring iterative coordination between design modeling and manufacturing processes.
• Gates Hall, Cornell University (Ithaca, New York) — Designed by Morphosis, the building incorporates a custom metal façade system that integrates performance requirements with a distinct geometric expression.
• Petersen Automotive Museum (Los Angeles, California) — Designed by Kohn Pedersen Fox (KPF), the project features a stainless steel ribbon façade system engineered to achieve both structural performance and visual continuity across a complex surface.
• De Young Museum (San Francisco, California) — Designed by Herzog & de Meuron, the project features perforated copper that mimics the filtering of light through trees. This required the development of a new technology, the patented Zahner Interpretive Relational Algorithmic Process (ZIRA), which later evolved into the ImageWall perforated panel system.
• Artwork by Jan Hendrix — Mr. Zahner has collaborated for several decades with artist Jan Hendrix on numerous sculptural and architectural works that translate detailed artistic patterns into fabricated metal systems, often requiring custom tooling and process development.

These projects reflect a broader pattern in the work of Mr. Zahner and the Zahner team: the integration of engineering, material science, and fabrication into the realization of architectural and artistic concepts.

Industry Contributions

Mr. Zahner has contributed to the advancement of architectural metals through both practice and research. He holds multiple patents related to metal systems and fabrication processes, and has served as an industry liaison for the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). 

In 2013, he was appointed to the U.S. Department of Commerce Manufacturing Council, where he advised on policies affecting American manufacturing. 

He was named an Honorary Member of the American Institute of Architects (AIA) in recognition of his contributions to the field. 

Publications

Mr. Zahner is the author of multiple books on architectural metals, including the Architectural Metals Series, which provides technical guidance on the selection, specification, and performance of metals in architecture and art.

His publications cover materials such as stainless steel, aluminum, copper alloys, zinc, and steel, and are used by architects, engineers, fabricators, and students as reference texts for material application and performance. 

Lectures and Speaking

Mr. Zahner has lectured widely on the role of metal in architecture, fabrication methodologies, and the integration of design and manufacturing. His presentations have been delivered at universities, industry conferences, and professional organizations including AIA chapters and engineering institutions.

Common themes in his talks include:

• The integration of structure and surface in contemporary architecture
• Advances in fabrication technologies and custom metal systems
• Collaboration between designers, engineers, and fabricators
• The evolving role of materials in architectural expression 

Professional and Civic Involvement

Mr. Zahner has served on several boards and advisory groups, including:

• Kansas City Art Institute Board of Trustees
• Nerman Museum of Contemporary Art Advisory Board
• University of Kansas School of Engineering

His work reflects an ongoing interest in the intersection of art, engineering, and manufacturing.
