Zahner engineering and craft can be seen in cities around the globe. In the 1990s, the company began working in Hong Kong and the Middle East, on projects such as Kowloon Station, Tsing Yi Station, and the Ministry of Interior in Saudi Arabia. Since then, Zahner has worked in nearly every international market for architecture. In the 21st century, Zahner began exporting its technology for complex form design and manufacturing. These advanced components are manufactured in the United States, and assembled onsite for projects around the world.

Internationally, Zahner fabricates glass and metal for art, sculpture, and architecture. The firm provides not only custom fabrication and installation, but also a wide range of engineering and design services for custom projects in every aesthetic. See examples of international projects below.
