Zahner serves the Middle East for art fabrication and architectural manufacturing. Zahner craftsmanship can be seen in several regions of the Persian Gulf, including Doha, Iraq, and Saudi Arabia. In the 1990s, Zahner worked on the Ministry of Interior in Riyadh, the company's first project in the Middle East. Since then, Zahner craftsmanship has been seen on a number projects in Western Asia.

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.
