The Guggenheim Canopy, designed by Frank Gehry Partners, is a Zahner-manufactured installation which was on view at the Solomon R. Guggenheim Museum in New York City beginning in 2001. The artwork was erected for a Frank Gehry retrospective at the Museum in May-August, 2001. In addition to providing the canopy, Zahner also manufactured a number of mirror-polish stainless steel tables for the rooftop cafe.
The canopy artwork was manufactured using a titanium skin and aluminum structure. The form was made using ZEPPS, the Zahner-patented technology for building sculptural forms. This system was used to build the aluminum structure. The titanium was then clad over the aluminum substrate using a custom flat seam system.
The titanium's luminescent coloring was made possible by a thick layer of oxide on the metal surface. There are two distinct overlapping forms, and each is colored using a unique color of titanium-cladding made by varying the oxide thicknesses. This oxide process is called interference-coating, and can be used to create a range of iridescent colors on stainless steels and titanium surfaces.
