National September 11 Memorial Museum Pavilion
The National September 11 Memorial Museum resides in the space between where the Twin Towers once stood in New York City. Designed by Snøhetta with Handel, Zahner manufactured the custom facade skin for the building. The architects worked with Zahner engineers and designers in the Design Assist team to develop the facade system. Zahner unitized the metal systems in Kansas City and then shipped everything to the job site for installation.
911 Memorial Overland Park
The 911 Memorial at Overland Park, installed at the entrance to the city's Fire Training Center, reminds first responders of the ultimate sacrifice their service may demand. The memorial was designed by SFS Architecture and includes artifacts and custom-fabricated bronze and steel artworks provided by Zahner.A 14-foot, 2.5 ton steel beam from ground zero stands at the memorial's center. Four bronze panels to beam's West tell the story of the four downed flights, and a bronze memorial listing the names of those who perished on September 11th sits to the East. A weeping wall fountain, representing survivors, stands to the North while granite tiles pulled from the World Trade Center after the attacks pave the South entrance.The memorial's three-fold mission is to remember the victims, educate visitors, and honor the heroism by those who served on September 11th, 2001.
Developing the 911 Museum Metal Facade
The panels were tested for wind loads and water permeability at a special facility. The panelization method used for the project required welding studs to the reverse of each panel. Zahner-trained fabricators welded the hardware at ideal penetration so that the stud-welds wouldn't show on the face of the metal panels.
The surface of the metal shell alternates between GB-60 polish and a No. 4 polish on stainless steel. The No. 4 polish has greater reflectivity along a linear grain, while the GB-60 surface scatters light for a more diffused look. This alternation repeats itself as a motif in not only the stainless steel facade, but also across the fenestration surface.
