Philadelphia Post Office

Philadelphia, Pennsylvania

The new Philadelphia Post Office has been recognized as its historic predecessor. Fabral Hefti-Rib exposed fastener wall panels in perforated, stainless steel canvas the exterior. The effect is modern and industrial. The panels provide superior durability and environmental advantages. Stainless steel adds solar-reflecting properties. And the material is completely recyclable, furthering the building’s sustainability.

Perforation, such as in this project, is ideal for acoustical considerations, to help minimize wind loading or purely for aesthetic effect. Stainless steel is very strong and extremely corrosion resistant, especially when exposed to the elements such as smog and car pollution in major metropolitan areas.
