Description

The Expo Boulevard is a 1km long channel which is designed to connect the entrances of major pavilions of the 2010 Shanghai World Expo Park and also the elevated pedestrian walkway. Consisting of 2 floors underground and 2 floors above the ground the Boulevard is a large-scale, multi-functional combination of transportation, commercial activities, catering, entertainment and exhibition services. The six 40m high horn-shaped structures
of the "Sunny Valleys" divert sunlight into underground levels of the Expo Boulevard and collect rainwater for use after recycling. In these six valleys there are about 10000 joints and every joint has a different angle and position. So the construction has to be very precise.
Saint Gobain Performance Plastics supplied more than 100.000m2 PTFE Architectural Membrane for the roofing tensile membrane structure covering the whole Boulevard to create an innovative, spectacular spatial visual effect. Saint-Gobain Performance Plastics is supplying FEP and PFA for welding PTFE fabric membranes and ETFE for film membrane construction.
It’s scheduled to be completed by the end of 2009. The Expo Boulevard project is not only a landmark project in the Expo district, but will also be a city landscape architecture of Shanghai in the future.
