Video: Mercedes-Benz Stadium Releases Time-lapse of Roof Closing
Friday, July 28th, 2017
In the last 48 hours the roof has closed at Mercedes-Benz Stadium and it looks incredible!
More facts and figures about the roof’s mechanization:
The stadium roof may appear to rotate open but it’s an optical illusion, the roof opens by the movement of eight “petals” that slide open in a straight line.
Each of the moving petals cantilever approximately 200 feet inwards towards the center of the stadium and provide a roof covering when the petals are in the closed position.
The moveable petal structures are powered by eight mechanized “bogies” which drive the petals along an inner rail and are attached to the outer uplift rail by six roller mechanisms
In the closed position the petals lock together to form a water tight seal. Each petal structure is clad with air-inflated ETFE pillows.
ETFE is a highly durable, lightweight fabric that is translucent, allowing for a light filled stadium, even when moveable petals are in the closed position.
