Mahaffey introduced the Super Series to the North American market in 1981.  Since then, it has been used thousands of times for every imaginable application. The hollow, aluminum box beam uses an ingenious groove in each of the four corners.  A fabric welt, called keder, slides into the grooves in the box beam.  The result is a lightweight fabric structure that can be rapidly installed and withstand severe weather conditions.
 
The Super Series is modular with 16.4 ft, or 5m, bays added one to another for theoretically unlimited lengths.

Cross section dimensions for Clear Span Super Series structures ranging
from 33' in width to 164' in width with unlimited lengths.
