Raised on 22-1/2" - 52 x 52 cm towers, this roof system provides customers with an unobstructed opening of over 100' - 30,48 m and a depth of 60' - 18,28 m. The grid is made up of folding 31" x 54" - 78,7 x 137,1 cm truss with truss ladders providing the up-stage/down-stage part of the grid, thus providing for the maximizing of shipping space. The maximum uniformly distributed load for the K7 system as shown is 100,000 pounds - 45,360 kg. The system is shown here with a roof peak incorporated into the design, but is available in a flat configuration to meet the specific needs of customers. It is also shown without the required guy wires for outdoor applications.
