Giant Arc Roof
System description 
The Giant ARC roof is a tower-based structure, constructed from 3 to 5 arches. Straight truss sections, combined with bottom hinges and topside spreader plates, provide the arch needed over the complete span. Two steel wires per span absorb horizontal forces caused by the loading. The arches are connected to either a standard ST or CT tower.
