The ARC Roofs are available in a fixed-leg up to 10m wide and in a tower version from 12 to 23m wide. The fixed leg ARC’s are based on fixed circle segments and special angled corners. The tower ARC’s have a hinged system using straight elements and on top a keder profile for full closing and flexibility in depth. The ARC Roofs carry the highest load capacities and are mainly built from standard Truss sections.
