The ARC Roofs are available in a fixed-leg (up to 10m/32ft wide) and in a tower version (from 12 to 24m/39 to 78ft wide). The fixed leg Arcs are based on fixed circle segments and special angled corners.
The tower Arcs 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.
