Martifer Metallic Constructions is responsible for developing the roof structure, which is independent of the concrete structure and will be covered with screens. The 40 metal structure cantilever beams will be supported by sets of pillars and tie rods on the outer perimeter of the stadium. The beams will be secured by sets of 18-metre arches covered with screens. The façades will also consist of micro-perforated screens, connected to the external metal tie rods.
