Nearly 5000 Sqm of translucent covering for "El Sadar" Stadium

El Sadar Stadium In 2020 on the occasion of the 100th anniversary of the founding of CA Osasuna, among the many scheduled events, the club decided to renew the completion of the El Sadar stadium.

The stadium was initially inaugurated on 2 September 1967 with a match between the Spanish of Real Zaragoza and the Portuguese of Vitoria Setubal took the place of the old San Juan stadium and took its name from the Sadar River, which flows just west of the city.

Initially, it could hold 25,000 spectators of which 7,000 seated.

The renovation was entrusted to OFS Architects, one of the most important Spanish architectural firms, with their "RED WALL" project, for which 16 million euros have been allocated and which provides for an extension of the capacity up to 24,500 seats. of which almost 1,500 standing to satisfy an explicit request of the most passionate Rojillas fans.

To create the translucent part of the roof to protect the terraces, our Grecapiù 40/10 5G was chosen, a corrugated sheet with a 10 mm thick honeycomb structure, in the opal color, for a total of 4,850 square meters.

The opal color allows the light that passes through it to be distributed evenly and without glare, also partially shielding its intensity, giving exceptional visual comfort to those in the stands.

The sheets were made in a single piece over the entire pitch, reaching a length of 13.7 m.

To prevent them from getting dirty inside, they have been sealed in the factory by heat sealing.

The sheets mounted on the four corners, cut on-site, were closed with a special aluminum tape.

The assembly was carried out on a load-bearing structure with crosspieces perpendicular to the development of the slab, placed at a pitch of 2.33 m, a distance that made it necessary to integrate the slabs with an aluminum reinforcement profile, mounted under each joint and, in the most important points. stressed, even under the central corrugation of each slab.

The lateral joints between the various sheets were protected by a continuous sheet metal work, while the fixing to the substructure was made with self-drilling screws, integrated, depending on where they are located, with a baz washer (on frets surmounted with continuous sheet metal) or with a cap (on central frets).
