The textile roof is made of polyester fabric coated with PVC on both sides (Atlas art. 760 type IV - TFL, Sattler brand) and consists of 43 independent tensioned membrane units of different dimensions, distributed in 13 membranes over arches, 28 membranes under trusses and 2 lateral membranes.
The total membrane area is approx. 6,252 m2, with a projected area of 5,910 m2.
Each membrane is made in one single piece and is fixed to the metal substructure around its perimeter by means of a frame made of aluminum profile lacquered in white RAL 9010 and stainless steel metal strips.
In the case of the large tarpaulins between trusses, the membrane is also fixed to the arches by means of an aluminum profile lacquered in white RAL 9010. These, in turn, are reinforced by galvanized steel cables, anchored at the ends of the metal structure.
