The steel structure is composed by a stand on the highest level and its global roof system which is supported by a 6.44 m Reinforced Concrete element that surrounds the entire stadium.
The steel structure is essentially constructed with the following components:
Step support beams, spaced with 6 metre constant pitch
Structure of main roof, consisting of 14 large cantilevers arranged on the same vertical plane of the step support beams; each cantilever is formed by a spatial reticular macro and balanced by a vertical pillar that reaches the ground.
Secondary roof structure, consisting of rectangular section beams arranged radially.
Roof coverage membrane, made by panels, composed of polyester and highly resistant PVDF, double curvature and pre-stressed.
