The main hangar structure is made by couples of connected 300m length steel truss beams, each 9.1m, supported in the transversal direction by steel RSH beams. The parabolic geometry of the extrados of the main beams allows a better rainwater outflow.

Main beams together with vertical and horizontal bracing system allow to get a spatial frame, stable even out of its own plane.

The five main frames that composed the main structural system are laterally stabilized by RHS reinforced concrete columns.
