AshZip Load Spans

All loads are characteristic working loads in kN/m² based on 4 or more spans
In deriving the figures below the following criteria was applied:- 

Strength 
Safety factor for vertical loading 1.6.
Safety factor for wind uplift loading 1.4.
Safety factor for detachment of sheeting from halters under wind uplift loading 2.0. 

Deflection 
The download figures are based on a deflection limit of span / 200
The wind uplift figures are based on a deflection limit of span / 180 (aluminium).
The wind uplift figures are based on a deflection limit of span / 120 (steel).
