Safety: Every ZENDOME has a certified and tested static by the German TÜV.
The according paperwork that certifies the model approval for the relevant authorities is issued by the TÜV Rheinland.
The wind loads where calculated according to DIN 4112 with a dynamic pressure of 0,5 kN/m² for heights up to 8m and 0,8kN/m² for heights of more than 8m.
In order to determine the according coefficient for a hemispherical cupola the constructional calculations for engineers where taken as a basis.
Also taken into account where the junction loads of wind for the tunnel extensions at the entrance and exit of the cupola.
*ZENDOME.30 and ZENDOME.75 do not require a written verification according to DIN 4112, because it is under 75m² of base size.
